Received: 15 June 2016 at 00:16 JST

Thanks, Roger
Yes, and specifically on that evening, focussing was very difficult. The monochrome G and B's were a real "hit and miss". It is another advantage of the ASI224MC in poor conditions that you can take a string of L captures in the hope that at least one of them, by chance, may get a good focus point. That has been a technique I have been using throughout the apparition, which has, so far been dogged by poor weather and seeing. This has given me at least reasonable results. The cloud we have had for the last 3 days is forecast to clear during the evening, so I am hoping for some luck tonight.

Best regards,

Clyde FOSTER (Centurion, SOUTH AFRICA)

Received: 14 June 2016 at 23:53 JST

Hi, Clyde –

I agree with your conclusions regarding the images that you presented. However, I suspect that there is a confounding variable in your analysis, which is focus.

With your usual color captures, you are dealing with a brighter image on the screen, which allows you to focus more accurately. With monochrome captures, there is likely to be a slight difference in focus among the three colors, so that you might need to refocus between monochrome color exposures. Should you need to refocus, images of lower contrast (green and blue, on Mars) will be focused less accurately, if you focus by judging the image's appearance on the screen. In looking at lots of images, I have seen that many blue-filtered monochrome images of Mars lack crisp edges of albedo features. Focus is a problem.

In principle, monochrome images should be slightly better because they suffer less from atmospheric chromatic dispersion than color images do. In practice, this is offset by the greater difficulty of obtaining accurate focus.

In my opinion, that is.

Roger VENABLE

¤····Subject: Mars 2016/06/10 "L decomposition" compared with RGB

Received: 14 June 2016 at 22:44 JST

Hi,all

I had the opportunity on the 10 June to retest my ASI174MM, which I have had a real struggle to clean from some dust motes.

Having taken my normal ASI224MC captures(submitted previously), I took a series of R, G, B and IR captures with the ASI174MM.

My objective was to see whether there are concerns with the “L decomposition” methodology (Luminance filter with a colour camera, channel split in Photoshop) that I have been using for generating the R, G and B images on my regular image sets, as compared with monochrome RGB imaging. More specifically, I wanted to confirm whether there is value in the “L decomposed R, G, B” images, instead of just submitting a single colour(L) image.

A few notes:

1. As per my original images from the 10th June, unfortunately seeing conditions were poor/below average, so it is possibly not the best conditions for this exercise.

2 .Also as previously noted, focussing was a real challenge on this evening.

3. Calculated Image scale for the ASI224MC is 0.07”/pixel whilst the ASI174MM is 0.10”/pixel.

4. There is a slight time difference between the comparison images

5. The processing of all the images was not identical, so this can impact on the comparisons somewhat.

6. My understanding of at least one of the concerns about the “decomposed RGB” methodology is that individual colour channels can be contaminated by “leakage” of the other channels.

Attached is a comparison of the decomposed RGB images from the ASI224MC with the R, G and B captures from the ASI174MM. I have also included IR captures with both cameras.

My comments on the results:

a) Red

a. The R monochrome seems to provide a slightly higher resolution than the OSC decomposition.

b. Looking at the Hellas cloud, there may be some “leakage” of B and G components, which has brightened the cloud in the OSC decomp R image.

c. I note that the NP cloud shows a R component in both images.

b) Green

a. The monochrome G image is a bit “burned out” on the Hellas cloud.

b. The monochrome G image quality is not particularly good, possibly due to the conditions and difficulty in focussing as mentioned above.

c. Resolution of the albedo features may be a bit better in the OSC decomp image. This may however be due to R “leakage”

d. Clouds may be showing a bit more strongly on the monochrome G image, although this may be due to processing.

e. Other than the above, my personal view is that the OSC decomposition gives a “reasonable” comparison with the monochrome G.

c ) Blue

a. The monochrome B image quality is poor.

b. The Hellas cloud appears to show more strongly in the monochrome B image, whereas the Northern clouds are more comparable.

c. Albedo features in the OSC decomposition may be due to R “leakage”.

d. Again my personal view is that the OSC decomposed B gives a reasonable comparison with the monochrome B

d ) IR

a. The monochrome IR is a bit more processed that the OSC decomposition

b. Possibly the monochrome may show a slightly better resolution, but in my opinion, it is only slightly better.

