The RA on the meridian at 6 pm on the 21st of the month is equal to the month number times two.
At 8 pm RA = 2M + 2 e.g. For Jan, RA = 2x1+2 = 4 at 8 pm (approx.) At 4 am RA = 2M + 10 e.g. For Jan, RA = 2x1+10 = 12 at 4 amOC is open cluster, GC is globular cluster, DN is diffuse nebulae, PN is planetary nebulae, Gal is galaxy.
Sizes are in arcminutes.
"Nearby objects" lists some interesting objects within 7 degrees of the main object. These are sometimes very faint.
