M8-M20 two part panorama
with NEXUS coma corrector
with 10" f/3.9 Astrograph @ f/2.9
Uploaded 9/15/24

 
The
            incredible richness of the background nebulosity in this field
            is punctuated with the Trifid at the top and the Lagoon nebula
            at the bottom. This two part mosaic was taken with my 10 inch
            and a Nexus Coma corrector. That splashy open cluster at the
            top is M21 and note how the blue reflection component around
            M20 is quite extensive. Technical Data: 12.8 hours integration,
            10" f/2.8 GSO Newtonian, Atik 16200 CCD, Payson Az.
