Location & latitude: 22 miles west of Boston, Ma. 42.3N
Site classification: Suburban
Limiting magnitude (visual): 4 (estimated)4 (est) in vicinity of object
Seeing (1 to 10 - worst-best):  3
Moon up (phase?): Yes, 40%
Weather: Partly cloudy (high veil of cirrus clouds)
Instrument: 16" Newtonian-dob w. 96/99% coatings f/4.59
Magnifications: 143x, 250x,310x
Filters used: UHC
Object: NGC 2371
Constellation: Gemini vicinity
Object data:  Planetary Neb.
This object is very close to the much brighter planetary 
nebula.. NGC 2392, the Eskimo nebula. Although this is 
fairly easily picked out at this aperture, it is much weaker 
than NGC 2392, which has a very high sfc. brightness.
The view with and without the UHC filter was similar, although
I viewed mostly with the UHC as it brought out more contrast. 
This planetary is double lobed, and odd shaped. It is a bit
 larger than 2392, and in fact, is about an arc minute wide.
Best magnification with this high deck of cirrus clouds, and 
poor seeing conditions was at 250x.
Th Eastern part (lobe) of the nebula is triangular, with the base facing 
east, and the point facing west. Then from the south side of this 
triangle runs a bridge, comma shaped, to a round patch of nebulosity 
on the west side of the nebula. This comma shape, 
reminded me of the crescent nebula, but much smaller.
