IC1284 / NGC6589 / NGC6590 in Sagittarius
with 10" f/3.9 Astrograph
Uploaded 9/9/23

 
Here
            is a very deep 8 hour integration time centered on NGC6589/90
            and IC1284 which took nearly every clear night in July here in
            Arizona to collect the data on. (Its rainy season). I was surprised
            how much glowing hydrogen fills the entire field in this part
            of the sky. M24 is to the upper right corner, and contains Sharpless
            2-43 which is an integral cloud of glowing red hydrogen. The
            red glow on the lower right is Sharpless 2-35 and the big patch
            of nebulosity to the upper left of IC1284 is Sharpless 2-37.
            What an amazing field! Technical Data: 10" f/3.9 GSO astrograph
            + Baader MPCC, Atik 16200 CCD, 8 hours total integration time,
            Payson Arizona.
