I am looking for a mount that can be programmed to go to alt-azimuth positions.
That is NOT the same as a "go-to" mount, which typically means RA, Dec positions to find an astronomical object.
This is for making a terrestrial mosaic (panorama) which includes the sky.
I have Gigapan and Roundshot commercial mounts, but I want to use this for heavier lenses than they take. Plus they are internally programmable but you can't externally tell them what to do.
I also have one I made myself, along with software to control it. But I need an additional and heavier duty version so I was hoping to buy something that would work, or that I could modify.
Instead of an alt/az interface, I could also interface directly to stepper motors for alt, az.
The iOptron iPano AllView Pro https://www.ioptron....duct-p/3600.htm mount almost is what I want. It looks very similar to Gigapan, with almost identical interface. It can be remotely programmed in a sense but only with their app, which is more of a remote wireless interface to the same commands available on the display. I could reverse engineer what the protocol is, but that seems like a waste if there is something better.
I I have built a mount like this already have all of the software to control it. I just need to get an additional, heavier duty mount so I am hoping there is a product I can buy.
Several mounts have an alt-azimuth mode. That includes Rainbow RST-135, Hobym and Avalon Instruments. I have been unable to download the RST-135 manual. The Hobym manual does not say - apparently you can go RA-Dec go-to in alt-az mode, and you can use the hand controller to do up down, left, right.
However it is hard to find information from them on how they are programmed in alt-az mode. Of course most astronomical users want to use RA, Dec coordinates for convenience, but that is not what I am after here.
The same is true for mounts like iOptron AZ Mount Pro, and similar from Sky-Watcher. They have an alt-az mount with steppers, but it is unclear to me how to interface with it.
One possibility would be a manual alt-az mount that was easy to motorize.
