Description:
Observed Hickson 50 last night. I have seen all 5 components in a 36" with
Larry Mitchell.
This observation was with my 20". Hickson 50 A was the only galaxy visible
with careful study. I believe it is much brighter than the published
magnitude in the Hickson Catalogue, which is 18.4. My estimated visual
magnitude of this galaxy based on comparison of other faint galaxies is
approximately 17.2.
