Z’Tilter Back Focus and Tilt Adjuster for ZWO ASI2600 and ASI6200 Series
Our Z’Tilter uses a specially modeled front flange and load-spreading geometry to minimize elastic deformation as the imaging train changes orientation and across temperature variations. The result is a tilt adjustment that stays put once dialed in, instead of requiring constant re-tuning.
Developed by OGMA in the USA, the Z’Tilter is designed by astrophotographers for astrophotographers who prioritize mechanical stiffness and repeatability once tilt is corrected.
A single unit can be configured for either 3-point or 4-point tilt adjustment, depending on user preference.
Highlights
- Preserves native back focus
Maintains the original 17.5 mm back-focus distance of ZWO ASI2600 and ASI6200 cameras. - Rear-accessible tilt adjustment
Adjustment screws are accessed from the rear of the camera, allowing tilt correction without disturbing front-mounted accessories. - Configurable adjustment geometry
Can be set up for 3-point or 4-point pull-push tilt adjustment — you choose what works best for your setup. - Camera compatibility
Compatible only with ZWO cameras from the ASI2600 series (duo and non-duo) and ASI6200.
Not compatible with other camera brands or models.
Customer Feedback
A picture is worth a thousand words

I had made hundreds of attempts to eliminate the tilt with [a premium tilt solution from another brand] to no avail. See the enclosed image for the results with the Z'Tilter in just five adjustments.

Camera Compatibility
With help from the community, we have confirmed the fit on the following camera models:
ASI2600 → No shims needed
ASI2600 Duo → Shims required and included
ASI2600 AsiAir→ Shims required and included (same shims as the Duo)
ASI6200 (pre-2025) → No shims needed
Other models that share the same body diameter may work with this product.
If you find a 2600 or 6200 camera that doesn't fit the Z'Tilter, please let us know. We will either make the correct shims for you or refund your money.
Thank you for helping us support other owners of this product!

Z'Tilter Installation
For Black and Star Spanged Editions
Update: Expanded Compatibility for Z’Tilter
When we first recorded the installation video for the Z’Tilter, it had only been tested with the ZWO ASI2600 series cameras. Since then, the community has successfully tested and used the Z’Tilter with other models, including the ASI2600 Duo and ASI6200.
For the ASI2600 Duo cameras, we now include six CNC-machined stainless steel shims with every new Z’Tilter. These shims compensate for a slight mechanical difference in the ASI2600 Duo body and should be installed beneath the tilt ring, where the six screws secure the ring to the camera. This ensures a perfect fit for the ASI2600 Duo camera series.
We’re grateful to the community for helping expand compatibility and validating performance across more setups!
