People, you are missing out on a bargain here just because it's cheap. I had two for sale and here's what the buyer of the other one had to say after he'd had a chance to try it out:
"In the meanwhile I’ve been very pleased with the little Celestron I got from you. Since I have a Meade 4mm it’s pretty hard not to make comparisons. The Meade is a little warmer, or the Celestron is a little cooler. The eye relief is about the same. The sharpness and contrast are about the same. The AFOV is much larger in the Celestron. The Meade is like looking through a straw in comparison. One of them is lying about the focal length. The Celestron gives images that are about 1/3 larger in scale. Either the Celestron is closer to 3mm or the Meade is closer to 5. I’ve got a Pentax 5 on the way so I’ll be able to make a better judgment on this soon. Definitely a good deal at $34."
After that, I ought to raise the price, but, I won't, since I just want someone else out there to use and appreciate this little gem. I don't need it since I've got a 3.8mm Pentax XP, 4mm Meade RG, 4mm Zeiss-Jena and 4mm TMB.
