As I said Im still building this rig but as far as visual goes its fine. For guiding I guess Ill find out when weather and time permits. Ill use it to sort my 9.25 setup and hone my AP skills. Train of thought leans towards OAG, prob better people here than me to answer suitability, I saw somewhere some complaints of odd shape stars guiding with the 50mm Orion on bigger SCTs. Apart from the maths trial and error I guess....
Just found this in my bookmarks hope it helps...
