SUMMARY

The discussion centers on the challenges faced by a new telescope owner using the Celestron SkyProdigy 130. The user reports that planets appear as small dots, particularly Jupiter, and seeks advice on improving their viewing experience. Key recommendations include using a 2x Barlow lens to enhance magnification and adjusting expectations regarding the capabilities of a short focal length telescope. The conversation highlights that while the telescope is suitable for wide-field observations, it is not ideal for detailed planetary viewing due to its optical design.

PREREQUISITES
  • Understanding of telescope optics, specifically focal length and magnification.
  • Familiarity with eyepiece specifications, including eye relief and focal length.
  • Knowledge of Barlow lenses and their impact on magnification and brightness.
  • Basic awareness of celestial objects and their visibility conditions.
NEXT STEPS
  • Research the use of Barlow lenses, particularly 2x and 3x options, for enhancing planetary observations.
  • Explore different eyepiece options compatible with the Celestron SkyProdigy 130 to improve viewing experiences.
  • Investigate the effects of light pollution on astronomical observations and how to mitigate its impact.
  • Learn about telescope accessories, including filters and additional lenses, available from third-party retailers.
USEFUL FOR

Astronomy enthusiasts, beginner telescope users, and anyone interested in enhancing their planetary and deep-sky observation skills will benefit from this discussion.

My wife's co-worker looked up the Comet-Catcher on the Internet the night she gave it to him and he wanted to give it back because she didn't charge him enough money. When he got it home, his little girl hugged the tripod and wanted to go right out and use it when it got dark. He told her that she'd have to wait because he needed to order an eyepiece or two and she said "But Daddy, I hate to wait!" Good feelings! Her first telescope experience will be a decent one.

No WalMart 60mm/"500X" refractors for her. I bought that CC because I wanted something grab-and-go for deep-sky stuff even though we lived in a relatively light-polluted area. Her father grew up in a densely populated region of Indiana and never saw the night sky properly until he moved here to central Maine, so the 'scope will be just as fun for him as for his little girl.

The moral of the story: Hunt down some experienced amateur astronomers and indicate your willingness to buy a telescope. You might find that you get a hell of a deal, especially if the owner likes you and you have kid(s) involved. I didn't need the money, and putting a nice little 'scope on a lawn sale will get you nothing, so the nominal charge was just enough to make him feel OK about taking a 'scope and tripod initially, so his little girl could see some faint stuff from their driveway, and perhaps graduate to something better when he's got enough money saved up.
