It is with great regret that I have to sell my Astrotrac for the purpose of funding other accessories (dam you expensive hobby!). I purchased this in 2012 directly from Astrotrac in the UK along with the Astrotrac Polar Scope for ~$1000 at the time. Not cheap I know, but a fantastic piece of kit that has served me extremely well. To be specific this is the TT320X-AG version, i.e. has the autoguider port. You can see some of the images I've taken with this here:

As already stated I purchased the Polar Scope with it as well, which to be honest I hardly used (I still can't find Sigma Octans!!!). Nevertheless it's included for those with better visual acuity than I. The red light illuminator for the scope will need replacing as it has stopped working. You can get a replacement (such as this
http://agenaastro.com/agena-cordless-illuminator.html) for ~$30. I hadn't purchased a replacement simply because I didn't use it.
The astrotrac is powered by either 8xAA batteries or another battery source with cigarette input.
I'm selling the total kit for $600 pick up from Sydney, willing to ship at the buyers expense.
I also have an Induro Bhl1 ball head and Manfrotto 410 Jr Geared Head which I used with it and will be selling separately. If you're interested in purchasing these as well let me know.
