Thanks all,
Sharkbite how do you rwmove the primary mirror with the 6 screws? As by the look of mine that will only release the mirror inside the tube but you cant get it out without removing the cell itself which is held in place by little nuts inside the tube and bolts from the outside! It seems such a crappy design becouse on my other saxon scopes they are just scewed in from the outside so you simply unscrew them and remove the mirror cell, but with this one you have to have a hand inside the tube to remove and then replace the cell as you have to hold the nuts

Thanks
Dan
