We do not sell ZWO cameras, but as far as I can see, the camera comes with a T-2-thread and a 1.25" nosepiece.

If ZWO's nosepiece has got a filter thread, you can insert the filter there; otherwise you can use our
Baader 2" / T-2 Nose Piece (T-2 part #16) # 2408150 to use the camera with 2" filters
or
Baader 1¼" / T-2 Nose Piece (T-2 part #14) # 2458105 to use the camera with 1.25" filters.

The 1.3x configuration works with every 1.25'" eyepiece which has got a standard filter thread and an empty barrel - it is inserted ca. 15 mm deep into the eyepiece, this much space must be available.

There are eyepieces which already have a built-in kind of barlow element inside of the 1.25" barrel, here you can't insert the Q-Barlow.

The distance between your camera's T-ring and your focuser with inserterd Barlow is ca. 14mm, the nosepiece is ca. 2 cm long.

You already have the solution (almost): Like on most of our 2" star diagnals, you can remove the 2" nosepiece and then have a 2" SC thread, so you can screw the prism directly onto the SC-thread of your telescope.

Of course, it will usually end up in an uncomfortable position - but we offer the NexStar Locking Ring 2458270 which works as counter nut.

To attach the prism housing to your telescope, you may have to unscrew the eyepiece clamp, because otherwise it may hit the focus knob when you screw the prism onto the telescope.

The Astro Amici Prism # 2456120 is suited for high magnification, while the 2" Amici # 2956152 is not.

Standard Amici-prisms (like spotting scopes, too) are good for magnifications of up to ca. 60x-100x; of course this depends on the quality which you expect. This is the range of magnification suitable for terrestrial observations, where air turbulences usually prevent higher magnifications. Especially stars or bright planets in the center of the image show imperfections clearly.

The Astro-Amicis allow for much higher magnifcations - the magnifications which can be used astronomy.

This is not a problem of the telescope which you use, but of the optical design of the prism. There is an edge going through the middle of the prism which can cause reflections, and also both sides of the image need to be at the perfect angle. There is of course no strict limit for the magnification, but somewehere between 60x and 80x is a good limit for standard prisms.
