This edge-on spiral galaxy is located in the southern constellation of Indus. It is about 31 million light years from us, and was first observed by John Herschel on the 4th of October 1834.

It has an apparent magnitude of 10.51 and an angular extent of 8.15 X 1.63 arcmin. I love looking for all the other objects far off in the distance. The halo reminds me of a fish with the tail at the base flaring out, and the head at the top.

Another nice galaxy imge Terry ...a good start, just under 200 Billion to go

The shape reminds me of the Titanic actually, as it is on the sea floor, ie without smokestacks ..

Thanks Mike. A lot of these far-off targets have great shapes. They are just too far away with our tiny telescopes

Very nice image Terry! A small target but good definition and colour. That RCOS is a sweet scope for sure!

Cheers Marc. I love shooting these small targets. A larger scope would help with these small targets for sure.
