Here is the first image processed from last night. This is 18% of original size.

Canon 300D with 2 x Barlow (DOH!), ISO 1600, 15 x 20 seconds.

I made a mistake on all the images that I took last night - I left the barlow in place. So...

one I have a smaller FOV than I would normally have had,

two the star trailing was preventing me from doing more than about 45 seconds

three, there is little flaring towards the other edges of the image - this has been greatly reduced by the resizing though.

All in All very happy with this one. There is a lovely orange star right in the centre - which makes a great contrast to the other stars...

Hope you enjoy

It's a very nice little cluster that one. I've ever actually seen it before - it doesn't show up too well in the finder - but I was lucky in that the first test image that I took showed it and I could centre it really easy...

Very nice indeed Ant. You've really captured that nicely, and the colours are awesome. Nice 20sec subs as well.

I must admit it looked a very nice little cluster in the eyepiece. One for next time.

I wouldn't say little is known about it, James. A quick search comes up with a few interesting facts. It's also known as SAO 11826, is mentioned in 28 scientific papers dating from the 1800's to 2004. It's an M type super giant and has an eclipsing companion. And that's just a quick look, and searching under the SAO number.
