Customer Reviews (5.0 / 5 · 5 reviews)

Jason ★★★★★

The temperature compensation is spot-on—it held focus perfectly through a 15° drop last night. ASCOM compliance made integration with my existing imaging setup completely seamless.

Robert ★★★★★

Setup was surprisingly painless, and once it was wired into my ASCOM rig, the response is instant and dead quiet. I've been slewing and fine-focusing all night without a single hiccup, which is more than I can say for my old manual setup.

Grace D. ★★★★★

The fine adjustment knob on this unit gives me precise control over focus that I never had with manual rack-and-pinion systems. It connected to my ASCOM setup without any hiccups, and the responsiveness during imaging sessions is a game-changer.
