2" AstroSystems Laser Collimator, has original box, see link
https://www.astrosystems.biz/coltlsm1.htm $100 + postage.
This collimator has just been excellent, adjust primary and secondary in moments using the collimator +/- attached Barlow adaptor, it was probably the best 'tool' I have ever bought and meant I had good collimation every time I used my scope. Originally bought from SDM, who don't skimp on quality.
Selling because I'm in the process of selling my 10" dob, having bought a more portable 8" NexStar. Will post however you like, you pay only the postage itself. If you are in Adelaide, you are welcome to come and pick-up instead.
