Hello there

I received my laser collimator today (one of those $30 ebay ones) and it did not quite work as I wanted.

I would adjust everything just so and then take the collimator out - when I would then put it in again right away the laser would be off on both the primary and in the collimator target.

In the event of user error, here is what I did:

1. Insert collimator (already turned on to the lowest setting) with the target facing straight down
2. Screw it in tightly with no play whatsoever
3. Adjust secondary mirror with small allen key until laser is in the circle on the primary
4. Adjust primary until laser disappears in the target hole
5. Take collimator out

Then, as mentioned, after re-inserting the laser was way out of the circle on the primary. Then I adjusted it again, removed it, reinserted, and it was off again!

What am I missing?

Thanks!
