From Brian
@ . . . . . . My apologies for taking so long to
send these images...managed to get time to assemble them today. Please let me
know if you have any questions. Take care,
(
@ . . . . . . I have attached my latest images of
Jupiter taken on Nov 17.
I used the
30cm SCT telescope at f27 through an
AO-2 adaptive optics unit. The camera is a Pixcel 237 CCD operating in hi-res
mode and the two IR images were obtained with an IR passing filter centered on
894nm, 337nm FWHM. Note that the first IR frame has not been properly flat
fielded resulting in some artifacts on the disk of Jupiter. The angled line at
the top of the image is a processing artifact, a result of the disk being close
to the edge of the frame.
The IR+RGB
image was created by taking a colour image with a Logitec WEB Cam (same optical
setup) and replacing the luminance portion of the image with the hi-res IR
frame and converting it back to an RGB image.
This was the
first night to test the webcam, but the results look promising.
