Corwin's Notes

===== NGC 7283. Found by Marth, there is nothing near his unverified position aside from a double star about two arcmin preceding. It's possible that he saw CGCG 452-017 a minute of time following his published position, but it would also be 2.5 arcmin north. I'm leaning toward the smaller positional error, but do not want to insist on the double. So, both objects are listed in the main table. ----- Coming across this again in April 2013, I wondered why I had not checked for other objects that Marth might have found on the night of 8 August 1864 (give or take a day; Marth has the discovery date listed as "1864.60"). This was a productive night (or 2, or 3) -- Marth found 24 objects during his sweeps. Aside from this object (and NGC 7350/53, which see), his positions are very good with no significant offsets in either RA or Dec, and standard deviations of only 0.4 arcminutes in RA and 0.9 arcminutes in Dec. So, Marth's position for this object may well have been the result of a blunder of some sort. However, aside from the galaxy and double star I noted earlier, I don't see any other reasonable candidates. There is nothing north or south at decimal offsets (+- 1, 2, or 10 degrees), nor it there anything east or west at +- 1, 2, 5, or 10 minutes of time. So, this is still a bit of a mystery.

Steve's Notes

===== NGC 7283 17.5" (8/20/88): extremely faint, very small, round, weak concentration. Located 2.7' E of a mag 10 star and 19' NNE of NGC 7290. This galaxy is 1.0 min of RA preceding and 2' S of Marth's position, so the identification is very uncertain.
