processing notes.
Got the images from 8/13/18 at 1:00 AM
working in Nebulosity.
1) pre process, with dark and flat frames.
2) align - using translate and rotate. At first I saved all the images, this is wasteful, but allowed me to see what was going on.
3) stack - using average.
3a) manual identification of the star takes a good deal of time
3b) automatic appeared to work essentially as well.
3c) to get maximum resolution in an area (In this case andromeda), pick two stars near to each other in this area. In this case, auto also worked well.
There was smearing of some of the stars outside the area of interest - so what.
I am surprised at how well I was able to pull out some detail. With the 24mm focal length, I was able to barely see M32, and some Mag 9.2 stars.
can them move them to Lightroom to crop, etc.
Issues:
Color rendition is a problem. When you pre-process, the images come out as .fit files. I cannot see that they have color info. I might move a single image into Lightroom (via tiff ) to see if there is some color info. Alternatively, there might be a way to examine the image header.
still some frame rotation in the images. May be unbeatable.
Try this entire process in PixInsight and document it.
