Lagoon Nebula in SHO

[AnakChan (Sean)]

Lagoon Nebula taken over 4 nights (20th May, 1st, 5th & 6th Aug) with my Takahashi µ250CRS at native 2500mm F10. The camera was the ASI6200MM with Antlia Pro 3nm filters.

Skies were Bortle 5/6, and I had cooled the sensor to -10C, Bin1, Gain 0 (yeah don't ask ), Offset 50. The final comprised of :-

Ha: 26x 5min
Oiii: 30x 5 min
Sii: 24x 5min
Total: 6 hrs 40 mins worth

Spectacular result Sean

Very well done

[AnakChan (Sean)]

Thx Peter! I had banding issues most noticeably in Sii & Oiii which needed a few runs of denoising at various stages to mask it.

That looks spectacular.
You linked to a thumbnail on astrobin though. Can't see the highres.

Well done Sean, as usual.

Whoops! Fixed. Thanks for the pointer on the link! Also decided to do a little more curves, sharpening/blending in PS.
