Ptolemy's Cluster

[andyc (Andy)]

OK, this was fun! 13 x 5 minutes on M7 last night, and just a staggering number of background stars to hide the noise from a slight lack of exposures. There's also some other hidden gems, including the globular cluster NGC6453, dark nebula Barnard 287, scattered open cluster Trumpler 30 and little blue planetary nebula Hoffleit 2-1.

Hope you enjoy the view.

Very nice version with 60d
I just wonder whether 60da would add any extra “juice”

Nice image Andy. Great field.
That sure is a small PN.

Nice work, Andy!

That looks great Andy. Getting a nice golden colour on the background stars has been difficult in my experience. Yours looks very good.

Well done, great separation of the cluster from the background. Reckon the colour is a bit cyan on my monitor - might benefit from warming it up a bit

Excellent...golden star fields look so magic

A beautiful photo Andy.

Sharp and well composed.

I love the golden colour.

Thanks everyone for the kind comments, glad you liked it!

Ian, it's a good question (if the 60Da would do better than the 60D) - I'm not sure there's very much H-alpha in this region, so I would guess not, but I'm sure the better imagers could say otherwise!

Andy, I'll have a go warming it up - colour calibration without a clear white or black point is tricky so you could easily be right!

Though I do like the Sidonio approach to colour saturation
