Hi guys,
I was just flicking through the ads in the December issue of Sky & Telescope (US version) and there is an ad from Hotech with a new method of collimating a cassegrain type scope using a laser. I purchased one of their new self centering lasers, but it really doesn't work for an SCT very well. This appears to be something different with alignment being performed with the target just a metre from the scope. I thought I would just point it out to anyone who may be interested in the concept etc.
