He's asking $120 for them which is $50 more than Bintel's, my head is starting to spin.  |
First don't go to him, he is way too expensive and not trustworthy. I and several others here in SA have had bad experiences with him. He always adds 30% onto everything and sometimes as much as 50%.
To check if you laser or a laser is collimated. Make a jig with two "v's" and use these as a craddle to hold the laser. Then turn the laser on and about 15 feet away have a door with some white paper stuck to it. Point the laser at the paper and rotate the laser a little at a time. Go and make it after each rotation. You will see if it is collimated. Most lasers for this type of thing have collimatino screws.
However, I recommend getting a barlowed laser as this is more accurate and will present the centre dot image at the face of the barlow. It will not shift when you rotate the laser, thereby removing the need for great collimation of the laser.
