Very nice indeed! Note that the following is a serious question and is in no way intended to diminish your accomplishment and the complexity of producing this sort of image . . .
A classic problem with newbies is the tendency to put the main subject in center-frame. A similar problem with us more experienced types (i.e., oldies) is to ignore composition while working through new techniques. So, in that context my question is whether the composition in your m31 shot is satisfactory for you, or if it is just incidental to the experimentation process? I also wondered if there is something about the way the astrotracer works that makes it desirable or even necessary to center the main subject . . . I like the image but would like to see it cropped to bring the m31 downwards and to the right. Or re-shot with that framing in mind. stan On Oct 15, 2013, at 7:00 PM, Darren Addy wrote: > Y'all may recall > (hey, that rhymes!) > the m31 (Andromeda galaxy) image I shared a few days ago.
