The Tulip Nebula (Sh2-101) in LHaGB - a photo on Flickriver

The Tulip Nebula (Sh2-101) in LHaGB

I already have an image of this nebula using just the 656 nm red light from ionized hydrogen: flic.kr/p/2mcJ4iK

There's lots of detail there, but with such a rich starfield, I wanted to bring color into the image. I shot L, G, and B channel data on 2023-07-17, registered it with the original H-alpha data, and was able to cook up this version.

This was also shot with the Atik 414-EX on a Celestron Edge HD 925 at 1530 mm focal length.

L: 120 20 s frames
B: 60 30 s frames
G: 60 30 s frames

I also shot 20 2 min exposures with H-alpha, because, why not? These were combined with the previous data in this channel.

Subframes captured with N.I.N.A. Preprocessing in Nebulosity; registration, stacking, channel combination, and initial processing in PixInsight; a small touch up with Topaz Labs to finish.

I see a lot of renderings of this nebula where the stars are removed or greatly diminished. It lies right along the band of the Milky Way in the sky. I choose to include the stars that give context to how rich this part of the sky in Cygnus is.
