Hoping for a little more advice. A little lopsided tilt. Here are two images of the same object , one with the camera on the West side of the mount almost upside down, and the inverted view after a flip from the camera on the East side of the mount. Shows tilt on different sides of the image.
I think perhaps this is focuser movement in my FS102.
Any other suggestions? Joshua has fixed my other tilt problems ,making a better 72 mm OAG to Tak tube adapter ( plenty of stars and guider camera focus travel now ) and every thing else is threaded together with zwo adapters.
Hi Ray.
If the only thing that changed was a meridian flip, you're probably right, either tube flexure (colimation) or image train flexure. Try taking an image at the zenith and an image at 45 degrees altitude and compare them...
