OAG question
I have a question about Off axis guiding (OAG).
I currently have a scope and a guide scope so i know about the Pros and cons with this type of setup.
My new scope will have a FL of 3000mm, and people recommended I go down the path of OAG. I've been doing some reading and it seems like this could be the way to go. I find a OAG with a large prism around 12mm and get a ZWO camera with a sensor around 11mm, like the ZWO 174. This should give me a wider FOV and smaller magnification to find a guide star compared to a typical guide camera. Would this idea work in theroy? Or get a larger guide scope with a FL of 1000mm, this what be a ratio of 1/3. What are the pros and cons with a OAG setup from your personal experience?
