If so, the instead of using the extension tube, use a Field Flattener in its place. It will have the same 2 inch noise-piece interface for the scope and same t-thread interface towards the camera.The Stellarvue Field Flattener/Rotator for SVX102T is a rotating field flattener for the Stellarvue SVX102T and the SVX102T-R.

When WO 3 (an n-type semiconductor) is coupled with Cu 2 O (a p-type semiconductor) to form p-n heterojunction, the built-in electric field exists in the contact area of p-n junction due to the different Fermi energy between WO 3 and Cu 2 O New, dedicated flattener by William Optics optimized for use with their Z61 Apo telescopes ♦ Suitable for all refractors, requirement is a focuser from 2 ...

The EQ-1 is pretty undersized. For an ultra-portable equatorial-mounted option it might be just about adequate, but these small EQ-1 mounts are really not very good. They tend to be wobbly; they don’t stay where you leave them, and their tripods are somewhat shaky too. Details about Orion Field Flattener for Short Refractors.
