"What are the pros and cons of low/ high profile focusers. The 2\" R+P fullerscopes focuser, that is part of the 12\" newt I'm rebuilding, stands 5\" tall and I'm considering reusing it as it's built like a tank with very little perceptable backlash and slop. The only real negative is it doesn't have compression rings. I can't, on the face of it, see why a low profile focuser would be better other than maybe better back focus for imaging (I'm visual only).  Would I be right in thinking that the lower the profile of the focuser, the further from the end of the OTA it has to be to prevent stay light entering? \n"
