IC2149 – Planetary Nebula in Auriga new
      #5521718 - 11/15/12 06:48 PM Attachment (88 downloads)

This is another target that I first located with my LightBridge 16. IC2149 lies about ½ degree northwest of Pi Auriga (Menkalinan). It is fairly bright (Mv 10.6) and easy to find but it’s really small and at first it just looks like a star. In fact, it was cataloged as a star until 1906 when its spectrum was found to show the bright emission lines of H-alpha and O-III associated with a planetary nebula. High magnification shows a bright little peanut shaped nebula with a stellar core. Photographically it looks like a tiny version of the Saturn Nebula.

This is the original full frame showing the location of IC2149 and selected stars labeled.

I have tried to see that object. It is rather easy to find in Auriga, but I have never seen it. I tried to see it in white zone sky.

This interesting planetary has very high surface brightness and will be visible in a white zone, by cranking up the magnification on your scope to the max - and then some. And it will need ultra-über-high magnification to tease out the details, but then they can be seen in a surprisingly small telescope. Here's a drawing of it I made with a 94/1300mm refractor at 742x:

I've never seen this object. You've inspired me to look at it! I'll report back here with a drawing!

Thanks for the inspiration!

Cheers,

Sorry - cannot access my gallery at the moment. Will update shortly.

I will try again. I usually do not use the highest power I have of 406x as the seeing has to be good.

WOW! Using over 700x on a 90mm scope...your skies must be incredible at times!

They are. Sometimes they are just super incredible SQM 21.8 with 0.5" seeing and I think "why do I ever think of moving away?", but then follow three weeks with 100% cloud cover, followed by half an hour of incredible skies, but miserable seeing, then another two weeks of near 100% clouds, then two nights of hazy skies, then clouds again...

But when my skies rock, they *really* rock. I just wish they would come on stage a bit more often...


Clear skies!

I've seen IC 2149 through a 10" Dob at my yellow zone site.
