This 3x Barlow is an OK value for the money. I would have liked to have had a clamp ring feature instead of just a setscrew to prevent misalignment of the eyepiece, but what can you expect for the price? I would recommend this product for those willing to accept the compromises.
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
