M46 and NGC2438

Hi Everyone,

I've been clouded out for over 6 weeks, but last night there was a 4 hour window of "clear" but unsteady skies. I decided to shoot something that would be quick. I chose M46 in Puppis.

Even though the transparency was poor and the ski area lights were on I think it turned out pretty well. The planetary nebula NGC2438 stands out nicely.

Very nice, Tom! I think it came out great given the circumstances.

Nice, Tom! The planetary really pops out nicely.

Thanks. I like how the star colors turned out -- M46 stars are blue while the galactic background stars are orange-yellow. Interesting isn't it.

Nice image Thomas! It is a haunting object and the star colors are lovely.

Excellent shot Thomas!
You know, I've never hunted this nebula... I must se it the next time I get the scope outside...


Thanks for sharing! 8)

Very very nice.

One question. I see some blue halos around the stars. I get the same with my FS152. I was not sure if it was the scope or the camera. I then shot the same target with my RCOS 12.5 inch same camera. Sharp stars with no blue halo. Is this the point where refractors start to lose ground to RC style scopes or is the another explanation? What I did was hardly a scientific comparison.

Cheers,

Greg.
