Ingredients : 1 standard laser collimator, 1 barlow and a white paper target over the end of the focuser tube with a hole to allow the laser light through.
You see an image of the centre donut reflected back onto the target and adjust to centre it. This technique overcomes the usual shortcommings of using a laser to collimate.
Thats a nice read
Thats an easy to understand page and a simple way of improving the laser technique.
Still haven't decided which way I'm going to go in the regards to tools, so I'll be waiting on your report.
