I'm going to be SO real about this… I have an Avalon Instruments mount, it is one of the most beautifully crafted things I've ever owned in my life - and I imagine the UPAS is exactly the same as far as build quality…
If your telescope is in a hard to get to location (roof mounted observatory) or at a remote site where you might only need to adjust PA 2 or 3 times a year, but you're a few hundred miles from the observatory, then sure, this would be worth it…
if you're moving your scope in and out from the house every time you use it, I honestly think I could get my polar alignment sorted from raw setup of the mount, to within 30 arcsec (which is MORE than good enough for nearly any rig) in maybe 3 or 4 minutes.
I guarantee you, you have something more important you could spend the money on that would provide tangible benefits to your astrophotography, where as this unit will litterally only save you a couple of minutes. You'll never get noticably better images as a result, you'll never have better data as a result, or neater cable management as a result…
