This is a most excellent idea.

Maybe with pics/drawings of the said items in question?

Televue RFL-4087 focal reducer system threads is a M65 diameter (2.55") x 24 TPI (UNC).

Most finder illuminators are M8 x .75mm pitch thread.

Skywatcher reticule eyepiece illuminator is M8 x 1mm pitch thread.

Thumbscrews many many types here.


edited TV threads dimensions.
