Thanks for the input lads.

Chris that was some job they did on that rear window! I had no idea it took that long to polish space telescopes.

Maybe haze wasn't the right word to use but I did mean when the light catches it, it can be hard to see out of. I will have a go over the weekend of cleaning the windows and claying to them too. Hopefully that will make a good difference to it. Hopefully at the meet next week I will be telling how much better it is
