CrescentNebula_EON130T_300.00s_AllFilters
Image of the Crescent Nebula (NGC6888), about 5000 light years away. Taken with an Orion EON 130mm triplet with field flattener, using a QHY168C 14-bit color camera, and a 48mm diameter OptoLong Quad pass filter in front of the camera. This is a combination of different filter stacks, each of many 300 sec exposures from backyard Sunnyvale California location. Scope was mounted on a Losmandy G11 mount, and using a Celestron 80mm piggyback scope with ASI178MM video camera and PHD2 for autoguiding. Final image integration and denoising were done in Affinity Photo.
