melachrino Use Stellarium for Windows, both the stand alone program and the browser based version are free and miles above anything SkyAtlas can do, it's not even funny when you start comparing the two. I only use SkyAtlas for the final manual GoTo step and triggering the image capture, I do everything else in Stellarium. If I could control the S50 from Stellarium (it works with other GoTo telescopes but not the S50) I would have absolutely no need for SkyAtlas.
