Right. So, you just move the tripod left or right to align from location and adjust the legs a touch for "up" and "down". Can confirm I am going to try a green laser to align it.

So, I can try and use the existing head I have to move the DSLR.

Should I go curved rod, or straight rod? Curved looks correct right now and let me stay aligned longer, right?
I think I will make the attempt to motorize it.
1rpm, 3rpm or something else? Why this speed?
I need to decide on the motor (9v/even 6v compatible sounds good for portability?)
Will a lm317 kit be needed to regulate the speed? Will that work with 6v?

Perhaps this motor would be suitable? https://www.ebay.com.au/itm/DC-6V-1r...AAAOSwH05ZsLCx

Also, this will probably become helpful: https://blarg.co.uk/astronomy/barn-d...ker-calculator (thanks Aaron)
