Hi Matt. There are a number of FR you could use, but for a relatively inexpensive 1.25" one I'm quite partial to my Mogg one (I've tried a few
). If you check out the Webcaddy site you will find a bit of a description of it and how to increase the reduction ratio. Works well with an SCT but is not so friendly with refractors and Newts when trying to extend the reduction ratio (not enough in focus travel )
