Image Specs

Due to its enormous size a wide field fast focal ratio telescope was used to capture these 2 beautiful nebulae. - the Esprit 100ED f/5.5 on a Losmandy G11 equatorial mount.

The image was framed over 2 panels side by side with a small overlap to allow stitching reference. Each panel is comprised of 30 frames at 220 seconds per frame. Calibration dark and flat frames were added (50 in total per panel) to remove noise. All frames were then stacked/aligned and finally stitched together to form the entire image. The Optolong L-Extreme narrow band filter was used to capture the Hydrogen Alpha and Oxygen III spectra emitted by the nebula. A OSC cooled QHY 168C camera, dialled down to minus 10 degrees C to reduce thermal noise, Post processed with Affinity Photo.