CONCLUSIONS:

• This was a single exercise, performed under non-ideal conditions, so any interpretation should be handled with caution.

• It is my personal view however, that should seeing or weather conditions impose constraints, that the “L decomposition” methodology can provide at least “reasonable” RGB decomposed images and some added-value to the image interpretation.

• With my personal objective of imaging Mars on every possible occasion, irrespective of angular size, weather and seeing conditions, with the intent of monitoring the planet as comprehensively as possible, in situations where seeing and weather imposes significant observing/imaging constraints, the use of the “L decomposition” methodology is, in my view, a reasonable compromise, and can provide at least some additional data, where RGB imaging may not be practical.

• I do not challenge the advantage of using RGB imaging as the preferred methodology, when conditions are suitable, and do not see the L decomposition methodology as competing with high quality RGB imaging. On the contrary, I remain with a personal ambition to achieve the hi-res RGB imaging standards that are being set by the best.

• I appreciate that there are likely some strong views on the above in the imaging community, and that I may get shot at/down on specific points! However, I personally wanted to undertake the exercise for my own interest, and felt that there may be benefit in sharing.

As always, any comment or feedback is welcome.

Our year to date rainfall is currently 80% of our total annual average; the bulk of it occurring since mid-April. I finally got some clear skies last week, so attached are images from the mornings of June 8, 9, 10 and 11.

It's cloudy and more rain expected later today but hopefully I'll get some more clear skies later in the week!

Thanks for the comments Jim!

Yes, I guess I should not complain about the seeing, particularly with the elevation of Mars from down here.

The seeing has however been unusual these last few days before a cold front swept in over the weekend. I would refer to it as “micro” poor seeing. Rather than the image jumping around and “boiling”( although I am getting this a bit earlier in the evening), it is very fuzzy, and difficult to focus. I suspected an equipment problem, but other local observers are also experiencing it as well. We have rain and cold at the moment, but should hopefully start clearing tomorrow. I am enjoying the various comments and feedback on the images from Roger and yourself and also from Gary (Rosenbaum) the other day. Richard also commented on the wind direction which would support the “plume” of cloud/material being blown out of the Hellas Basin this last week, which I found exciting. It is really interesting to get proposed interpretation of the images related to the geography and meteorology of Mars. Bit by bit, I am learning more about this fascinating planet. For those that are not on ALPO Mars Observers, Gary’s comments on my Hellas images as follows:

“Hi, Clyde

You are getting some really good images of Mars. Both Jim and Roger have already made some good comments on the dust situation in the Hellas area. In a very general sense during this season on Mars(Ls 165 deg) the mid-afternoon flow within the Hellas Basin is clockwise with a west to east flow in the northern region and an east to west flow in the southern region. Sometimes the winds increase in speed and carry dust from the southern part of Hellas over the rim of the crater to the west or west/northwest which is probably what we are seeing. Since the southern edge of Hellas is in close proximity to the SPH there can be some white cloud mixing with the flow of the crater. The SPC should be formed by now and the strong thermal gradient between the ice and the warmer exposed surface creates a cold flow off cap. The downslope along the southern edge of Hellas enhances, channels and concentrates the off cap flow and the surface wind stress is highest in the afternoon along the western rim of Hellas. We don’t see evidence of this all the time but it is not exactly rare so I would not call it a disturbance. This time of year there is a net transfer of water vapor from the northern Hemisphere to the southern hemisphere and there will be an increase of frontal storm activity in northern latitudes. These storms travel east and along the leading edge warm air is transported north while cold air moves south along the following edge. Oftentimes there will be water ice clouds associated with the storms and occasionally some dust activity as well. Active areas for these storms are near Acidalium and Utopia”.

Hi Clyde,

Please send me your poor seeing, I'd be glad to have it. Ha! Your image shows a 'white' cloud over NW Hellas. I'm thinking that it's CO2 vapor and that the SPC's invisible CO2 slab ice has started to sublime. Maybe the sublimation started in mid-to-late April. We know that sublimation at the poles produces wind, right. When the visible granular H2O cap sublimes, a dark collar appears around the cap, where high winds blow bright dust into the air uncovering dark mare. Does anyone see a dark collar now? I'm going back to images in April and see when the wind started blowing dust into Hellas.

