Let’s move the primary mirror inside of an Orion XT8 or similar telescope (to focus a DSLR)

As you know you can’t reach focus with a dslr on the original Orion ST8 Dobsonian. Like many reflector telescopes the problem is that the focuser runs out of travel. In a previous video I demonstrated ways to get around this problem. I mentioned moving the primary mirror forward as one of those ways. I show how I performed this on the XT8 and the required hardware. Many other model reflector telescopes will be very similar. Even if you don’t have an XT8 you should be able to see what’s needed for your particular model. I hope to illustrate the idea across those various models. This process is fully reversible should you wish to return it back to its stock position. Upon modification you will be able to focus with your dslr prime through the telescope. Eyepieces will also still work but require extension tubes. Why go to the trouble? The increased field of view offered by larger dslr sensors has advantages. Clear skies.
