Corwin's Notes
=====
NGC 2316 and NGC 2317. This was seen by both WH and JH, but neither noted it
as a double nebula. That was left to LdR (or his observer at the time, Bindon
Stoney) on 20 Feb 1851, who described this as a "S close D neb below [that is,
north of] 3 sts, 2 stellar points (or nuclei?)". He has left us a reasonably
good sketch (nicely reproduced in the 1861 monograph) that matches the sky
reasonably well. The double "nuclei" are best seen on the POSS red and blue
images, and it is from those that I estimated the positions. The positions
I've adopted from the 2MASS PSC are probably for these same knots.

NGC 2316
13.1" (2/25/84): moderately bright nebulosity, small, possibly surrounds two stars. Located just 1' S is an obtuse triangle of mag 12 stars. Enhanced with a Deep Sky filter.
