Yes, first tighten these two screws and see if that corrects the issue. There are also 4 tiny set screws, one in each corner. They are used to set the distance of the pinion from the rack. The third s

Possibly, but not this year. Rolando

Autofocus can shift the camera which will cause the star to jump. Try turning off Autofocus and see if you still get the jump. Rolando

Mounts will be instructed to move by two different methods. One is by coordinate moves, the other is by timed move where a 1 second move command corresponds to a 15 arc sec move. Coordinate moves are

Hello Astronuts, While visiting Hawaii in the spring of last year I had a few clear nights and did a galaxy tour in Leo. Here are some of the images. All were short exposures, snapshots if you will, a

Biggest standard refractor was a 10" Triplet. Biggest refracting system we made was the 12" Honders which used 2 refracting lenses of 12" aperture along with a folding mirror and a 3rd element of 4" a

For imaging at ~F5 or for visual at ~F8? Rolando

Great, very nice! You got a nice eclipsed Moon there. Rolando
