ASTRO: Sh2- 93 A very small emission nebula

Sh2-93 is also known as LBN146. I can't find much at all on this
emission nebula that is located in the constellation of Vulpecula a
short distance east from SH2-90 I ran in late May. Galaxy map has two
distance measurements for it. One of about 12,000 light years and
another of 8500 light years. It seems to prefer the latter. This is
more in line with nearby SH2-90 they put at about 7800 light years. The
nebula contains the hidden infrared star cluster [BDS2003] 16. The
nebula is said to shine by the light of an 09V star but I'm unable to
determine which one it is. It is [F89b] S93 1 for those with better
catalogs than I have.

Full image is at the native 1" per pixel, enlarged crop at 0.75" per pixel.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Excellent image Rick. Sh2-93 and Sh2-90 look quite similar, the latter being
larger of course.
