NGC 6888 Crescent in HOO

#1

Post by KathyNS »

This is my first attempt at binning the Oiii to reduce exposure times and increase SNR. It worked well, and the Oiii signal was well balanced with the Ha, requiring minimal tweaking. Stars are RGB from an older image.

Very well done. You picked up some of the faint nebulosity at the head of the crescent.

Very nice Kathy.
Stars are RGB from an older image.
It's handy when you have been imaging long enough to do that. I quite often these days pinch data off an old image. Or even combine the 2 together for long integration if the FOV is the same or similar.
