Hello, im up in the air with a choice of three telescopes in my price point around $500. Maybe you can give your opinion on which is the biggest bang for my buck considering durability, capabilities, portability, and the quality of images from the moon to deep space.
First is the celestron nexstar 4 se(aperature 102mm focal,length 1325,focal ratio 12.99)
Second is orion skyquest xt8i intelescope (aperature 203mm, focal length 1200, focal ratio ?)
Third is mead ext-90 at (aperature 90mm, focal length 1250, focal ratio 13.8).
Thanks for your time hope to hear back!
