Hi,
Here’s the Horsehead Nebula taken over the last few weeks (thanks drought) with a 18cm f2.8 Takahashi Epsilon Newtonian and SBIG STL11000M CCD. 18 x 10 minute Clear, 15 x 10 minute Ha, 6 x Green and Blue, 1x1 bin. –20C.
I calibrated, applied Cosmetic Correction, Star Alignment, and Image Integration In PixInsight. I then did the processing in Photoshop. I’m slowly working through Warren Keller’s Inside excellent PixInsight book – I have yet to work through the processing chapters! -
