What nebulae do you know in Cygnus? The reply to this question will probably be the Veil, the Crescent, The North America/Pelican, the Blinking... and perhaps some more obscure ones like the Embryo or the Cheeseburger. Now how about this one? Yes, I'd say that NGC6857 is not the easiest and rather reserved for scopes with a considerable aperture. But personally I think it's a beauty. The OIII filter doesn't really help on this one since it's one of the rarer nebulae which predominantly emit in the H-Beta spectrum. But with an UHC or H-Beta filter it should be doable as from an aperture of 8" or so (and under decent sky conditions). Since I don't have any of these filters in the 2" size, I made this drawing without. On the other hand, it was quite interesting because I could see a lot of "background nebulosity" caused by the bright Cygnus milky way arm. Really exciting as I thought I could almost resolve the Milky Way into tiny little stars, but then again just not. Hopefully this sensation shows well in the drawing...

EDIT: What a wonderful evening I had yesterday, observing while hundreds of fireflies danced about in the surrounding field... :D

Peter,

This is very nice. I have never looked at this one.
Summer nights with the fireflies is a big part of summer nights to me.
One of the attendees at our Friday night star party commented, " I wonder what magnitude fireflies flash at." ;0

Frank :)

hi Peter,

You caught an interesting object.
I saw it at first last year with my 16" Dobson.
Good work & nice sketch!

Bye

A beautiful sketch like this makes me forget the Belgian clouds for some time :)

Thank you very much Tom, Christian, Ken and Jef! I have to admit that I didn't know this one myself until two days ago. But whereas a lot of Dobson-purists loathe any form of automisation and argue that a true Dobson-observer should always look the objects up himself the old-fashioned way, I tend to disagree. Not only does a Sky Commander or similar push-to finder save you a lot of valuable observing time, it also teaches you a lot of gems which have been forgotten by others. And this is a good example... :D

Very nice sketch. And, I agree with Peter about the Sky Commander....saves hours of time finding things so I can sketch.

Thanks, Tamás!

I've found out that you only live about a 7h drive away (well... "only"... :D ) I hope we get the opportunity to see each other some day!
