New Focuser
I received my new Crayford style 10:1 Focuser yesterday.
It works perfectly well when it's horizontal but it can't hold the weight of the draw tube when it's vertical. The screws will hold it in place so it doesn't move,but you can't adjust focus, otherwise the tube just falls straight out to full extension. Are there other adjustments that I need to make?
It's frustrating the hell out of me. Am I not using it properly or have I bought myself a lemon?
PS. My astro goodies arrived and I had pristine skies, so I knew something had to go wrong.
