Description

A new version : SHO version2 , more natural , with better RGB stars,
tell me what you think ?

Just a zoom on the Lion 's head
-------------------------
I had this project in mind for a long time (like the the Veil nebula) this lion Nebula is a large one , it really needs a wide field setup.
With the new 24x26 CMOS, I thought it was a good time to have a try !
