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.
