Nice. But what is this ??? An NGC object ? Never heard about it.

I've found that its coordinates are RA 9h 39m 53s and Dec +11° 58' 52", so I guess the designation refers to the J2000.0 epoch.

Yes, you're right, Ferenc. I have to say that I wad a bit disappointed because its stated size (Wikipedia) made me believe it would be something like a reasonable planetary. Until I saw that little "star" that wasn't quite a "star".

@Jef: This is what Wikipedia says:
"Forveille et al. 1987 dubbed IRAS 09371+1212 as the "Frosty Leo Nebula" because of their interpretation of the object's extremely unusual far infrared spectrum that water is largely depleted in its gaseous state by ice condensation into grains and for its location in the Leo constellation."
With courtesy to my Italian astronomy friends, here's a map. Happy hunting!

I end up learning more in the Sketching Forums than anywhere else. As a Novice you folks here are very skilled observers as well as artists. Clear Skies

My sketch done at 469x with my 12" dob is attached to this post. FoV is 7', SQM: 21.16 MPSAS, 7°C.
Edit.. oops, I didn't wanted to hijack the thread, so I've removed the attachment because it was automatically displayed in the post, so here's the link instead: this is it

My seeing was terrible too, and to tell the truth, most of the time the picture was blurred, but when we sketch, we're forced to look at an object for a longer time, and that might bring us some moments of rock solid seeing.
And another great benefit of high magnification sketching is that you don't have to mess too much with plotting the field stars.

Really nice deep-sky sketch, thanks for posting it. I have not heard of this object before but it looks like an interesting DSO.
I noticed that you have a binoviewer. Have you used it while observing deep-sky objects? I have tried a binoviewer on some of the brighter DSO's and the veiw can be interesting.
Some year years ago I attended the Texas Star Party and one fellow brought a home-made 20" f/4.5 binocular telescope. The views of the DSO's was amazing, and I felt I was looking at photo's of the DSO's.

I use the Siebert 40mm VP Echelon 2" binoviewer and without OCA (so with shortened truss poles). This binoviewer gives near to equal monocular light throughput. But as always it's a kind of compromise. For a detailed review I'd like to refer to the one I recently wrote for the Cloudynights' review section. Sorry but I'm writing this from my mobile and it's too complicated to add a link here. But I'm sure you'll easily find it.
