It looks like there are three parallel lasers on the source/target disc from where their beams enter the optical tube. The laser beams return to the source/target disc, placed quite close to the OTA and by noting the position of the returned beams, you can make comfortable adjustments to the 2dary holder to collimate your ‘scope.
No price yet, it seems 1st production units will be available at the end of April 2010.
Get one H0ughy, you know you need one!
