200p dob isn’t focusing.


Recommended Posts

Hi

i decided to take my scope out this morning to see if everything is ok with it as I hadn’t used it for over a year. While I was putting in the eyepiece I realised it wasn’t focusing.I have it lined up with an Ariel ( not near the sun) and when I try to get it to focus it simply won’t move. I have tried loosening the focus screw it works until I put the eyepiece in.  Photo below is how I have it set up.

Did you accidentally lock the focus with that central screw at the base?

I’ve loosened it up after I posted  and it’s moving up and down now but the Ariel still isn’t in focus. Do you think it needs Collimating? I haven’t used it for a long time.

Hi,

If the ariel is on a roof close to your proximity you wont get focus. You should try to focus on something 100-200mtrs away ideally.

Hi Baz, that was the problem. I had used that Ariel before and seemed to be ok but used the top of a tree and managed to get it in focus. Thanks for the help.
