      I have four Tele Vue eyepieces (8-mm Delos, 13-mm Ethos, 27-mm Panoptic, and 41-mm Panoptic). All four are outstanding. I use them with my Celestron C-5+, Celestron CPC-800, and Celestron CPC-1100HD. I once put the $600 Ethos on my $50 75-mm Celestron FirstScope (Galileo Anniversary Edition, which I bought to decorate my home office). The combo actually worked, even though it is impractical. 🙂

      I had a televue 101 and a televue pronto. I had had many televue eyepieces over the years. I had everything stolen in 2018 and had to start over on a shoestring. No more televue refractors, 31 nagler or type 6 naglers and powemates, but I do have a televue paracorr, and old original smoothside 7mm nagler and 32mm plossl. Much less televue than I used to own. I have mostly older meade series 4000 ultrawide eyepieces, older meade series 4000 super plossls, and more modern but excellently executed Chinese clones of the type 5 nagler (28mm UWAN type 82deg) and ethos (20mm XWA), and a couple vixen LVWs and the 24mm explore scientific clone of the 24mm televue panoptic. I previously owned 4 of the meade 5000 swa versions of the same eyepiece, 24, 28 34 and 40mm.
      But the wide field view of the 31mm nagler in the televue 101 wide field flat field refractor was just insane in dark skies. If I could kill anyone with my bare hands and get away with it, it would be the tweakers that broke into my storage and took it all from me. And they got SO much more than that.

    to be clear, this is for a Cassegraine-type reflecting telescope; i'd say most reflecting telescopes are of the Newtonian type, which has the secondary mirror bounce the light off to a side hole in the tube (rather than back down the tube) which is where the focuser/eyepiece is.

    • @serpent77
      @serpent77 2 года назад +2

      Basically the primary mirror (the one with the hole) collects light and through it's curved surface reflects and focuses the light on the secondary mirror at the front of the telescope (the mirror they kind of glossed over in the video) that also has a curve to focus the light down to the hole in the primary mirror to the viewer/camera/etc. The light kind of makes an "N" path from the right side and following it all around the telescope body.

    • @2Fast4Mellow
      @2Fast4Mellow 2 года назад +1

      A telescope works similar to a satellite dish. The large outer disc reflects that light back to the small receiver in the middle facing the disc.
      Using the knobs you change the distance between the outer and inner disc in the same way you can focus the beam of a magnify class on a piece of paper.
      In the 'ol days you had these film/photo projectors that put a light behind a film and the image was projected on a mirror, than the image of the mirror was reflected on a canvas (or wall). Because of this reflection photo's are shown upside down...

    • @John_Ridley
      @John_Ridley 2 года назад +1

      The area where the hole is wouldn't collect any light anyway, it's in the shadow of the secondary mirror. Keep in mind this is only one of dozens of different styles of scopes. Since they didn't mention a front corrector plate and it has a spider secondary, I'm assuming this is a classical cassegrain or similar. They're actually not very common. The most common types are newtonian, Schmidt-Cassegrain, refractors and Maksukov-Cassegrain, probably in that order.

    how can anyone teletransport from one planet to another at a further galaxy I mean only God can do that since he's invincible, there's a lot of obstruction on the way, stars would burn you, on the other side I don't know how telescope can pass through the stars without planets or stars blocking its view.

    At 4:38 you can see the lint, hairs and other FOD on the mirrors surface. A semblance of a clean environment when assembling them goes a long way.

      That's not FOD.
      FOD stands for foreign object damage and that is not applicable here.
      For assembly you don't need a clean room as long as you use gloves and proper post assembly cleaning.
      Especially for this level of telescope

      I saw a video of Canon factory, where they assemble one of their large zoom lenses (like 1000mm size),
      and the factory workers did not wear globes when they assemble those lenses either.

      It need to cool down to get the sharpest images.

    • @maximus9812
      @maximus9812 7 месяцев назад

      Differences in temperature between the inside and outside of the scope cause air currents that distort the image. So you want the scope to cool to ambient temperature before use. Closed tube scopes like the one in the video take longer to cool, so the fans help.
