Q: 5. What I feel that needs to be better explained about eyepieces and focal lengths as in 6mm or 25mm is that the opening is tiny for 6 mm as compared with 25mm that is wider . The lower the focal length the difficult it gets to train your eye throughthe opening due to its tiny opening. My child experience with my first kid telescope that came with 6mm and 25mm eyepieces told me that 25mm is more enjoyable to use despite lower magnification than the higher magnifying 6mm which is so restrictive in the opening for my eye to keep peeking through as steadiily as I can. I think that a minimum of 10mm is acceptable to me or maybe 12mm. . Am I correct?

A: Yes that is correct. 10 or 12mm will be okay. It also depends on how large of an aperture your scope has. The bigger front opening of the scope the brighter the image.

Q: 6. Is this a good eyepiece and is it compatible with the Celestron Nexstar 105 GT telescope?

A: Televue Panoptics are excellent eyepieces. Very sharp, clear images. To determine if an eyepiece is compatible with your telescope you first need to calculate your telescope's Maximum True Field of View, then calculate the eyepiece's True field of View. Eyepieces that have a True Field of View greater than your telescope's Maximum True Field of View will cutoff the image and have chromatic aberrations around the edges. Generally speaking, it does not hurt to go a little over tFOV with quality eyepieces, but the more the eyepiece's tFOV is over the telescopes's max tFOV more of the image is cutoff and the worse the chromatic aberrations get around the edges.There are several very good free eyepiece calculators available on the web to calculate Max tFOV, and help determine eyepiece compatibility.

Q: 10. Are the Delos eyepieces par-focal?

A: Yes they are par focal with many other Televue eyepieces. Go to the televue site and look at the chart of eyepiece specifications. Scan the column 4G . Eyepieces with the same letter in that column are parfocal. So most of the Delos ep's have the letter B . You will see that some other types of TV eyepieces also have the letter B . All those are par focal.
