How do I attach telescope tube to eq dovetail mount?


You first have to get 2 tube rings. These must be the right size for your scope.

http://www.optcorp.com/orion-116mm-id-orion-telescope-tube-rings-7372.html

They will have hinges and clamp screws and at least one other hole for attaching to a dovetail rail. Then you need a rail, sized appropriately for your scope. They come in several lengths and 2 geometries, Vixen and Losmandy. Almost certainly you will need the first one.

http://www.optcorp.com/aa-vdup11-vdup11-vixen-style-11inch-dovetail-universal-plate.html

There are some scopes with very fat tubes, like Schmidt-Cassegrains, where the rail attaches directly to the tube fittings.

Cannot find any info on "Short Tube Catadioptric Telescope". Any info available


Many of the telescopes this company sells are Catadioptric, meaning they use mirrors and lenses to shorten the tube length:

I've used one of their telescopes for 20 years. Good.

Can you tell me where i can buy an image erector, thanks


Yes, but it will probably cost almost as much as you paid for the scope:

here is one:

All astronomical telescopes show upside down images, it's normal. The erecting diagonal is only used for terrestrial day time viewing, of land objects.
