Hi Folks, just joined. I've never done astronomy before but I've been given a Celestron Astro Master 114. It originally was bought as a present for a teenager but he never took to it and it languished in a shed for a few years. I've tried setting it up but I don't get very sharp images and it seems very prone to vibrations when turning the knobs. It's also really tricky to line it up to things - even the moon, though I thought I'd got the star pointer set up correctly.
I suspect I need to take the mirrors out and clean and collimate them then ensure the mount is moving freely.
Sorry to sound so dumb. I suspect if it was new I'd have been up and running by now, but I think the original owner messed things up when originally assembling it, so it would be good to know where to start to get it right, without making it worse.
