As I have sold my telescope and eyepieces I will need to sell some accessories I guess.
So I have used this Hotech 2" Cross Hair Laser Collimator for a few years now and reckon it is probably the best collimator on the market (IMHO).
Sky and Telescope Hot Product 2009!
Simple to use, and I have found it to be completely reliable in results.
It incorporates a self centering barrel adjustment to increase fidelity.
The centre barrel has expanding rubber rings which eliminate the need for a gap from the clamp thumbscrew. A Self centering and paralleling mechanism.
The crosshair laser can easily help to adjust the secondary mirror to point the laser on the exact center dot. During the final primary mirror collimation, the returning laser dot often hides in the laser exiting hole making it hard to see if it is at exact center of the hole. But, the crosshair will visually guide you to center the laser dot with ease even when the center laser dot disappears.
$100 pickup Wyong region NSW Central Coast or plus postage (say about $10). I think they retail around US$160 plus postage.
I'll also include a manual collimating eyepiece Saxon brand as I recall for free.
Some people say it is good to check with the old traditional method. I like to just make sure occasionally, but it is always good.
Also it is also probably better when you need to get/check the secondary is centered in the viewing channel if you think that may need adjustment. That's another $70 value included.
Sorry, the photo is a stock photo for the moment.
