I see a variety of laser collimator tools.  

 

What collimator products are RC truss scope owners using that work well?

 

thanks,’Bill

10" GSO carbon-tube (not truss tube) RC.  I've used several laser collimators, including my favorite - a Howie Glatter 2" with holographic attachment that has a small center dot surrounded by 9 or so concentric circles. About a year ago I dropped some serious $$ on a Takahashi collimating telescope and use that exclusively now.  I always follow the collimation process with a star test, although usually it's good enough that no adjustment is necessary.  If it is, it's pretty small.

My preference is the DSI instructions. Equally suited to truss or tube telescopes.

I use the Tak scope for my CF which gets me really close, for touch up the DSI method. For the GSO RC only the DSI method produced acceptable results, the Tak was off. The Hotech advanced CT is spot-on accurate, but setting it up correctly takes longer than performing collimation on the stars.

+1 to what Rasfahan said!  I use a Tak collimating scope and a Howie Glatter on my CFF RC with good results along with the DSI method.
