Thanks everyone for your help. Absolutely spot on about the adapters. Helps my understanding of a focus point too. Have now worked out both the 2" and 1.25" adapters that needed to be in place first to allow correct distance to eye.  The hills have come into perfect focus. Also I can hold off on the glasses for now as I really did wonder if my sight was going slightly : ) )

Ahh understood. Yes found that now. I'll try that now - thank you.

Hmmm maybe I'm not setting this up right then. I've taken all the adapters etc. off and taken step by step pictures of how I set up the eye piece. This holds the 1.25" 10mm.

Am I getting this wrong?

Thanks for coming back to me Cornelius.

To be honest, I'm not sure. I've attached a picture here which shows (I think) a 28mm lens with the 2" adapter and also a 2" to 1.25" adapter for the 10mm lens. The 28mm just goes straight into the eyepiece of the scope. The other one allows me to swap lenses once the adapter is in place.

I had a telescope some years ago and recently got back into the game with a 6" Skywatcher.

Attempted some observing a couple of nights ago and could only see a complete blur through my lens. I tried a 10mm, 25mm & 28mm lens. The scope has a sweet focuser with a fine tuning knob to boot; but no matter how much I tried, it was always completely blurry.  I could see Polarise perfectly thought the built in polar aligner on the scope of my mount as I was questioning my own eye sight at one point (still haven't ruled that out).

So I concluded the scope needed collimating (it's a 2nd hand scope). Purchased a laser collimator and completed the alignment. Then took it out in the day and pointed it at some hills about 3 miles away.  Still completely blurry no matter how much I focused.

I don't know if the metal fins at the very front of the scope are meant to be adjusted as part of the collimation, as the laser collimator doesn't cover that. Not touched that part of the scope.

If I take the eye piece out and stand about 8-10 inches away, look into the scope i.e. at the secondary mirror without a lens in, I can see the hills albeit upside down. It's only when I put a lens in, any lens it seems, and adjust the focuser from minimum to maximum, I get a consistent blurry image. You can make colours but that's it.

Stuck now - any advice would be appreciated.
