Well...sort of...
I was setting up to image Mars on a couple of occasions last week.
First with a C11 & a few days later with a C14.
I wanted to have a go at NGC2207, but thought it a waste of time from the 'burbs of Melbourne.
Regardless, I took 8x600s images through the C11 at prime focus (pinpoint said 2940mm) on one night, and then 4x600s images through the C14 at a native 3900mm. All frames were just luminance. 2hrs total.
Needless to say, I got some fairly significant coma & even some field distortion over the frame through these scopes, but I dark subtracted all of the data & combined it.
Attached is the result cropped at 100% to show 2207.
I know its not all that deep & is in b/w, but it was an interesting exercise.
I was amazed that some of the frames came through with very low FWHM's at 1.6" or so..
Processing was just dark subtraction & histogram scaling; no sharpening. Tried my hand at a little field distortion correction too, but I don't think that it made too much difference.
Hi Maurice - nice capture.
I hope you don't mind?
I processed your pic since you hadn't.
I removed the bright stars - stretched it,
added noise then reduced noise.
I then put the stars back & reduced their size.
I sharpened only the core.
The processing would have been much better with the original FIT 32 bit stack.
It would be worth putting in more time as there is quite a bit of signal.
I like the long focal length pics.
That's a great image scale you have there. Very close up and personal.
Greg.
Thanks Greg

Thanks Allan. You got more out of the 8bit data than I did out of the stack. I will have a go at processing the data a little better & see what happens.

Thanks Ray.
Yep, so far so good with the EQ8. Still haven't mastered the correct guiding settings with the weight of the C14 on there though..
That's looking really great, what a fantastic image scale I'd love to see a deep version of this, hope you get to put some more hours into it, that would definitely be worth it. Great work!

Thanks Maurice,
I like processing data.
It's amazing what can be extracted out of it.

Very nicely done indeed.
