Celestron 8" f/10 SCT

I've had this since 2003, and it's still my main instrument.
I already had a motorised EQ5 mount, so I purchased it as an optical tube only.
I soon found that the supplied 30mm finder scope was inadequate for locating objects and star-hopping (remember that I have no Go-To on this mount), so I replaced it with a 9x50, which is a big improvement.

The basic telescope has a focal length of just over 2m, but I can add a Barlow lens for high-magnification planetary observing (and imaging), or a focal reducer for a wider field of view of big galaxies and clusters etc. Obviously its performance with these add-ons is not as good as you'd get with dedicated 'scopes, but at least it allows me to look at all sorts of objects with the same instrument.

It's fairly easy to move around: the optical tube, tripod, mount and counter-weight can all be carried separately, but I can still just about carry the fully-assembed kit across the lawn if I need to.

I finally swapped my EQ5 for the CG5-GT model, and a less "whackery" tripod!
