Frequently Asked Questions (FAQ)

How Does it Work?

The tool takes a series of exposures as fast as the camera will allow. The results are downloaded from the camera and displayed on the screen instantly. There is a focus zoom tool that allows you then to zoom in on any part of the image. Ie a bright star. There is also focus metrics displayed about the star. All you then do is tweak the telescope of focus after  each image until you see a nice crisp image of the star you have zoomed in on and have the best focus metrics.

What Camera's will the full features work with? *

It works with D60's, 10D's  and EOS300D Digital Rebels.

It works with ANY digital camera provided you have software to download the images from your camera to the PC after each exposure.

I have a new laptop that does not have a parallel port or serial port . Can I still use the Serial cable somehow? *

Yes. You can get a USB - Serial Port Port Replicator, then make or buy a serial cable. The software has been designed specifically this feature in mind.

 (NOTE: The parallel cable design does not work with a USB - Parallel cable (DB25) converter. These are designed for printers only)

Do I need a Parallel or Serial cable to use the software ? *

No. To use the focusing features, all you need is the USB cable that came with your camera. If you want to use the Capture features for exposures longer than 30 secs to control long bulb exposures, then you do need to buy or make either a serial or parallel cable.(*aplies to Canon DSLR Users only)
