Added Dreyer entries
Most of the 50 entries were misidentifications of stars as nebulae by Max Wolf
Corwin was able to confirm most of them from prints of the plates
Sometimes plate defects are involved, but usually Wolf just tried to see moe than was there
Updating formatting
NEXT: Check positions, IDs (Corwin+), add basic pix, captions, tags

IC 2250 (= PGC 1690833)
Discovered (Jan 9, 1901) by
Max Wolf
A magnitude 16.5 spiral galaxy (type SBd? pec) in Cancer (RA 08 16 32.3, Dec +23 37 57)
Historical Identification: Per Dreyer, IC 2250 (Wolf list I #16, 1860 RA 08 08 13, NPD 65 56.7) is "faint, small, diffuse."
Physical Information: Based on a recessional velocity of 3945 km/sec, IC 2250 is about 185 million light-years away. Given that and its apparent size of 0.4 by 0.3 arcmin, it is about 20 thousand light-years across. (Note: Searching for IC 2250 in Wikisky shows the correct object, but with only its PGC designation.)
