Description

"Thor's Helmet" (NGC 2359) is one of my new favorites. Had to capture this at 4:00am until first light this time of year. It is also lower in my southern sky between my house and a big tree.
Used new Celestron C8 XLT with its extra focal length. Thor's Helmet is a perfect target for using SVBony SV220 dual narrowband filter (a "poor man's" Optolong L-Extreme).

~ Captured and stacked using ASIAir Plus
