Customer Reviews (4.6 / 5 · 5 reviews)

Alexander ★★★★★

Finally dialed in my backyard astrophotography rig with this. The single board setup made wiring much cleaner, and the HSM30 motor engages smoothly even with my heavy camera hanging off the focuser.

Olivia ★★★★★

Installing this on my 2.5" Feather Touch was straightforward, and the single control board is compact enough to mount cleanly. The response from the hand controller is immediate, which makes fine-tuning focus much less frustrating during imaging sessions.

Sofia ★★★★★

Took me a bit to figure out the wiring, but once it was connected to my Feather Touch focuser, the control board responded instantly and feels rock-solid. The single board setup keeps everything neat on the scope, and the fit on the 2.5" rack was spot-on.
