One of the problems with focusing a telescope at high magnification is that even the slightest touch on the most sturdy mount will still shake the scope a little bit- making the image blurry for a few seconds every time.
In this hack we will be making a little cap to fit over the focuser knob on my 8″ Celectron SCT.
Parts needed:
7/8″ inch rubber cap- probably designed for the end of a table leg or ??
A piece of stiff wire- a coat hanger will do nicely.
Years ago a salesman at Scope City in San Diego showed me this little trick- and even gave me a few extra caps. I still have 3 of them.
Bend your wire into an apropriate handle shape and length as desired.
Stick it into the cap thusly.
This reduces the vibration transferred to the scope by a -lot-.
