The AstrOasis Tilt Adjuster is one of those rare accessories that solves multiple real problems at once: sensor tilt, cross-brand camera/filter wheel mating, and that last annoying millimeter of backfocus tuning. You can adjust tilt without detaching your camera from the rest of the imaging train, fine-tune backfocus from 5.0–5.5mm in 0.1mm steps, and seal up light leaks so your flats and darks don’t get sabotaged by stray glow. It’s not just a tilt plate—it’s a universal bridge between ecosystems.
Easy tilt adjustment without teardown
Adjust tilt without removing the camera from the filter wheel or imaging train
Supports 3-point or 4-point adjustment
4-point method can target sensor edges or sensor corners for more precise correction
Broad multi-brand compatibility
Designed to connect cameras and filter wheels across popular brands in a consistent way
Makes gear more reusable when you mix-and-match ecosystems
Backfocus fine-tuning built in
Adjustable occupied backfocus from 5.0 to 5.5mm
0.1mm resolution so you can actually land the spacing you need
Designed to match (or closely match) typical camera tilt-plate spacing, so it usually doesn’t add backfocus (or increases it only slightly, ~1mm)
