Tripod adapter flanges

The parts you mention should work fine to connect the UFC between the diagonal body and the 2" barrel. However, due to the threads, the end position of the UFC cannot be adjusted to your preferation, it might stop at an unfavourable position. We are thinking about developing an Camera-sided UFC adapter with S58 dovetail receptor. This would allow exact positioning to your needs. However it will take months before this product may come to the market.

The optical lightway can be found under the Tab "Specifications". It is adjustable from 32 - 38 mm.

You probably need to adjust the two brass pins on which the mirror rests in its lower position. This way, you can move the image along the optical axis of the telescope (either closer to the telescope or to the camera).

To test this, take a look through the eyepiece and move the mirror slightly up - if the star moves in the desired direction (or contrary to it), then you need to adjust the brass pins. Please see page 11 in the manual (chapter 3 - Adjusting the mirror). If it moves sideways instead, things get complicated. But that's most probably the solution.

Due to the thickness of the glass, we neeed to add 1/3 of the filterthickness to the backfocus required, which makes it aprox. 63,7 mm. You should keep this in mind when making the calculations later on.

Since the Field Flattener has a M48 Male thread, you would need the #2459129 Telescope Side Adapter

Next you would need a few spacers which can be calculated by subtracting from the required backfocus, the optical length of the other needed adapters. A list with the calculations and the needed articles is included below. We determined that you would need one 5 mm spacer #2459141

as well as a VariLock spacer set at 18,4 mm #2459145

Then you would need the UFC Basis #2459110 which has an optical length of 13 mm,

the 2" Filter Slider #2459112 (we suggest one slider for each filter, which makes changing filters faster and more comfortable),
