HOO + RGB integration begins.
In reality, the integration includes sessions with different exposures and temperatures, and I didn’t go into the details.
Processing by Evgeny Sergeev.
In fact, his work on this nebula (https://deepskyhosting.com/NOQ5L66) originally inspired me to reshoot the Dumbbell Nebula and aim for a similar result. However, I made quite a few mistakes during shooting, and the mount sometimes didn’t cooperate. So the result could be improved in terms of detail.

A bit over-sharpened the stars, looks awesome!)

You just haven't seen them in their original form. They're simply awful there!)

A very beautiful butterfly—calling it a "dumbbell" doesn't do justice to the intricate detail in its wings :)

They named it when they visualized it.

Honestly, the most beautiful photo of the Dumbbell Nebula I've ever seen!))

The absolute best only among ours) I remember Fatalik had a good one. Need to find it and compare.

https://deepskyhosting.com/Fg64wxV shows a bit more detail, but it has three times the total exposure time.

Well, the integration time is longer after all. But honestly, I never imagined it looked like yours until now. Now I'm even thinking of capturing it myself.

Good luck! With a dual-band filter on a color camera, you can achieve a very similar result.

Interesting and charming! A second perpendicular dumbbell (to the first dumbbell, the "stub") appeared — usually it's not visible.

This is already some kind of butterfly.

Basically, there are already three dumbbells there, and one without a weight set on one side.

We need to classify them: outer dumbbell, inner dumbbell, stub. I just finished my "dumbbell" — there's only a faint hint of the "outer" part (4 hours R-G-B, f/6.5). I think narrowband filters are needed.
