Dear, I'm facing software issues with original SteadyStar software and as I know that Maxim DL could drive it, could you tell me which release/option (various prices from 199 to 599!) I need to buy ? OK before I will try the 30 days demo... hoping have enough good sky to test... but is someone know if this product work fine with various guiding camera (original work only with Starshoot Autoguider that has poor performance), and I want to use DMK or Watec with grabber... because it is difficult to find a bright guiding star with more than 3m focal length... for more than 10 correction per second... Thank in advance for your answer. Mathieu.
