Hello all,
I have my own garden observatory and I have a setup with a Newton telescope Vixen R200SS.
The usual parking position I know is to point the telescope at Polaris. But this doesn't work for a roll-on-roll-off observatory.
I am wondering which is the best parking position:
a) telescope pointed at zenith, with the advantage that the mirror is horizontal. The disadvantage is a torque moment on the eyepiece focuser due to the relatively large QHY 600 camera.
b) Telescope pointed at the northern horizon and the eyepiece focuser with the camera pointing vertically downwards. The advantage is that there is no torque on the eyepiece focuser. The disadvantage is a vertically oriented mirror that may be subject to movement and misalignment.
What do you think is the best position?
