Title: Another "filler" - Flame and Horsehead in Orion - RHaGB
Post by: Roberto on Mar 03, 2021, 17:44:27
Hello All

Trust you are all well.

Another image taken whilst waiting for other targets to rise - with the Moon around.  Very short exposure in total, less than 5 hours but these bright objects lend themselves to being stretched...(don't look too closely though  ;) )

A very nice "filler" Roberto.  Amazing control of Alnitak.

Thank you Carole, Duncan - very kind.

Carole, the OSC exposures were only 150s which helped.  PixInsight is very good when stretching images to non-linear and keeping star cores unsaturated.  Then Mark's Arcsinh Stretch did the rest.

QuoteMark's Arcsinh Stretch did the rest.

Mark did a tutorial on how to use this in Photoshop, and I used it a couple of times and it was great, but then it kept failing for some reason I can;t remember now, so I had to devise my own system of getting colour into the stars during stretching. 

So long since I have done any broadband I have almost forgotten how.

Great image.

The colours look spot on.  As a whole it has a very ethereal quality.

The ethereal part may be because it's low on the horizon and the focus is soft!  :lol: :lol: :lol: :cheesy:

Yet another one I missed  :-?

That does look very good.  I'd not noticed that blue reflection nebula just north west of the Flame before ! Great capture.
