I am not as happy with this as I was hoping I would be at this time. I
probably have about 10 hours exposure binned 2x2 at f/12.6
one issue is that I haven't had proper darks and have had to get by. It
makes the image a bit noisier.
another is that I have a peculiar reflection in my [OIII] flat/filter in
this scope that I have not seen in my 400mm camera lens
I suspect that there's something reflecting some light somewhere and is
better at reflecting green than red
I also have a bit of a problem with reflections in my main baffle tube. I
believe those are responsible for the large offset haloes around the bright
stars.
I changed how that was flocked during the spring and now I can see that to
get the results I want I need to further refine that.
all excuses aside here it is.
at this scale it looks better than at full rez :-)
That's a tulip color never seen in Holland! Interesting.
