I've perfectly adjusted the tilt on my astrophotography setup, which consists of an Esprit 120 telescope, a Riccardi 0.75x reducer, and an ASI 2600MM Pro camera with a 2" filter wheel.
However, I've noticed an issue when rotating the camera within the focuser -whether manually or using the Deep Sky Dad motorized rotator. Depending on the rotation angle, the tilt measurement changes noticeably. Although the tilt remains within acceptable limits for this setup, the issue becomes visible through distorted star shapes, particularly in the right corner.
Importantly, I verified that tilt measurements at a specific camera angle remain nearly consistent across different areas of the sky. Therefore, the variation in tilt seems directly linked to the rotation angle?
My setup: telescope, tilter, reducer, rotator, filter wheel, camera.
Could someone please help me understand the source of these tilt variations, especially considering the use of a mechanical rotator? Any insights or explanations would be greatly appreciated
