Yeah, and VOB has a lathe. I thought he might have shortened it and cut new threads. Now that I think about it, it doesn’t really make sense for him to cut down the double length tube.
5 meter is bit short, you may be off a few percent, some people even claim that 20 meter is not enough for good collimation and thus correct measurement. And technically they are correct.
But then I claim that the error of their luxmeters is more significant than the difference of measuring between 5m and 40m.
Moreover, the focuspoint of not all GT’s is at infinity as it should be, so if you have a very unlucky GT, the best collimation could even be at 5m.
So I’ll test it tonight and if the cd drops off after 5m it’s not a good focus? I damn well hope it isn’t cause that will bother me is there any way to fix it if it’s out of focus?
And if it changes anything I switched my led to a 5700k
Very nice, I have on of those optics myself but have not had time to figure out the mounting setup, I figure I will 3D print it but just have not had time.
