The Baby Dumbbell Nebula HU 1-2

 

A few weeks ago I discovered ... well okay, I did read about the Dumbbell Nebula and that there are 2 other "Dumbbells": the Little Dumbbell (M76) .... and the Baby Dumbbell (Hu 1-2 , PN G086.5-08.8, PK 086-08.1, ARO 89).

This one is almost never captured, so of course had to try it (I am a sucker for underdogs) with first light of my Meade LX200 8" ACF OTA.

Also a challenge because my Zwo ASI294MC Pro is send to Zwo to check, so I did this with the ASI385MC which has no cooling and a way smaller FOV. This capture is uncropped 13.7 x 7.76 arcmin and has 0.425 arcsec/pixel.
Collimation of the LX200 was just great: only had to do 2 tiny adjustments. Still obvious room for improvement but I just had to do this first light because: clear skies smile.gif
And the scope really is an improvement over the LX65 8" ACF: focussing is better, of course the mirror lock is cool and the optics are even better from what I can see now with the ASI385MC.

 

The Baby Dumbbell Nebula is a planetary nebula and is rather unknown, it has no NGC or IC number. Because of that, it's almost never captured.
It is fairly bright (mag 12) and rather easy to find as a small blob with a 6" scope or bigger in Cygnus. The sort of X-shape is clear to be seen but it has almost no color.

The inner part is 15 arcsec and with the arms it's around 25 arcsecs. The structure itself has a kind of fuzzy cloud-like appearance, but this is only visible with a > 20" scope or the HST. It is at 9900 light years and was discovered in 1920.

Thanks!

And yes, the Ioptron CEM25EC is just amazing: I tested it with 5 minutes unguided exposures under f/10 and it's even able to track that good. But for me it's max 3 minutes due to my Bortle 7/8 skies here.

Thank you!
And yes, I love these kind of objects. The splendor of the big boys and girls is of course marvelous but the "smaller" ones are more my cup of tea somehow.

Wonderful result and that with Bortle 7/8, well done.

That sure is a little object!

 

Stay well,

Mert

It is small but at the same time it isn't: it's around the same size as Mars now.
And yes, despite my Bortle class here I can capture rather good. My most faint object is magnitude 20, a cluster in Andromeda. It's barely showing, but it's there. I blame the excellent optics of the scope :)
