 IC 2118 "Witch Head Nebula" Cropped image from Sky-Watcher Quattro 250P Newtonian telescope IC 2118 "Witch Head Nebula" is an extremely faint reflection nebula believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel in the constellation of Orion. This is a joint project of James Foster and me using a 10-inch f/4 Newtonian telescope at Frazier Park California. file: WitchHead-JRF10NewtFB-1x1c-cr.jpg Photographic Data telescope: Sky-Watcher Quattro 250P, 10-inch f/4 Newtonian telescope with coma corrector (aperture 10-inch, f/4, FL= 1,000 mm) mount and guiding Astro-Physics 1200 GTO imaging camera: ZWO ASI2600MM-Pro color astro-camera filters: Red, Green, Blue exposure: Red 300 sec X 15, Green 300 sec X 15, Blue 300 sec X 16 Total Exposure time is 230 minutes (3.8 hours) guiding: off-axis processing Aquired and stacked by James Foster with Maxim DL.
