Description

Heart nebula - stt-8300m + 5nm astrodon Ha + canon 200 f/2.8L @ f/2.8

focus is difficult at f/2.8 but since the lens only has to focus one frequency, it's possible to use it wide open and get sharp stars. with OSC i used to run this at f/4.

rev B with 5 more frames (+25min) and background extraction
