Witch Head Nebula
Witch Head Nebula
IC 2118 (also known as Witch Head Nebula due to its shape) 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. The nebula lies in the Eridanus Constellation, about 900 light-years from Earth. The nature of the dust particles, reflecting blue light better than red, is a factor in giving the Witch Head its blue color. Radio observations show substantial carbon monoxide emission throughout parts of IC 2118, an indicator of the presence of molecular clouds and star formation in the nebula. In fact candidates for pre-main sequence stars and some classic T Tauri stars have been found deep within the nebula (wikipedia).

Very nice processing! Great image. I do have a question for you if you don't mind. I see you use PixInsight to process, as do I. However, I am having trouble with the cal.fits files TL is now using. I've been told to use Image Solver, then WBPP. So I try that, but it takes forever (9 hours to Image Solve a set!) and I have a very robust and fast computer with CUDA enabled. Then WBPP is also very slow. So I ask you, how do you handle the cal.fits files? I hope you answer! Thank you, Leslie
Thanks, my downloaded files from TL are ok, I had no problems regarding speed in WBPP. I think you should check the WBPP settings again.
