Recently I decided to take the leap and get a Z-bolt laser (Green, Astro version, low temperature model) and the mounting for it.
I got it mounted where I had my previous laser. And since it had disturbed my Guide Scope and Red Dot sight, a full aligning was in order.
In the past, my laser was more of a novelty for the Grand-kids. "Whatcha lookin at, Grandpa?"
Zap! The green beam shot skyward drawing their attention into Space.
Stepping up to the Z-bolt, we have a very handy aiming device that has shown it's worth especially during alignments. (Modeling in Losmandy terms)
Once I got my Red Dot zeroed, and the Z-bolt zeroed, and my Guide Scope, all zeroed to my Main Telescope's aim point I was ready to go aligning and hunting.
When the mount chose a particularly awkward high zenith star, I didn't want to do the contortions to get to the Red Dot sight.
But switch on the laser, bring the beam onto the star, and Wa-La, it was in the telescopes FOV for fine adjustment.
Hey, I LIKE this thing! A really nice option to getting bent up and trying to peer through my Red Dot.
I make sure that if any aircraft are in the vicinity, I'm mindful not to light it up in case they might see it. A private business jet flew over on it's way toward one of the Los Angeles airports and I shut off the laser I was columating on Polaris during my initial setting up.
I don't know if they saw the beam up there, but a little later our local sheriff's helicopter did a fairly low Look-See by me. After they were past, I did a few more test firings on Polaris, and when they returned Southward of me I kept the laser on, my red headlamp, and of course my Laptop was glowing away. Nothing to hide here, Deputies.
I advocate sensible laser use. And I believe they know I'm down there just fiddling with my telescope. At least, Sargent O'Malley of the FBI hasn't come knocking on my door.
But the adjustability of the Z-bolt mount, the choice of momentary or stay-on beam, and not having to be a contortionist to look through my Red Dot. The mounting is quite precise if you need to remove the accessory for casing your telescope for transport.
And it came with rechargeable AAA batteries. Still waiting for the OEM disposables to go belly up, then I'll start using the rechargeable batteries.
But the Z-bolt has found a place in my gear and routine.
I'd recommend it to anyone looking for a primary aiming device where you don't have to get a kink in your neck.
