Advice on fitting a rotator

[teoria_del_big_bang]

I currently have a pretty robust setup that I am 95% happy with, and the main downside I am not happy with is that I cannot easily rotate the camera to change the FOV angle.

In theory on my Esprit Pro I can loosen the locking ring and adjust the angle but really I do not count this as a practical option.

Ideally if money was no object and I could fit one in without affecting the optical train I would love one with a motor that I can operate remotely but I do not think this is necessary as it is just something I need to do once in the night at start of a session so no big deal to do this manually.

• Is there a preferred rotator for this sort of setup that is particularly better than the rest ?
• Where ideally is it placed in the optical train ?
  • Ideally for me would be between the FW and camera but then it is not ideal to have this distance any further than necessary.
  • If placed before the FW then I have a fairly big FW rotating as well which may mean it can hit the mount legs if in certain positions.
• Can they introduce other issues such as tilt ?

I use an optec Pyxis LE rotator its 2"  nose piece forces me to put it directly into the focuser which is ideal fir my setup.  I would always go for having it before any reducer, filters etc so they move as a set reducing any shift between them.

I have not  noticed any tilt issues but my application is not sensitive to tilt.
