Hello everyone.
A few days ago I posted NGC 7129 on the forum, but since then I have been getting data for the second panel to include the gorgeous open cluster NGC 7142. These two really complement one another I think.
There is an interesting if not rather odd band of Ha that almost seperates the two, so I got a couple hours Ha also to bring that out a little more.

So exposure times are HaLRGB of 9.5:13.5:6:6.5:6 hours for a total of 41.5 hours. Taken with the 17" CDK and U16M.
I hope you like it.
cheers
Martin
