Description

My first attempt at M42 HDR. 30 lights at 60secs and 47 lights at 300 secs, plus flats, darks, bias, etc. Used PIS to make the HDR. I had some serious halo/vignette pattern going on initially and reached out to the forums for help. Got a lot of good ideas/feeback and eventually narrowed it down to poor post-processing technique. I was able to get rid of the huge halo pattern for the most part. Also learned my focal reducer/flat field it not a good fit for this scope, so I'll either try without it or look for one better designed for this refractor. Always a learning experience.
