It does quit functioning when it's cold, however. I'm not sure if it will last long enough to get full 3-star alignment in cold weather. (Lately, I've been viewing from my partially obstructed 2nd floor deck, and I just do a 1-Star Alignment and view nearby objects.)
The deck isn't stable enough for high mags, but it's fine for low to medium magnification. To help make the system as stable as possible, I keep the tripod legs retracted and sit on the deck to view. The only problem with this has been the straight-through finder, which is unkind to the neck at that height.
The GLP has worked like a charm for this purpose. I'm hoping that by popping out onto the deck from the warm house and doing a quick alignment, the it will be okay all winter.

I'm using the Z-Bolt BTG-2S. Stable brightness, solid construction. So far very reliable. Also has an always-on button, or alternatively a push button on a short flexible cable - both are far better than the usual button on a regular laser.
I actually have two - one stays on the scope, on an Orion bracket (for star hopping), the other in my pocket (to point things out when I do a demo).

Try rubber-banding a chemical hand warmer to it. That will keep it going all night! Hand warmers are cheap, usually around 3 for a buck.
Great idea, thanks!
I'm curious: Does anyone know if the Z-bolt performs better at low temps?
