Thanks Sara. First things first: Congrats on the recent APOD!
Re this image; it was a compromise from start to finish. Imaging at f/8 on the FSQ106ED works OK but one really needs the best conditions. So with at least 80% humidity each night I was imaging, there was no way that the optics were up to 0.7 arcsec/pix. (Even on a dry night – that would really be stretching the guiding capabilities of FS60CB guide scope….but I think possible on a decent mount). So I binned all the subs to image at 1.5 arcsec/pix.
I also compromised on the time. I had planned on over 20 hours total but as you are well aware – clouds just kept rolling in lately here in SE Spain. So the 14 hours total is way less than I had hoped for but thought that I would process it anyway. End result OK....but with more patience I might have made it better.
I have left the extender on the scope….I will experiment some more when I have better conditions. Really looking for a chance to image at the higher resolution to make a final decision on the full worth of the extender… the challenge is what makes it interesting.. One way or the other however....it is great to have the option to work with/without extender or reducer on this particular scope.
