    Quick question Wayne, was the internal beam shot taken before or after alignment? It looks like the green could be better centred in the red beam after the red dichro. Don't forget to align in the X and Y axis. I find that part is easiest to do with some fog and actually align the beams (you can see if they are parallel roughly too) in the air, rather than do dots on dichros.

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.

    Hi mate, yeah it was out. I have re-adjusted several times since the photo. And yeah, I used fog, it does make it easier to see whats going on.

    I need to take this in to work and align far field in the warehouse at much greater distances than I can achieve here at home.

    Cheers!

    Looking good Wayne. What I do for far field alignment is to take a 10x concave mirror, a small 4 inch one for personal facial issues, acne and such, and project a beam on it. At 10 feet it simulates a good 100 foot throw which is very good for matching far field alignment.

    Good tip!

    I have been using my wives facial mirror to double the length of my lab. Flip it over and it magnifies all ugliness! I never thought to use it that way!

    Great idea but I think Wayne is just trying to have a good excuse to take his projector to work.
