Sky simulator for ASCOM released.

Recommended Posts

For those who are interested, I have released a free sky simulator for ASCOM. This program can be used to test your (Windows) image capturing program, test sequences, test centering using plate solving, test the focusing tool, for demonstrations  or for software  development.  For the sky simulation it uses either online deepsky survey images or a build-in planetarium program.

Download and forum:  https://sourceforge.net/projects/sky-simulator/

Feedback is welcome.

Sky simulator for ASCOM using online DSS images or an artificial sky. The camera simulator will show a "deep sky survey" or artificial image based on the mount and focuser position. The image will be blurred/defocused based on the focuser position. In imaging programs CCDCiel/NINA/APT/SGP you should select the camera "Sky Simulator" and the mount "Telescope Simulator for .NET". The program will download images and feed the camera simulator with these. Set the image size in "Sky Simulator" the same as in the program. And select as image file documents\image.jpg. With this simulator you can test focuser routine, centering using plate solving and sequences.

FYI, the ASCOM Sky simulator version 1.8 has been released. The default star database goes now up to magnitude 14.  Improved artificial stars.  Deepsky labels can be switched off.  The image dimensions are now set at one place in the program.

That could be an option but will require some significant amount of work. Interface should be INDI. There is already an existing INDI sky simulator using the GSC star catalog, but I have never tried it.  Is there something to improve?

Note that I just fixed a small problem with the "go default" button and it is just uploaded as Sky simulator 1.9.
