Help needed

[Les]

Last night was one of the few nights I've been able to take the telescope out and I noticed that the focus is still off. Instead of a pinpoint star, what I saw was like a ring. With the telescope I only got one eyepiece - a 26mm QX. The scope has a 254mm apeture, a focal length of 1270mm and a focal ratio of f/5.

I thought I had it sorted when I turned it on the moon a few backs, but seems as though I didn't. Can anyone offer advice or help?

Les,

If you have a barlow put that in and see if you can get focus, if you can then the scope / focuser does not have enough in-focus.

Whats is the is the scope and setup, i.e. diagonals etc?

I think you said it's a 10" Lightbridge.
Was it new ?

If you haven't got a Barlow (a tube that magnifies the eyepiece) you could try getting the thing as close to focus as you can then loosen the eyepiece and gently ease it in or out of the focuser to see if that improves matters.

The telescope is brand new but didnt come with a Barlow. In a few weeks, I should be getting an eyepiece set which does include one. If it helps then I could just go for the cheaper eyepiece set without one and get the Barlow now.

Stick to the better eyepieces and try moving the eyepiece as I said earlier.

Has it ever managed to get in focus or is this the first time you've tried it - Might be worth speaking to the supplier, it could be damaged

I'm positive that it was ok when focusing on the moon - but that was done @ about 1am sio maybe I was wrong about that. Will try adjustments on the next clear night.
