Hi All!
I have a collimation question. I am collimating a 14.5" Starmaster (F4.3). I have the Tectron tools (sight tube, Cheshire & Autocollimator) and a Kendrick 2" Laser.
Here's the deal. The mirror is center marked with a red dot and white circle. I use the Tectron tools. I have my wife help with the final adjustments to the primary while I look through the autocollimator. I can get the "white circle" images pretty much overlapped. Yeah!
Not so fast. Then I check with the laser. The beam doesn't fall on center of the primary - slightly off, ditto the return on the secondary and more so for the return on the laser.
I am pretty darn sure the laser is collimated. I have put it in a "V" and rotated the laser, while watching its image about 30 feet away - no circles, it stays put.
I have viewed through the scope after collimating with the laser and with the autocollimator. Planetary images have been good both times.
They cant both be right? What gives? :S

Thanks!
