  1. Noob here, forgive with my ignorance On a reflector telescope, the achromatic aberration can only come from the eyepieces, correct? Since all eyepieces are made of lenses, they all have achromatic aberration, so, which eyepiece types have less (or correct it more)? There's a lot of information about the telescopes lenses and mirrors, but very little about the eyepieces... There's also something curious I found out on high power eyepieces: it seems that on a 4mm eyepiece you can see exactly the same "viewing area" as the 25mm eyepiece, still, since the hole of the eyepiece is so tiny, you can only see the center, the remaining image can only be viewed by "peeking" at an angle. that totally surprised me lol
  2. I no longer have that telescope, I gave it to a person that wanted it to make a roach killer canon
  3. My first view of Saturn is something I'll never forget, well, I'll never forget the blob with 0 detail I just saw on a 114mm telescope lol, a terrible experience you cant possible forget lol I knew amateur astronomy would be small, I just didnt knew it would be so fuzzy How do you guys even observe planets? The more you zoom on them, the faster they run off the screen.
  4. Instead of wasting more money on this one, I'm gonna try a long focal ratio refractor next, any recommendations?
  5. Got it decently collimated (secondary concentric and primary center matching the collimation cap hole). The views didnt improve anything, so, guess this is what it gives for real. Maybe collimation improves photography, but for seeing directly on the eyepiece, good enough and perfect are pretty much the same. Lesson learned. There are so many factors that allow for a great view that if you mange to meet them all at the same time, it's a celestial miracle, Amen...
  6. By zooming on a bright star and going out of focus, I cant see any circular pattern, all I see is the shadow of the secondary. The oddest thing is that shadow looks concentric at the center of the eyepiece field of view, but when I move it to the edge of the field of view, it's no longer concentric.
  7. Collimation cap? I've read that you cant collimate a f/4 telescope with a collimation cap. @Philp R: It's 1.25", no adapter needed.
  8. Hmm, let's see - I need a way to find if my telescope mirror is parabolic or not (is there a method that can be used?), telescope model is: Bresser Solarix 114/500 (I dont see that model on the list of "not to buy" telescopes, but you never know lol). - The default eyepieces that came with it were "K9mm" and "K25mm", I assume they're bad quality, but i can't tell for sure. I have a plossl 4mm that I bought separately, but I cant compare with the others since their focal ratios are so different. The 2x barlow that came with it feels very light and cheap, but does its thing. - I did some rough collimation check, most likely not spot on, need to get a cheshire and center spot the primary.
  9. Thanks for your bits, so, what I'm seeing is really what is supposed to be... Good to be informed...
  10. I've recently bought a 4.5 inch reflector telescope, so far, by looking at the eyepiece I didn't see anything special. The sun and the moon have detail (not a surprise since the first is gigantic and the second is so close), but for everything else, I didn't see anything special. Jupiter was a fuzzy ball, no detail at all. Saturn was even more fuzzy, Andromeda was a small smudge smaller than the moon, and the Pleiades were brighter than the other dots, but they were still nothing but regular dots, same as all the others. I have a simple question, on those internet topics that show what you can see with a small telescope, they're referring to the long exposure image you can get from a camera, not really what you can see directly on the eyepiece, right?
