I have an aging friend who would like to buy a telescope for his rural property, he doesn't know a lot about the equipment choices and asked me. His requirements are pretty basic: visual use only, he would like to be able to see DSOs (brighter galaxies at least, nebula, and the odd comet), has to be able to be used sitting down (bad knee and back), and it can be either Alt/AZ or EQ mount but Goto is ideal. His budget is around $5000 total. As I have been imaging for the last couple of years I am not up to speed on visual scope developments so I am asking here for input. I am assuming based on his requirements, that it's probably going to be a refractor. Opinions?
