Check the Alpine astro website for list of all the rings required for various eyeieces. You don't don't want to use it for high powere observation as it induces Spherical Aberration on -axis, which is not going to effect prime focus photography

Hi Mark

As stated i know its all setup right, with correct spacing etc. i know its fine, and just me being an idiot. but it does appear to shift focus. I have the rings, and i ahve them spaced correctly, i know this as i can get an image, if i move the MPCC assembly out of the focuser its a very nice image to!
