A few questions:
What do you use to 'smootherize' the focuser's up and down movement again? Mine is starting to squeek when focusing.
Gear oil? something else? Something economic? Or something expensive?
I want to replace my 6x30 finder for a red dot finder,
The 6x30 is mounted with 2 holes and their screws,
the red dot description says it will come with a dovetail mount (what is a dovetail mount?)
and that is uses 4 screws.
Do i want to drill extra holes in the telescopetube? or how do i want to attach it? (i do not want to keep the 6x30 finder mounted also)
Does anyone know a source for (large) aluminum focusknobs? preferably the 'APO style' ones, but anything is okay,
i want to replace my plastic focusknobs.
My plastic knobs have a round fitting that is flattened on one side, i'm not sure how this is called.
And finally: Where to get (or of what to make, and how to attach) a primary mirror centerdot, how big a dot do i want for a 6" F/5?
And also What kind of a collimation eyepiece do i want? A Cheshire? A laser? Something else? I prefer economical, and how do they work and what is nice (doesn't have to be nicEST) to use?
