I had some issues with the sensor on the dome rotator - it became erratic in operation. I had to take the whole control box off and clean, re-seat and tighten the sensor and the gear that rotates the track.
I got my gear in this week and last night finally got it all together and operational. It was great having the dome follow the scope around and keep itself in the right spot as the scope adjusted position.
Although I've yet to get a pier in place I've already noticed the difference with having the dome. It was very cold last night, but within the dome, being sheltered, I was a lot more comfortable. Of course, the shelter made a massive difference to the guiding as well as it didn't have to compete against the wind.
It's also cut out a lot of the surrounding light from the houses and streetlights around. I'm not sure how much that will help, but it can't hurt.
Finally, tonight is looking good and it's going to be great to walk outside, flick on a few switches, load up the software and go for a long imaging session.
