Jon Talbot captured this unreal image of StDr 55 (Strottner-Drechsler 55) using his SVX152T. StDr 55 is a planetary nebula candidate discovered by Xavier Strottner and Marcel Drechsler in June 2020. It’s approximately 5 arc minutes in size and is located in the constellation Cassiopeia. The entire area is dominated by red hydrogen emission with a small amount of oxygen emission near the bright nebula in the upper left corner. 

According to Jon:

"This image is the first deep color image of StDr 55. In the main wide field image, StDr 55 isn't easy to pick out, but it is near center and looks like a slightly brighter area of emission with finger like extensions. Several other interesting objects are within the field of view and are highlighted below. Lastly, in the full image, on the extreme right, near the center edge, is the small 33" planetary nebula IPHASX J012507.9+635652."
