Crosshair focus mask for Explore Scientific AR102 102mm f9.8 achromatic refractor telescope. Slips into dew shield for more accurate focus when setting up for astrophotography. I went with this design as it uses less material than a Bahnitov mask and also far less time to print. Fits comfortably in my AR102 f9.8 telescope. Does NOT fit Svbony SV48P 102mm f6.5 achromatic telescope. Its diameter is slightly too thick to put in the dew shield of the Svbony telescope. I plan to make one that does fit it in the near future. I will post it when done. Of course, if you like, you can download the scad file for OpenSCAD and make any changes you like.
