I have a Celestron 6SE and saw mars for the first time last night. Like all the planets its a blurry blob in the 2.5mm eyepiece. I guess this is due to atmospheric haze but I'm not sure. Maybe the setup is still not quite there. Aligning the primary mirror has been a ongoing series of trial and errors. I feel that all scopes should have a simple and convenient way of precisely collimating without having to use a false star and looking concentric rings, better still an automatic mirror alignment system. Still, even if I keep fussing and continue tweaking the mirror, I think that's as good as it'll get with this type of scope. Seeing details on the moon and blurry planets is still cool but galaxies and nebulas?
