Hi folks,
I am a newbie here but I have been hanging around for a little while. I can only say it's a great site with lots of good natured people on it with good advice.
I am hoping someone can help with a problem I am having with a second hand TV85 scope I recently bought.
I find that the focuser tube slides out of focus at sharp angles when viewing towards the zenith.
There is a small screw type clamp on the tube that can fix the tube in place, but this is difficult to use when you want to refocus, particularly at higher powers. I find that a small bump/adjustment sends vibrations through the scope for a few seconds afterwards.
I dont have enough technical knowledge to modify/service the scope at this point in time. I would really appreciate some feedback on a solution.
Nick
