Brill thanks Carol, much as I thought. It will certainly be easier doing it that way than unscrewing everything.

I have a few improvements I want to make to my Skywatcher but I had to wait so so long to own a telescope I am really hesitant to get in there and get dirty in (unlike how I usually approach everything else!) in case something doesn't go right.

This is going to be so good

! Thanks for all the encouragement - it's great when you read about things that can be done and, hey, other people are doing them why not me?!

Now ... if only we had Staples here!
