I have been unable to get a clear answer on whether a IR/UV filter is helpful in imaging the planets. Celestron website seems to imply a filter is required....

Do most people use the output size of 320 x 240 when imaging with the NexImage? Is there any time when 640 x 480 would be acceptable? Thanks...
