First time in a long time I have been out with the camera and telescope. The bad weather has just always lined up with my nights off of work. And boy have we had a lot of bad weather over the winter..
So I thought I would return to a favorite of mine, and one I tried imaging last year too.
Unfortunately, the "astronimically dark nights" are already done for this part of the year, so I could only squeeze a few hours in of imaging over the two nights I did this, the get the darkest of them, and had some telescope issues the second night, so I had to scrap 1/3 of the images.
The first night I also forgot to take dark frames, so I just applied the ones that I took the second night to those, which worked out great too.
Messier 64 (The Black Eye Galaxy)
Skywatcher 150PDS
Celestron AVX Mount
Nikon D5200
Baader 2'' Neodymium filter (haven't tested the actual difference this one actually makes).
Explore Scientific Coma Corrector
ISO 800
26 subs, 8 mins
3 hours, 28 min total (over 2 nights as it only gets nautical dark here)
Manually stacked and processed in Photoshop CS2
Dark frames used, but only 6 of them.
I've used a LOT of time, doing countless iterations of processing on this one, especially on the color/balance and trying to keep both galaxy detail and star color, so any advice or comment on it, would be very much appreciated.
But considering how bright the sky was, even during the darkest part of the night, I am quite happy with the amount of detail I could pull out. I'll have to return to it next year, during the dark nights

Before the grey nights set in, I wanted to get some more sketching done.
The 10" ACF and I went to a fairly dark spot in the Netherlands, for some 4 hours of observing and sketching.
The results:
