Focusing systems
THis is a very interesting point you make Troy and it is very true. I suppose that is why a robofocuser will set you back $500 and the Skywatcher $90. However is you are interested got to astronomyorg.co.uk also hitecastro.co.uk
There is a unit which called DCfocus controller. You connect the skywatcher motor up to this then it is connected to your computer. While it is not a stepper motor it is recieving rave reviews. Apparently you control the whole thing from your computer and can focus with very minute steps and accuracy.
Skywatcher moter and hand controller $90
DCfocus $99
You need nothing else. Sirius optics have just been appointed distributor in Australia. I sent a couple of questions to the UK manufacturer and got a reply within a day.
It's not as good as JMI, Moonlite ar robofocuser but affordable if you are on a budget, fortunately for me I'm not. I just have to way up the overkill factor. I am only using a Skywatcher ed120 black Diamond there is a limit to what you canm expect to or need to achieve.
All good food for thought, especially with a good Aussie dollar.
Cheers and Thank's
