Nice shot. There is sooo much to see in that part of the sky.

So how do you get a C8 at f4.8? A single focal reducer? I am always looking for ways to get wider shots, but my 6.3 focal reducer messes with the flatness. I still use it though. Your shot looks pretty flat.

Welcome back, Jim.
That's an interesting cluster that I wasn't aware of. I'm surprised that it isn't imaged as much, seeing as how it's such a handsome grouping.
Well done.
