Last night is was clear so I was looking for planetary nebula to image. This was in perfect position for me to image. It is quite small even for my 9.25 scope so it is cropped considerably. This isn't imaged that much so I gave it a try. I used the Celestron 9.25 w/0.7 reducer. Asi 1600mm, and took 10-360 sec. Hydrogen Alpha subs and 7-360 sec O3 subs
This is the info from Wikipedia "NGC 4361's central star is an extremely hot [WC] star. Its temperature is at 270,000 K,[4] hotter than every Wolf–Rayet star known. It is nearly 18,000 times brighter than the sun, but is only 6.1% its size. This star is only 1,230 years old."
