NGC 7293 the Helix Nebula
This image of NGC 7293, the Helix Nebula, was taken at a Bortle 4 site in Landers, CA, USA on a New Moon night. Telescope: Explore Scientific ED102 FL 714mm F7. Guiding was with Orion 50mm Guide Scope FL 242mm with a ZWO ASI290MC for the guide camera. PHD2 auto-guiding software used the guide camera output to precisely guide the mount as the stars marched across the heavens. Mount: Celestron Advanced VX. Main imaging camera: ASI294MC PRO cooled to -5C. Exposures: 22 x 240s with Gain at 120 and Bin 2 x 2. No darks, flats or bias frames. Sequence acquisition was through Astrophotography Tool (APT) software. The images were aligned and processed to a TIF image in PixInsight software. Then the final image was translated to JPG format in Photoshop Creative Cloud software prior to uploading. The image has been moderately cropped. Polar alignment was with SharpCap Pro.
