Not sure if I should post this topic here, or in the refractor or SCT forums?
Anyone use an apo refractor on a Nexstar 6/8 SE mount?
I'm asking because I now have a spare Nexstar 6/8 SE mount and was wondering what type of APO refractor I could mount on it?
Is it basically the length of the refractor that I should be looking out for? I also have an ADM dovetail bar that has been fitted with extra holes to extend the bar even higher. It's basically a bar for an 11" SCT but with extra holes. Although the Edge 8 I had previously tilted when risen too high, perhaps an APO with less weight can be extended.
Would you get an 80mm or 100mm APO? Or a bit more? This is for solar viewing with a quark and for deep sky night views.
