Hello All,
I'm using an older Konus 200 reflector that I recently bought used. It seems to be of the older variety with large focuser and very narrow spider vanes. As one might expect, it's in need of collimation. I was able to give it a "rough" collimation by adjusting the phillps head screws on the rear of the mirror cell. Hoever, to lock it in the new position requires turning the set screws that are adjacent to the adjustment screws. It's not evident to me how to turn these - The screw looks like it may be an allen hex head type, but the hole is smaller than the smallest allen wrench I have, which is 1.5mm. Does anyone know how these set screws are used?
Thanks,
Tom
