SUMMARY

The forum discussion centers on troubleshooting issues with a new telescope, specifically regarding collimation and the visibility of spider vanes. User Casey struggles to achieve a clear view of Jupiter, experiencing fuzzy images and diffraction spikes. Warren provides detailed guidance on collimation techniques, including adjusting the primary and secondary mirrors and ensuring the spider vanes are correctly aligned. Ultimately, Casey plans to contact Orion for a replacement secondary mirror assembly to resolve the ongoing issues.

PREREQUISITES
  • Understanding of telescope components, including primary and secondary mirrors
  • Familiarity with collimation techniques for Newtonian telescopes
  • Basic knowledge of eyepiece magnification and focusing
  • Experience with optical alignment and diffraction phenomena
NEXT STEPS
  • Research "Newtonian telescope collimation techniques" for effective alignment methods
  • Explore "how to identify and fix diffraction spikes" in telescope optics
  • Learn about "eyepiece selection and compatibility" with different focusers
  • Investigate "common issues with Crayford focusers" and their installation
USEFUL FOR

Astronomy enthusiasts, telescope owners, and anyone involved in the setup and maintenance of Newtonian telescopes will benefit from this discussion.

That would be "the" Telrad. There's only one to my knowledge. Just make sure that you get a type that has a bullseye of concentric rings, rather than a dot in the middle.

I am pretty sure that is what it is (not a dot).
Here's the pic.

Yep, that's a Telrad pattern. The rings are 1, 2, and 4 degrees wide, and can be used as a reference against your star charts. You may quickly begin thinking of the sky in terms of Telrad-ring-widths, and it'll be downright easy to gauge angular distances after a while.
