It will not focus. I have used several eyepieces

It WILL focus -- put the eyepiece with the LARGEST number in it into the tube........... DO NOT USE the 2x or 3x Barlow.......... this eyepiece is the LOWEST magnification.

Take the scope outside during the day and practice focusing on a distant object at least 100 yards away. If you are expecting 650 power forget it-- you will only get about 120 power as the maximum usable magnification, with that aperture 80mm scope.

you need to use that flip barlow as a spacer to reach focus

Yes, I did type mirror/s I know....Your problem still could be that the lenses need collimating....just thought that I should pick up on my own mistake. Cheers.

It sounds to me like your mirror/s need collimating. It might be worth getting in touch with your local astronomical society. They will probably have someone onboard that will have a collimator and what's more they'll show you how to use it. It would be silly to buy a piece of equipment like that for one use, on the chance that that is your problem. Most societies have a "public night" call or email them and then take it along. I have no doubt that they will be glad to help. Hope you get some satisfaction!
