Most of you have probably seen the press release for Wolf-Rayet 124 (WR124). Beautiful image. https://www.nasa.gov...de-to-supernova
I looked at WR124, aka Sh2-80, many years ago in the 25" out in west Texas in excellent conditions. In my notes I wrote that the 10th mag "central star" (Megastar has this plotted as a planetary nebula) was easy to find but the nebula had to be teased out. I wrote that the H-Beta filter showed it best. Just a soft roundish glow about 1' in diameter. No detail.
Here is an excerpt penned by Uwe Glahn over in the Deep Sky Forum (2012):
"Last new moon I tried the WR Nebula Sh 2-80 "Merrill's Star". The nebula is called after Paul Merill, who wrote about the star first at 1938, after Cora Burwill detected an emission line in the yellow portion of the spectrum through the objective prism spectogram on Mount Wilson. It was misclassified as a PN (Min 1-67; PN G050.1+03.3 )
After I few unsuccessful observation I could see something around the 10mag star WR 124. I observed with my 27" under good to very good transparency and tried several AP's and filter. The only successful combination was 172x (AP 4mm) with Hß filter. With that I could see a very dim, round glow with approx 1' in diameter. Brightest part was like a semicircle structure just S of the star. Another better defined part lies very close just E of the star with a short part to the NW.
What experience do you have with this unusual nebula? What aperture is needed to see the faint glow?"
Anyway, this one goes back on my observing list for the upcoming spring season. I'll take a look at TSP.
