I'm pretty impressed with this little finder. It's simple to calibrate, fits the mount on my Galileo telescope (because they're the exact same telescope) and it's got some nice features. Two brightness levels is handy, especially when you're trying to view smaller objects. You can turn down the brightness and go. Now, I've seen complaints that the dot is large, which is true if you sit at the rear of your telescope. I prefer to look down the sight while I'm close to the focuser. The dot's much smaller and gives you much better accuracy. The build seems reasonably solid for something made completely out of plastic and it mounts nice and tight on the telescope. Overall, I'm very pleased.
The Celestron tripod is a great choice for relatively small telescopes. I bought it for use with a MAC90 after first trying a camera tripod. The camera tripod was simply not sturdy enough to hold the scope still, particularly when used with higher magnification. The Celestron Tripod comes with no instructions, but set up is pretty straight forward. One negative is that there is no easy adjustment for the elevation control large movements. The two knobs on flex cables provide fine adjustments of both rotation and elevation. I found that I had to loosen the bolt in the head which controls up down pivot to make it easier to make the adjustments which are then done by pressing on the scope. Once in position the knob allows for fine tuning. However there is no way to 'lock' the position without getting out the wrench again. Despite this limitation this is still a signficant step up from a camera tripod for scopes particularly for astronomical use
I use this zoom eyepiece in my Meade ETX 80 and my Orion XT8i. It has become my default eyepiece. It is not quite as sharp and clear as my Meade or Orion Plossil eyepieces but it is fine for most cases. If I want to spend detailed time on a subject then I might use this to find the best mag then switch to a single mag. But may times this is the only eyepiece I use, sometimes combined with a 2X barlow.
