Description
In order for the Bahtinov masks to work properly a certain focal length needs to be exeeded. The minimum focal length stands in the modelname (min750mmFL), you can still use the mask with a lower focal length, but I wouldn´t go to far below. However going higher is not a problem.
The maximum aperture (max210mmAP) refers to the actual lens/ mirror size not the outer diameter of the telescope. I think I left enough space so the mask still fits over the outer diameter.
The screws come in two sizes, if you scope is quite a bit smaller to the max aperture I would use the longer ones. Also don´t thighten them so much that it bends the mask just enough so it doesn´t fall off (centering the mask is not needed as long as it´s not completely off).
Tip: If the mask is to big for your printer you can cut it in four halfs (PrusaSlicer has such a funktion), then glue them together it´s what I did with my mask.
Note: I got the patterns for the Masks from a Bahtinov Mask generater webside:
Also if there is a certain size that doesn´t fit with the existing masks or a mask that doesin´t fit at all, just hit me up I can add them to the existing ones.
