Rotator for ASI294

[AndyThilo]

Hi, the rotator on my Esprit 80 is far too difficult to access and use so I'd like to add a rotator between the field flattener and camera. Currently it's setup as below:

As the 16.5 spacer is M42 camera side and M48 flattener side, I thought it would be easier to swap out the 21mm spacer which is M42 both sides. Any thoughts on a decent quality manual rotator? I don't want any tilt issues. 

Cheers

Thinking of these 2 to cover the 21mm

The baader is 15mm optical length, and spacer 6mm

Really? Both of them?

[AndyThilo]

Well I don't want to move the focuser around just for image composition and with my Pocket powerbox and USB hub, access to the other is virtually impossible.

So yes, both of them.

Ok but the problem that you need to be aware of is that the smaller the diameter of the rotator the harder it is to build it so as to prevent tilt.

Yeah I understand that, I wasn’t expecting one for peanuts, and spending little on an important component is stupid. I’ve ordered the Baader and and going to get a angle sticker made for it (or some marking anyway.
