Cheapest option is to move the mirror up, you can try doing this by allowing it to rise on the collimation screws to the limit of the travel, if that's not enough you could get longer bolts and springs but I would discourage cutting the tube to shorten it.

I'd try cranking out the mirror first and see if that gets you to focus, but it will push the visual eye piece focus further out to the point where you may need an extension to reach EP focus.

You need to work out how much more travel range you think you will need to reach focus with the camera, that informs your next step.





Good luck
