I’ve been doing AP for about 7 or 8 years now, on a somewhat intermittent basis, as I live in an area with lots of light pollution and overcast skies. For the first several years this was little more than electronically-assisted observing - I’d get a picture of something and be thrilled I could see it, and in terms of image quality, was mainly concerned with getting a decent signal to noise ratio.
In recent months I’ve started putting a lot more effort into developing my acquisition technique and learning some of the finer points of AstroPixel Processor, but I’m thinking it’s probably time to buy a book. I imagine I’ll eventually switch over to PixInsight, but for now I’m looking for a more general book rather before I leap into learning a new, big, complicated piece of software.
So coming coming to the point, what are your recommendations for AP books suitable for the advanced beginner?
