Seagull Nebula in SHO - 31 hrs

[AnakChan (Sean)]

Here's my version of the Seagull Nebula in SHO over 31 hrs worth of integration. I took this between 26th Nov - 24th Dec using my ASI6200MM Pro camera with Antlia Pro 3nm filters through the Takahashi FSQ-85ED. Having being used to taking pictures with my Takahashi µ250CRS at 2500mm FL for years, the FSQ-85ED with the ASI6200MM Bin1 resulting in a resolution or 1.7"/px, it was a breeze to guide with the Vixen AXD mount. I've actually had the FSQ-85ED for over 4 years but never really used it properly. The last time I did was for the SuperBlue Blood Moon back in Jan 2018.

The sensor was cooled to -10C (a struggle in the hot summer nights), Bin1 Gain 100 Offset 50

Ha: 60x 600sec
Oiii: 63x 600sec
Sii: 63x 600sec
Total:31 hrs under suburban Bortle 6 skies.

Edit: added a toned down version as per Andy.

That's got bags of impact!

Having said that, maybe it's worth turning the saturation meter down from 11 to say 8-9 for a more subtle but still bold appearance as it looks posterized

Thank you Andy! How's this one? I've toned it down a tad.

For sure that's an improvement, but you could go further - especially in the O3/Cyan area, it really should look like gas.

Here is a reference pic for you. So you can see what I'm referring to.

Cheers! Wow, so almost a pale blue. Got what U mean now !

So much data there! Ha is absolutely bursting at the seams. I remember putting maybe 2 or 3 times the data in Oiii than the other two to bring the blue out a bit, but then I had nowhere near the depth that you already have.
It's already phenomenal and I'm looking forward to seeing where it ends up

Great image with a real impact, the stars are a little muted though that would have sealed it for me

[ChrisV (Chris)]

That's phenomenal. There's much more in it than the ref pic Andy posted

[AnakChan (Sean)]

Thanks for the compliments folks! Yeah for the stars I may have reduced them a little too small. When I recombined the starless back with stars, I used the PixelMath formula of starless + (0.6 * stars). I probably could have done it with 0.8 instead.
