M42 helicoids?

#1 Post by Piter_ » Tue Feb 04, 2020 11:13 pm

Hi everybody.
Does anybody have experience with M42 helicoids for mounting a camera on a microscope.
Something similar to this:

My primary concern is if they drift under the weight of a camera.
Thanks.
Petro.

I've used one on almost every camera adapter I've made. They will wobble a bit if you are handling the camera but they won't drift.

ditto to that. they are available in quite a few different lengths, with an increasing span along with increasing base length. if you can refine your system down to the minimum length necessary, it will reduce the potential for wobble, somewhat. they are good, especially given their low cost.
