Description

Subs taken last summer from my second setup.

It's tempting to replace the cheap achromatic refractor with at least a doublet but I'm forcing myself to get the best out of this setup and to squeeze every little bit of data out of the subs!

I changed the processing a bit making the stars smaller just after stretching instead of doing after HDR/local histogram transforms (I still do again at the end though), seems the result is better and stars are less bloated compared to my first image on this setup, enjoy!
