Having used the little ETX90 for a few months, I caught "aperture fever" for a while, and bought this much larger instrument! ;-)
It came with an EQ5 mount (which I still use), but needed two counterweights to balance it, so the supplied lightweight tripod was really too "whackery" for it, so I got an old wooden surveyor's tripod and adapted that instead.

The optics were good, and the 1000mm focal length was a good compromise for wide-field viewing and planetary observing (with a Barlow lens), and it was fitted with a 9x50 finder-scope as standard: this makes locating faint objects much easier than with a 6x30 or "red-dot" finder!

I made an "eyepiece projection" adaptor for my digital camera, and got a few decent pictures of Saturn with it (see the Gallery).
The draw-tube could accomodate 1.25" and 2" eyepieces, and also had a "T2" thread for mounting a camera.

After a couple of years transporting it back and forth between Bristol and Bolton, I sold it and bought my much more compact 8" SCT.
