Cygnus Loop finished! 13 hour Ha+O3

[MartinF]

Last night I finally managed to get some more O3 data for my Cygnus Loop image.

Despite being captured during full moon (Ha) and 80% moon (O3) the faint structures are visible. I guess those 3nm filters really do work

94*5 minutes of Ha
66*5 minutes of O3

Processed as bicolour with synthetic green from 30% Ha and 70% O3.

Unfortunately I´ve got weird star shapes in the outer parts of the image due to the lens I used, but I might make a separate stack with just the best subs for stars or I might replace them with RGB star later on.
Still very happy with this one!

That's a beauty, Martin!

Very nice, Martin...
I'm in the middle of a 9 panel mosaic of this in the same palette...
I hope mine looks as good when complete!

That is a really sweet compilation, Martin. Nice wispy detail throughout. A fine effort!

This is superb! , i have a few questions
why a blend off ha and oiii as the green channel ? and not the usual oiii as blue/green, does it help processing a bit easier ?

what was the imaging setup you used ?

thanks for the time on target, really like the image.

Amazing image, love the colors.

[jerrysykes]

Outstanding image, Martin!! One of the best I have ever seen.

[MariusD69]

Very impressive! Great work, Martin!

Thank you!

For me it makes the colours look more natural. I use the workflow from lightvortexastronomy.com.

I used my Zwo ASI1600MM-Cool with my Canon EF 300/4L IS tele lens. Filters are Astrodon 3nm.
HEQ5 Pro Synscan mount on pier in my backyard. Orion MMAG for autoguiding.

That has to be one of the BEST C-loop images I've ever seen.

Beautiful.

Wow! Beautiful

Love the details and parts of it have an almost natural 3D effect!!!

Beautiful work, Martin!

Man, Martin, that is really nice!

Great work!

Awesome image - great effort and wonderful capture and processing. Yes, the 3nm versions of Oiii are wonderful.

[MartinF]

Thanks again for all you kind comments! September has been a good imaging month for me

[jthommes]

Well done Martin. Nice work.

[Thefatkitty]

In a word, Martin: Wow. That is really impressive! I'll get back to you on the print thing later; been a hectic week

Thanks for sharing that and all the best,
