Excellent, thanks for the replies, if I'd of known the thing was mounted the wrong way round I wouldn't have posted a pic 🤣.
I've ordered a cheap 1.25" diagonal (Here) and the (Celestron eyepiece). Hopefully that gets us going. I've a good view at the house so hopefully the eyepiece is good for terrestrial viewing too.
The handset is still there. I'll use batteries for the time being, and I've an upgraded finder. Telrad I think. The more I type I'm remembering that I spent quite a lot of money on eye pieces and different bits. Time to get the bug back, and hopefully we'll bump into each other again. Plus I promised pints 😀
