Object of the Week, January 30, 2023 – Simeis 22 / Sh2-188

[Ciel Extreme]

I have an observation from September 15, 2014 from my backyard, using an 18" f/4.5 reflector at 207x, no filter used. Seeing was 6/10 and the NELM was 6.0:

“This nebula is extremely faint and very difficult but the sketch agrees well with the DSS image. Appears as a very hazy and indistinct, crescent-shaped glow involving five faint field stars near the western terminus of the nebula. The nebula curves from the ENE to the west; about 7x1 arc minutes in size.”
