Messier Objects
I highly recommend a book on Charles Messier and the creation of this catalogue - Atlas of Messier Objects, 2008 by Ronald Stoyan.
Note: This gallery should be automatically sorted by Messier #.
M83 - NGC5236 - Southern Pinwheel Galaxy - 29/1/2021 (Processed stack)
Imaged from suburban Leeming with the Full Moon in the sky. Main purpose was a test run of the NEQ6 Pro mount's replaced mainboard.
Also an experiment with Light Polution filter. Blue channel background high due to the Moon, so worth a dark sky retry.
