Hi,

I decided to take a look at some details in M31 Andromeda galaxy and I found the star cloud NGC 206 interesting. NGC 206 is a star field with nebulosity in Andromeda galaxy. NGC 206 is the richest star cloud in M31, having a total mass of 200,000 suns. I could see why it has its own number. Through the scope, I could imagine it as being a separate object right on the edge of M31 whose spiral arms form a blotchy and discontinuous background. NGC 206 stood out clearly as an elongated patch of moderate, uniform surface brightness with some star like points. I could clearly see its narrowing strip whose tip fades into the spiral arm it lies on. A couple of other fuzzy bright knots, much smaller and fainter, were visible with averted vision in the vicinity.

Fine sketch and interesting object that I never observed. How dark was the sky? NELM or SQM?

Thanks! I'm glad you like my sketch. I'm using a CPC 1100 Celestron. I very good scope. Yes, sometimes the sky is clear here in north, particularly in cold dry air. The VLMag is below 6.0 in zenith. This sketch is done under that dark sky. But as a matter of fact, NGC 206 is a bit too bright in my sketch.

Very nice and detailed sketch! This is a very difficult object to see (in my opinion). Good Job!

Yes it is. You need a dark sky and averted vison.

Well done. :cool: The secret here is dark sky and good transparency.
