What is the main advantage of the Amici prism in the Baader 45° Diagonal?
The primary advantage is a fully corrected image. An Amici prism corrects the view both vertically (up-down) and horizontally (left-right). This provides an intuitive, non-reversed image identical to what you'd see with your naked eye or through binoculars, which is essential for terrestrial and daytime observing.
How does the Baader 45° Amici Diagonal work for birdwatching with a Celestron 8" SCT?
It's an excellent combination. The diagonal threads directly onto the 8" SCT's rear cell for a stable connection. The 45° angle is comfortable for scanning landscapes or treetops, and the correctly oriented image makes it easy to follow moving birds. Using a low-power 2" eyepiece gives you a wide field to locate subjects, while a higher-power 1.25" eyepiece lets you zoom in on details.
Can I use the Baader 45° Amici Diagonal to view the Moon?
Yes, absolutely. It's a great choice for casual lunar viewing, as the Moon will appear in its correct orientation, just as it does in the sky. For high-magnification scientific observation of subtle crater details, a high-quality 90° mirror diagonal may provide slightly better contrast, but for an intuitive view, the 45° Amici is perfect.
Will this Baader diagonal work with my refractor or Newtonian telescope?
No, this model is designed specifically to attach to the 2" SCT thread found on the back of Schmidt-Cassegrain and some Maksutov-Cassegrain telescopes. It does not have a standard 2" nosepiece to slide into a refractor's focuser drawtube and is not intended for use with Newtonian reflectors.
Why is a 45° diagonal better for daytime use than a 90° diagonal?
The 45° angle provides a more natural and comfortable viewing position when your telescope is pointed horizontally or slightly downwards at terrestrial targets. A 90° diagonal would force you to look straight down into the eyepiece, which is awkward for daytime use but ideal for looking up at astronomical objects near the zenith.
Does this Baader diagonal accept both 2" and 1.25" eyepieces?
Yes. The Baader 45° Amici Prism Diagonal has a native 2" eyepiece holder and comes with a 2" to 1.25" reducing adapter. This allows you to use the widest possible range of eyepieces, from low-power 2" wide-fields to high-power 1.25" planetary eyepieces.
