Messier 46 is a great open cluster to view with just about any aperture, but if you have some decent skies and patience, try to view the embedded planetary nebula NGC 2438. I have viewed it before in my 8" SCT, but don't recall if I have in my 6" Dob. Either way, give it a try, because its very cool to view 2 separate types of objects within the same field of view! Here is my live capture of Messier 46, and you can clearly see NGC 2438 and its subtle colors in the screen grab below.Messier 46 and NGC 2438Specs of our capture above:M 46 - NGC 2437 - Cr 159 - Mel 75Type: open star cluster (III2m)Magnitude: 6.10 (reduced to 6.31 by 1.50 Airmasses)RA/Dec (J2000.0): 7h41m46.08s/-14°48'36.0"IAU Constellation: PupSize: +0°20'00.01"Distance: 1.700 kpc (5545.4 ly)(From Stellarium)Telescope - Explore Scientific 8" f3.9 Newtonian with a Baader MPCCCamera - ZWO ASI294mc ProCapture Software - SharpcapFilter - Baader Moonglow/SkyFilterExposures - 15 x 30 secondsOur view above was a live shot (no post-processing) via Sharpcap, our main software currently for EAO (Electronically Assisted Observing).
