Description

While working on my Messier list M21 came up. It was just out of frame on my previous Lagoon, Trifid shot so I pointed the 8" edge at M21 just planning to do a short run for my list. Actually in the 8" Edge M21 didn't look like much so I re-framed for the wide-field 60ED. NGC 6544 was a bonus.

This is my first post using the ASI 290 Mini/Celestron OAG with the 8" Edge as the guide scope. Yes, that's a bit of over kill for the 60ED. Almost all my stars came out square. This is a 2X Drizzle down-sampled in PS. Probably should have done a 3X drizzle, some of the smaller stars are still square!
