I have to say.... these look very tempting. The wife says I can't spend anymore money for now.
I have been sort of doing a manual version of this lately. In my back yard when I set up, I know pretty much where south is... but not having a permanent pier I am always off a little when I put the scope out to observe. But being close, I have been doing a 5 minute exposure before I turn on the mount, and looking at the the image to see where the stars have revolved... and having done this a few times now, I sort of know how much to adjust the scope by to line the pole up to the centre of the image. It's been working pretty well. The image shows what I see when I do these test exposures. So you can see where the pole it, and I roughly, from practice, know how far I need to adjust to bring the to the middle. Yeah, sure I still need to do some refinement... but it's pretty close.
But this camera says it takes 2 minutes.... 30 arcsecond accuracy... I am going to have to find the cash I think. I'm sure I don't need two kidneys....
