Will the real NGC 2363 please stand up? For years, there has been an ongoing debate over the true identity of the 2,363rd entry in the New General Catalog.

Observed the pair January 4, 2019; SQM-L 21.38, clear and still.

 

Large H-II region in SW NGC2366 dominated the view. Triangulation using that feature and faint optical dbl *'s NW of N2366 core located N2363 S of and ~in-line with the dbl *'s. N2363 is due W of the bright HII knot in N2366 and is faint and diffuse though not small. N2366 was large, not so faint, V elongated, not concentrated and dominated by the bright H-II region (Mrk 71).

 

This observation was a lot of fun.

Nice writeup. I observed NGC2366 in 110mm refractor. NGC2363 was out of reach, however NGC2366 was quite interesting. In the beginning, I saw only the bright H-II region, which looked from time to time like a misty double star. The faint body of NGC2366 was quite a challenge. The elongated misty thin line started to appear with more time spent at the eyepiece and with quite concentrated averted vision,
