Description

First time targeting IC 4592, the Blue Horsehead Nebula, all by itself rather than part of a larger field. This reflection nebula in Scorpius is extremely faint and low to the horizon at my latitude, so I was pleased to be able to pull out some decent detail and color. I used a stock Fujifilm X-T10 camera and Samyang 135mm f/2 lens wide open, shooting 53 2-minute tracked exposures (1 hr, 46 min total) at ISO 1600 and no calibration frames. I stacked the images in Deep Sky Stacker and processed the stacked image in Astro Pixel Processor and Photoshop. The final image is cropped in a bit from the original frame. Tracking (no guiding) was provided by an Orion Sirius EQ-G mount.
