So i have a eq8r on order. I initially was planning to defork my Meade lx90 12 inch… however after a few tweaks my lx90 (on a wedge) seems to be guiding well again.. but I noticed that the stars are a little bloated and the images are not as ‘crisp’ as I would like. The question I have; would a GSO RC 12 or 14 perform better? What about a 14inch f/8 ACF?.. will a 6 inch refractor be able to grasp enough light for small galaxies? Lastly, what about dobsonians?
