Here is some combined data from 2019 and 2020 totaling 131 minutes on the barred-spiral galaxy Messier 109 (M109 or NGC 3992) found in the constellation Ursa Major. M109 is about 83 million light years away from Earth and has an apparent magnitude of 10.6. M109 has three satellite galaxies (UGC 6923, UGC 6940 and UGC 6969), all visible in this image, and possibly might have more (ref: Wikipedia). Estimates indicate that this galaxy contains about 1 trillion stars!
