Sanduleak 2-21 is a planetary nebula in Puppis; magnitude:13.69 ;size:36"x42" ; fairly large but faint, 4.5 magnitude star nearby interferes with view; OIII filter is needed and works well, I used a 10mm Ethos at 158x magnification with my14.5 Starstructure Dob f/4.3

Raul,

 

This is a very nice looking sketch of the planetary nebula and its environs.

Nice post.

 

Frank :)

Great sketch.  Thanks for sharing because I could not see this from my normal skies.

Raul, you are going deep and giving me aperture fever. Don't stop! I got a kick about the diffraction spikes on your mag 4 star, I am not sure I see them. Of course much dimmer in my 8", just like the planetary you sketched. Nicely done.
