Re: Checking Collimination of Big Eyes
I can show you this procedure the next time I see you.
Just bring the glasses with you and I can explain in detail.
You can do it with the moon, however I have found the straight horizontal and verticle planes to work better for me.
When using the moon and centering till you get one picture at such a great distance, the optics will be off when going back to the normal viewing yardage of 500 to 2000 or a bit more.
It works the same when using a collimator up close. You will be off when going out to the normal viewing yardages.
The Kowa company is having the same problem with their new Kowa "Highlanders".
They can't seem to get them collimated from the factory and they are using a close up collimator. I know a fellow who has sent his back three times without satisfaction.
They have to be adjusted internally not the way we can adjust ours, externally.
