Sky simulator for Ascom & Alpaca & Indi

Sky Simulator for ASCOM, Alpaca and Indi is a software program designed to simulate an astronomical camera mounted on a computer-controlled telescope. The camera displays images of the night sky based on the telescope pointing-at position and is affected by exposure time and focuser position. The images can be created artificially or using the online deep sky survey. It simulates also a guide camera. mount, focuser and camera rotator if required. You can also use your own mount in the simulation. Simulation of mount polar alignment errors and mount periodic errors is possible. This simulator is a useful tool for testing the focuser routine, astrometric solving, guiding and test run sequences. Star and a deep sky databases are included. For questions, problems, suggestion visit the forum. Ascom installation required. Install instructions for CCDCiel, APT and Nina : https://sky-simulator.sourceforge.io
