Here is my sketch of NGC 281
I sketched it at Mt.Kobua star party seeing was ok and the transparency was good.Darkness was abut mag 6.5
I used my 15" scope with a 20mm Nagler and an O-III filter.

Excellent capture of NGC 281 and IC 1590 here. Love your varying tones of the nebula and you've captured its shape very well. Thank you for sharing it.

John,

An excellent observation of NGC 281 (Pacman Nebula) in Cassiopeia. You have captured this interesting nebula (H II region) very nicely. It contains Bok globules (which over time may contract into stars), IC 1590 (an open cluster), and HD5005 (a multiple star). Thank you for sharing it with us all.

I took the liberty, if I may, to invert your fine observation, adjust levels, and place it upon a dark background. I hope that you like it.

I look forward to your future observations.

John,

Sketch looks very nice. You captured fine detail visually and with the adjustment by Carlos to the inverted eyepiece view you can see it each way.

Excellent!

Frank :)

John,
Well done! The 15" really makes this faint nebula stand out.
Nice rendering.

I have to agree with Carlos. The inverted sketch is even more impressive.

Here is my Take on the negative of this sketch.I added the slight green effect to simulate what the O-III added.

John,

I like your version even better as it simulates what you noted at the eyepiece field. The only thing that I would suggest is to place the observation on a dark background which will bring out the nebula even more. I have attached the dark background version below. I hope that you like it.

Thanks Carlos,That does help bring it closer to what the eyepiece field shows.

Nice sketch! I'm in the process of saving for an O-III filter for my 10" now that I've seen what one can do to nebulas.
