First of all thanks to Frostyfriday for posting this little tool.

I truly like the simple original design by Frostyfriday.

But at the same time I realized that the screen/reticle on which the Sun gets projected, is too thin and fragile. If for some reason/accident, it breaks, then the whole thing has to be reprinted.

Also, there is no way to collimate it once it gets mounted on the telescope.

I tried to remove these shortcomings by redesigning it so that the new reticle can be installed any time if the old one breaks. The reticle is attched using the M3 screws of 8mm length. The Sun-finder body has the space to insert the M3 nuts in it (one on each side).

Last, I added the face of the Sun and the text to give it a cool looks.

The centre M3 screw (approx. 20mm length) on the Sun-finder body helps in verticle collimation while mounted within the finderscope mount. Rotating the screw clockwise or anticlockwise raises and lowers the reticle side of the Sun finder and helps in centering the image. You need to insert the M3 nut in the space at the lower-back side of the Sun-finder.

I am also posting the finderscope mount (best for 80mm diameter telescope) that can help in horizontal collimation of the Sun finder with the help of side screws on it. There is about 1.5 mm of clearance (on each side) once the Sun finder is mounted in the finderscope mount making the collimation very easy.

Adjust the 2 screws on the front of the finderscope mount to horizontally collimate the Sun-finder, and use the rear 2 screws of the mount to center the Sun-finder, once the Sun-finder is vertically collimated using it's own screw.
