I worry about the difficulty of collimating these; I guess it will be similar to the GSO RC. Mirrors and focuser have to be squared up on the same optical axis and the distance between the mirrors has to be correct.

Have people found a reliable method for collimating the RC's?


On another note, GSO no longer provides dielectric coatings on their RC mirrors according to Astronomics. I had visions of putting the garden hose up the tube to wash the mirrors but I guess not
