Crescent Nebula from Jurong West

[kochu]

It is very rare to get a whole cloud free night here. Aug 21st presented such a rare one. For the first time in Singapore I managed to image two objects.

Crescent Nebula:
The Crescent Nebula (NGC 6888) is an emission nebula in the constellation Cygnus, about 5000 light-years away.
It is a rather faint object located about 2 degrees SW of Sadr. For most telescopes it requires a UHC or OIII filter to see. Under favourable circumstances a telescope as small as 8cm (with filter) can see its nebulosity. Larger telescopes (20cm or more) reveal the crescent or a Euro sign shape which makes some to call it the "Euro sign nebula".
To me it looks like a "Kidney Nebula".
The faint nebulosity in the background may be the neighbourhood of Gamma Cygni Nebula.

Excellent image, Kochu!

And thanks for the info about the nebula. I've not seen it before and will try next time I'm at a dark sky site.
