Customer Reviews (4.8 / 5 · 5 reviews)

Samuel ★★★★★

Installed this on my Hedrick focuser over the weekend, and the automated focusing is a massive time-saver during imaging sessions. The temperature monitoring gave me real-time feedback that kept my rig stable all night.

Aurora ★★★★★

Setting up the auto-focus routine with the Hedrick focuser was surprisingly painless, and the delta-T readings give me real confidence when shooting through the night. It's cut my setup time in half.

Riley ★★★★★

The temperature monitoring feature really helps me dial in my focus across a cold night without second-guessing. Paired with the fan control, my subs are noticeably sharper now.