Good seeing,

Dear Mr. Minami and Mr. Murakami,
I hope you are both well. Please find attached two RGB sets I took of Mars last night (June 11th). The seeing was good and I had a view of the Tharsis region. The B images show the clouds over the volcanoes getting stronger as they move to evening, other than that the disk of Mars was fairly quiet.

Thank you,

Dears,

Jupiter far from meridian, at a low altitude hence low resolution. GRS is rising, preceded by the STB ghost, and on the North there is a strange oval ring which looks like its connecting two bands. There is a small eruption at CM in the middle of SEB as well.

Only IR shows details: http://www.astrosurf.com/delcroix/images/planches/j20160605i-21h27.7UT-MDe.png

Hi all,

I am afraid seeing conditions have been exceptionally poor the last two evenings, with focussing being a real challenge. I am amazed that the ASI224MC is still able to eke out at least some of the major features. Cloud activity in Hellas is continuing. I also note the two reddish lines over Syrtis Major, although any detail must be rated as a bit suspect under these conditions.

Hi,

Surprisingly good seeing during my first sessions of the season for Mars and nearby Saturn last Sunday night, with the planets at only 18° altitude.

Mars showing some nice details in the murk but an absence of cloud detail due to the reddening. Saturn with an ASI224MC OSC camera and then this colour image overlaid with luminance from an ASI174MM mono camera with an Astronomik 642nm filter to sharpen up the colour image.

Saturn in particular a testament to modern cameras, processing methods and particularly ADCs.

Thanks, Jim.

I had not noticed the dark line in Hellas on the 6th, but do take note of it now.

The images I sent through this morning I think are fairly conclusive in confirming the linear cloud as a plume emanating from the Hellas disturbance. Interesting that it seems to have funnelled through/over the western wall(rather than a general overflow), although I estimate the plume probably to be over 200kms wide!

Busy with some more captures now, although seeing is, to put it politely, “poor”…..

Hi Clyde,

I think that's some of the airborne dust overflow from the wave of dust hitting the crater wall. Oh, and your June 6th image shows a dark line going from the SW to the NE in Hellas presumably the wave of dust that would hit the crater wall on the 7th. Yours and other high resolution images make this analysis possible. The dark lines in Hellas are not artifacts. If they are, then we might as well give up. That's my opinion.

Good seeing,

- Hellas disturbance and "plume", NP cloud front

Received: 9 June 2016 at 18:00 JST

Hi all,

Two image sets from last night. Seeing was average/below average.

There is some nice activity taking place.

Regarding the Hellas disturbance:

a) It appears to me that this is a “mixed cloud”, including a reasonable level of dust.

b) The cloud seems to have changed shape and consolidated/concentrated a bit, although take note of my comment f), below.

c) The “subtle” linear cloud extending WNW of Hellas that I noted yesterday is very clearly seen in the 18.10UT image.

d) It is my view that the 18.10UT image links the linear cloud with the Hellas disturbance, hence I would be tempted to refer to it as a “plume”. Ie It appear that material is being blown out of Hellas and driven in a WNW direction. Other views/comments would be welcome.

e) It appears that the plume is quite dynamic. Note in the 18.50UT image(only 40mins later), that the rim of Hellas is visible where the plume crosses it, which is not the case in the earlier image.

f) When rapidly switching between todays 18.50UT image(I deliberately tried to capture the same CM) and the 18.11 image from yesterday, a lot of changes in and around Hellas are noted. It appears that there is a lot of dissipation of material across Hellas and also in the close surroundings. The indication is that the disturbance has had quite a wide influence.

Over and above the Hellas disturbance, there is a large cloud front adjacent(following) to the NPC which has developed over the last 24hrs. The following edge of the front is notably sharp. There is also quite a concentrated cloud formation on the preceding side of the NPC.

Dear friends,

I have image Mars a few nights in early June but not yet finished the processing, but I hope to send them in the coming days. The planet is beautiful sight with Saturn and the head of Scorpius low in the south, and with the mild summer nights observations are a true pleasure!

Here's a view from last Friday night with unusually good conditions, seeing went up to 5/10 occasionally. Hellas on the evening limb has a thin yellowish haze unlike the other blue-white hazes along the limb. NPH is small and Orestes quite prominent.

