There's a Nexstar 102GT for sale in the classifieds for $160.00, tube alone $100.00 and it's not in very good condition. I wonder if he knows.

some say that if you have a digital micrometer, you can line up the thinnest part of one of the lenses with the thicker part of the other. I didn't have one and went the old fashioned way.

I kept the flint stationary inside the tube while gently loosening the screw on part of the plastic cell. This really sticks the first time you loosen it so be prepared for the lenses to jump out at you. The lenses should not be have this tightened down so hard anyways as it will pinch the outside of the optic. Afterwards I tilt the tube down to let just the crown pop out. I wear rubber gloves to cut down on fingerprints. I marked the crown with a perminent marker for reference(12 o'clock position.) Then since you have astigmatism at your current spot, rotate about one hour on the clock face. Then you retest. Repeat, retest, repeat retest, etc. When you find your sweet spot, which might take a while, you keep it there. Next time you remove both lenses for cleaning, you want to mark the flint where it lines up with the line on the crown.

I hope this makes sense. If not I am around the boards a lot.

Is there a link for the $59.95 price? The one on the first page does not work. On their website they have it listed for $119.95.

I think the sale is over. If you click telescopes by manufacture, Celestron, you'll see that they are back to their regular price.

Congrats to those who picked one up at the sale price.
