Sh2-200 a.k.a. HDW 2

[Petergoodhew]

Sharpless 200, also known as HDW 2 (Hartl-Dengl-Weinberger 2) and commonly known as the Bearclaw Nebula is a very faint planetary nebula in the constellation of Cassiopeia. The Ha signal is much fainter than the OIII so I went extra deep on the Ha capture.

Astrodon Blue: 20x300" bin 1x1
Astrodon Green: 10x300" and 10x600" bin 1x1
Astrodon Lum: 37x600" bin 1x1
Astrodon Red: 20x300" bin 1x1
Astrodon Ha 5nm 62x1800" bin 1x1

Total Integration: 61.5 hours

Captured on my dual rig in Spain.

Good grief, that deep!  I don't think I've done over 60 hours of imaging in total in my life (so far.)

Never seen this looking so good.  Hats off!  Chapeau! ... plus whatever the Spanish equivalent is.

Not sure why it's called the Bearclaw Nebula, but it's an amazing-looking thing nonetheless.  Very impressive.

I think it's because it's not usually imaged as well and deeply as this so most images only show the top half making it look more like claws, Cf Cats Paw Nebula the trouble with " common " names.

Very impressive image..

Another quality image of an unusual target. You really have gone deep on this one.

I imaged this object myself last year and my effort pales next to your image. Especially the outer ha nebulosity is ultra faint. Hats off! It's a superb shot!
