Good morning,

 

I have A question for those using A Newtonian for astrophotography. How do you typically index your focuser when your mount is in the home position? I have been setting it vertically upward, having it to either side seems to effect balance. It works pretty well, though I need A small stool sometimes to see the camera display. Do any of you set the camera vertically down? 
 

thanks!

Rick

I think I've seen the camera/focuser in the vertical down position more than any other way.   Why fight gravity ?  :)

I use vertical-down to help keep the loads symmetrical and reduce the moment arms of the loads. This also allows me to mount a guide scope along the top centerline of the telescope.

Food for thought.

Likewise, I mount my camera with the focuser ‘down’.
Since I’m using Backyard Nikon to control my camera, which is ‘tethered’ to my laptop, I can see the camera view on the computer screen.
The only time I look at the image on the camera’s LCD screen, or look through the viewfinder, is when I do my initial sky alignment, to be sure I’m on the correct star(s) and to check that the camera is roughly focused.
