There is a quadrant reversal. Using the old BD catalog numbers (BD +31 1887p and
1887s), the 1894 measure is correct. But the new magnitudes (from the Delta Magnitude
system) show that 1887s is brighter than 1887p (as shown in the Magnitude fields here),
so the 1991 measure is correct.

Type: Gal
Surface brightness: 12.9

Dimensions: 9' x 1'
Magnitude: 10.6
PA: 44
Notes:
NGC 2683 was discovered by William Herschel on February 5, 1788.
This spiral galaxy is viewed nearly edge-on from our perspective. Because of its
appearance, it was nicknamed the "UFO Galaxy" by the Astronaut Memorial Planetarium
and Observatory site.
[Source: http://www.seds.org/~spider/spider/Misc/n2683.html]
Observations:
C8 at 65x. It presents a very pronounced NE to SW streak, with high surface
brightness. It takes high powers very well, where it shows a dust lane on the S side. A
12m star lies 3 min S and a 6.3m one (SAO 61074) 28 min W.
C11 at 115x. Large, bright and even, but no sharp nucleus.
