Messier 46 (M46 or NGC 2437) is a bright open cluster approximately 5,500 light-years away in Puppis.

 

NGC 2438 is the planetary nebula right above M46. It is located approximately, 3,000 light-years away. It is illuminated by an estimated 17.7 magnitude central star.

 

Luminance – 12x600s – 120 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

 

240 minutes total exposure – 4 hours

 

Imaged March 12th, 13th, 24th and 25th, 2016 from Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

Excellent.... especially like the wide field image from your refractor.  There is another PN in the refractor shot.
