I just received and installed the Rigel Quickfinder. I wouldn't ordinarily give something 5 stars without the first use, but I already know it's worth a 5 star rating. Why?... because now I won't be tempted to order and try to use a green laser pointer to locate objects in the night sky. It's too much hassle to worry about newly established, possibly local, regulations regarding the use of laser pointers, and, too, using one in a remote area is just a signal to the uninvited that maybe someone is camped out using an expensive device to watch the heavens, and maybe it might be fun to go see if they're alone, if they have a nice car, and maybe if it's worth sneaking around to capitalize on an unguarded moment. Paranoid?... Why yes, I am.I'll also use it from home in my large back yard, and I live only a few miles from both an Air Force base and a large municipal airport. Even though I'd never point it at a passing aircraft, some enterprising pilot, even one not remotely aimed at, almost surely will see it at some time and go "Boy Scout" on me just to turn in a report and do his duty.Too, I already know that using the Quickfinder will be so easy, so very easy. I know this because I've already mounted it on the rear end of the tube of my Orion SpaceProbe 130 ST, and from the relative darkness of a garage I've zeroed in the viewer window with both the attendant finder scope of the Orion and the center field of the telescope itself. I used twigs at the top of a tree about 100 ft. tall, and the tree was about 300 yards distant, so I know that putting Andromeda in the Quickfinder's bull's eye will render a centered image of Andromeda, or anything else I want to locate. No need for a laser... no need to worry about Boy Scouts... unless I run across some who'd like to take a look in my telescope.I'm less than an amateur astronomer, and on a 1-10 scale, I'll never get above maybe a 3, or 4 at best. However, as a sufferer of back pain, I'm a professional, and I know I didn't want that Quickfinder mounted on the front of the telescope, since my big fat head and the telescope tube would get in the way of aiming and put me in ridiculous and painful contortions trying to do it, especially if some object high overhead is the target. No, no need to do that if the Quickfinder is on the back of the telescope, where there is infinite space for the head and eyes to get behind and aim that wonderfully useful finder, unless of course one couldn't accomplish the aiming without sticking their head in the ground. Take note that the closer the eye is to the Quickfinder, the smaller the red target bull's eye will be, and you'll see on the attached picture that I put it in a place where the view splits the difference between the telescope objective tube and the attendant finder scope that came with the Orion. Aiming it is a joy, like using a machine gun on the heavens.Put that Quickfinder on the back of the telescope. Use a couple of 24 inch cable ties (remember!... Pi times your tube diameter plus another 2 or 3 inches are needed for the overall length of the cable tie), one over each ledge/end of the Quickfinder. Later you may want to use that position permanently, or another position, and maybe then you'll want to use the double-sided "until death do we part" sticky tape. I don't want anything to do with that stuff so I used the cable ties, and they work perfectly. If somebody wants to know why I mounted my Quickfinder on the back of the tube and made it look like I'm a ding-dong, then they can shove off, because I've already told you why I did it.
