ASI6200 with M68 OAG and M68 tip/tilt plate

mrpugh55

Hello

I have followed the instructions to assemble the camera, M68 OAG/tip-tilt plate, and that includes removing the tip/tilt plate on the front of the camera. I have tried 2 guiders (Lodestar x2, STi) and none of them come to focus in the OAG.

The easiest solution for me will be to remove the helical focuser and replace it with a 1.25" barrel adapter. What is the thread size of the top of the M68 OAG? i.e where the helical focusser threads into.

Otherwise, what other solutions are there? There are no adapters I can see that I can put between the FW and the OAG to extend the distance so to bring the guiders to focus.

Also, what are the screw sizes that attach the M68 OAG to the filter wheel? Why do you not provide additional screws with the OAG when you sell it?

Hi Martin,

You can refer to the title"Features" on this website: https://astronomy-imaging-camera.com/product/m68-oag-off-axis-guider

And there is an attachment for your reference.

I have teh ASI290mm camera and the full ZWO setup (OAG, ASI6200, new filter wheel) and I have noticed that the OAG camera BARELY comes into focus with the OAG helical focuser racked all the way in (using the shortest adapter that comes with the camera). You might simply not have enough back focus left and need to move the prism UP a little back into the body of the OAG.
