I have a Celestron Regal M2 80 mm spotting scope and was interested in buying some fixed focal length eyepieces to add to my original Celestron zoom eyepiece.
I read on the Baader-Planetarium.com website that some spotting scopes have difficulty getting infinity focus with your Baader Hyperion eyepieces and therefore, with your 8-24 mm zoom eyepiece, additional (spacer ) rings are provided to achieve this.
The website specifically refers to Celestron Ultima spotting scopes. Do you know if this is also the same with Celestron Regal scopes or not?
If it is, can these rings [a] be purchased and [b] will they fit on your other Baader Hyperion eyepieces?
I was specifically interested in the Baader Hyperion 68 degrees 8 mm and the Baader 31/36 mm Hyperion Aspheric eyepieces.
Astronomical eyepieces have to come close to a spotting scope. The Hyperion Zoom Mark IV is designed to be compact enough, so these rings shorten the body of the eyepiece. Unfortunately, they only fit onto the Hyperion Zoom Mark IV.
The Hyperion Aspheric (31 and 36mm) will not work with any spotting scope as their 1.25"-adapter is too long. The 8mm will work without any problems (as well as all HYperions except the 5mm and the discontinued 3.5mm), but it provides the same magnification as the original eyepiece from Celestron. The 5mm will probably not work, at least it doesn't work with the Zeiss Diascope spotting scopes.
On the other hand, all our newer eyepiece lines (the Morpheus and the Classic Ortho/Plössl) will work with your spotting scope out of the box.
