Horsehead Nebula in Orion
I finally managed to get some more imaging time on the Horsehead and enough data to make my first ever color image using filters. This is a false(-ish) color image using 3 hours of hydrogen alpha images (Ha) for the red channel, 3 hours of ionized oxygen (OIII) images for the green channel and the blue channel synthesized as a 90%-10% mix of OIII and Ha.
I'm in the process of saving up for a modern CCD camera but in the meantime... Not too bad for a 10 year old camera (Starlight MX716) with a chip the size of a gnat!
Astro-Tech 65EDQ 65mm f/6.5 telescope, Starlight Xpress MX-716 CCD camera, Astronomik H-Alpha and OIII filters, Losmandy G11 mount. Guided using an Orion StarShoot autoguider attached to a 9x50 finderscope and PHD software.
18 x 10 minute integrations (3 hours total time each) for H-Alpha and OIII, 10 x 10 minute darks, 10 x 1/10th second bias frames.
