Howdy
Am looking for recommendation for a replacement focuser for the Skywatcher 200mm F5 Newt, the focuser on there is ok visually, but even if i get perfect collimation, i am sure the grub screws on the 2" collar and skewing the CCD slightly, so i need something with a very snug, precise fit, and with preferably a 10:1 fine focuser, the crayford already on the SW sits a couple of inches higher, so i would need something with loads of travel, a 2" extension, or some method of getting it to focus
thanks in advance
