"Here is a question for anyone who has an R2, as well as a R1 camera. Have you tried the R1 remote with the R2 camera. I find it perplexing, that the down button on the R2 supplied remote, does not function. The down button works on the camera, so what gives? I've seen this, or a similar UTC controller on a Youtube video, where he uses it to navigate settings in a security camera, and both up and down buttons work. Any info appreciated.
Just purchased a new R2 at RTMC this past weekend, and immediately, out of the box, noticed that the down button did not work. I called Mike at Orange County Telescope and he told me that that is the way it is, now, and I'll quickly get used to moving up through the menus to get to the desired location, even if it is the next line down. I suppose that I can live with that! Camera was easy to set up on my AT72EDII using a star diagonal -- could not get to focus in straight line position, so I'm going to have to add an extender, which I've ordered. Beautiful sharp view of the beach several miles away (daytime), but it's been cloudy all week, so no night imaging yet.
