Although I no longer have my 8 inch scope, this forum is more active than the Nextar GPS forum so here goes. I own a Cellestron 11 inch SCT on an alt/az mount. Once I get a good alignment, it slews to any object that I choose with either the handset or Nexremote. However, when I connect to SkySafari for my Ipad, Astroplanner, Skytools3, Stellarium of Cartes du Ciel, it NEVER slews to the exact same place as Nexremote or my handset. I thought that my scope was out of balance but it is balanced. I test it with Polaris. I get a good alignment and slew to Polaris and have Polaris centered. I then connect to any of the above mentioned programs and even while on Polaris, I slew to Polaris again and Polaris is usually within the FOV but it is never centered. It will be quite a bit off. I have tried this with each of the programs and its the same thing. What could be wrong. Some of the programs ask whether to use J2000 or Jnow. I always choose Jnow. I use the GPS of my scope to put in my home coordinates in each of the programs. I am baffled.
