M 42 - Orion - 2013

[jsmoraes (Jorge)]

GSO 305 mm - Canon Rebel XT - iso 800

Multi-process:

group 1: nebula background - 5 x 90 sec

group 2: nebula center - 5 x 60 sec

group 3: nebula center trapesium - 20 x 20 sec

group 4: trapesium - 20 x 10 sec

Yes, I know. Much sharp, and therefore noise, because of bad focus. Sorry, it was my fault.

Not far off focus Jorge , , The central neb is very smooth indeed, & dig the colour rendition also
May need longer subs to help the outside fainter Neb tho, I find, I think the noise you mention in this area could be more likely processing ? not 100% sure, but longer subs for this area should help this aswell ?
I really like tha colours in this and the smoothness is great, Well done !

Thanks, Bob. Some noise was increased with the process to reduce lack of focus. I needed to use much sharp and surface blur in Photoshop to show a better image.

No problem, Orion will be there for much time to permit me try again

A coma corrector is coming. I hope to obtain a better shape of stars at periphery.
