Bellisismo off the field ... but it seems a little simplistic as the title alone Horsehead !! :-D Given the immense amount of visible objects: Flame, Barnard's Loop, M78, etc .. :-D
Compliments ;-)

Elio Hello, thank you for appreciation.
Wow, you do not miss anything! In fact, the flat out of laziness I have not just made them ...: - | :-(
I plan to do it and rework the whole thing because the image it deserves.
Best wishes,
Giorgio

Ah here ... :-P
worth ... worth ...
If you usually use the dark, for a session, try to resume flat / bias and to calibrate the images without dark ... maybe you can break down otherwise the noise ... ;-)

And of what! is evidence I do since a friend (Matthew Hill www.cumsidus.it) put me in the head that the dark with new sensors and new PixInsight calibration techniques and "sum" are no longer necessary ... better make bias at each session with flat "exact", and a good dithering! :-)

Given that you have 50 frames can be added using the linear fit (I think you call it so) Recommended for more than 30 poses ...

As they say in my part ... test, it's free! :-D
