IRF90 Integrated Rotating Focuser (600180)

The 30mm travel range is a game changer for my automated imaging sessions, handling my heavy OTA with absolutely no flex. It locks in focus perfectly across the entire journey, and the rotator moves smoothly without any shift. My flats have never been more consistent.

Setting up this focuser was straightforward, and I’m impressed it can handle my heavy 40‑lb imaging rig without slipping. The 30mm travel range gives me precise focus control for every filter change.

The rotator's 90mm aperture cleared up my framing issues instantly, and the 30mm focuser travel gives me fine control even with a heavy CCD camera rig. No more fighting with sloppy adapters or worrying about tilt.
