Rotating Newt OTA within Tube Rings

Recommended Posts

gfletcher

Hi Guys

What are the tricks to make rotating the newtonian  OTA within the tube rings during an observing session an easy operation?

I seem to have so much difficulty rotating the OTA even with the tube clamps loosened.

Is there any method to make this a less frictionless manouvere?

Thanks Guys

I use on my 200pds a sepearate scope ring , so main ota rings loosened to turn, top ring locked for balance same as Astro baby guide

I used a 25mm wide strip of 3mm thick PTFE held on to the tube withs a huge jubilee clip.

There are some interesting solutions here. My TS Optics (GSO) 150mm, f/6 Newtonian is particularly difficult for me as I have a disability. GSO Newtonians are supposedly renown for being difficult to rotate.

I almost always knock the finder out of collimation as I'm trying to rotate the OTA.

So much so that I invested in a 25mm Altair cross hair eyepiece to make on the spot adjustments after rotation lol.

My 130M was much easier to rotate!
