Hi,
Yes, just got one up from Bintel Melbourne (Sydney store was out of stock). I asked about the need for adjustment of the unit so the beam was true to the housing, and was told "Yes, we just did that".
It is easy to use, and comes with instructions which are clear enough, but after much research on the Net I decided to check the alignment of the unit. Attached is a photo of the little jig I built for the purpose.
I found the laser was 11' 27" out, or a 4 cm circle of wander at 6 m. I don't object to this, because there is no telling what knocks it took in the post, and this astronomy game seems to have a huge element of DIY and self-reliance. It just shows that it pays to check.
After adjusting the laser unit to true, I found that the telescope (a 200mm Bintel Dob) had been waaayy out. My next little project is to try the Barlowed laser collimation procedure of N. O. Carlin. It looks good.
Regards