I also include a drawing made afterwards (a scan of the observing form), and a photovisual comparison. The altitude was 13 degrees at imaging and 12 degrees for the visual observation.

Any thoughts on the subtle linear cloud extending from Hellas to the West(WNW)? I am not sure how clearly you can see it on the image. It is more clearly seen on the 2nd image I submitted(at CM302). Do you think it is just a fine temperate linear cloud or related to the Hellas cloud? I am busy with the captures from yesterday evening, although seeing was not particularly good.

Hi Clyde,

I think this cloud is similar to one you recorded on May 9th. As I proposed in ALPO's highlights page, it may be caused by another wave of dust moving Northwest in Hellas crashing in to the NW crater wall. It will be interesting to see imagery of this region June 9, 10, 11th.

Hi all,

A second submission from yesterday evening taken a little over an hour before the previous image set. In this image, the linear cloud which appears to extend from the rim of Hellas, expanding and dissipating to the west(right) is seen a little more clearly(although still subtle). In particular it is seen more clearly in the G and B images than in the previous image set.

To expand on my “theory”: Is it possible that there is an “East South Easterly” blowing over Hellas which is pushing a “mixed cloud” of cloud and dust (I say this as there does appear to be a R component in the cloud) against the western wall of Hellas? Further, if there is a small breach in the upper western wall of Hellas, the cloud is being pushed up and through this breach, resulting in the linear cloud extending to the west north west, expanding and dissipating towards the limb? I am not sure about the prevailing winds at this time of the Martian season, so I may be way off the mark. However if anyone has any views or comments, I would be interested to hear. This may support, at least to some extent, some of Jims recent commentary on Hellas winds?

Hi all,

Getting some reasonable seeing, although we are expecting a cold front later this week. Attached image from last night. There appears to be residual cloud on the western(right) side of Hellas. What I noted in processing a number of images from the evening was that there is a very fine line of cloud extending westwards and slightly north from Hellas, expanding and dissipating as it gets towards the western limb. It is very subtle and probably best seen in the G image. It is almost as if cloud is finding its way through a small gap in the western wall of Hellas and being blown westwards. However, this is only a theory. Comments would be welcome.

Hi all,

Returned yesterday from a one week trip to the Golden Gate Highlands National park on the border of South Africa and Lesotho. A really beautiful spot with extensive sandstone formations. But nice to be back at home in the observatory again and there was some reasonable, although mixed, seeing last night. Mars image set attached, with some extensive and interesting cloud structure over the Mare Acidalium region. We are approaching the Martian Southern Spring Equinox(Ls 180), so there is that growing excitement and expectation whenever Mars appears on the screen, as to whether there will be any brightish red/yellow regions showing. I am not noting anything of significance as yet though.

Hello everyone,

I managed to capture the same CM after a two day interval. The changes in the cloud pattern are interesting to compare.

Bad weather has set in now so I may not be able to do any imaging for a while.

Best regards,

Dear Sir,

Attached find two new Mars images. Since the altitude in Holland is only 15 degrees, I used an ADC.

Regards,

Dears,

Depending on the images, the 6 closest bright satellites are visible in the field of the camera. The northern hexagon with its central vortex is visible, and on the infréared image a bright equatorial spot. I'm rather satisfied with the results given the low altitude (~25°). Here are the most interesting images:

Hi Clyde,

Have fun! Your image shows a lot of airborne dust scattered around in both Hemispheres. This should be monitored to see if a global dust storms grow out of this.

Dear friends,

I acquired Mars last Friday night under unusually good seeing conditions, but unfortunately it is still only 13 degrees high at culmination (the ADC is not able to fully compensate the atmospheric disperison). Quite tediuos work getting anything decent from the avi's, particularly the color balance is problematic.
But I am quite satisfied as it is the best image for me this season, and now some more interesting albedo features are starting to come into view.

I'm also attaching a better processed May 20 image.

Best wishes,

Hello all

I have updated the animation sent yesterday of Mars' rotation to include data fron 1209UT to 1323UT. To make the file a reasonable size, I have compressed the data, which has made the result more grainy with the loss of some fine detail. Individual RGB frames will follow in the next day or so.

Best wishes

Hi everyone,

Last night the seeing looked very promising early on in the session but unfortunately it did not last long enough to catch Mars at a higher altitude.

Even so I think this is my best Mars image set to date.

Best regards,
