photography

The method I use for photographing is a long exposure overlay, and I take photos in the remote observatory of Daocheng, Sichuan Province. The telescope I use is the Star Trang RASA11; the camera is the QHY268C; the equatorial Instrument is the Xinda EQ8. I use deepSkyStacker to preprocess the pictures and Pixinsight to carry out linear processing and nonlinear processing.
