For sale is a Baader Hyperion Aspheric 31mm in excellent condition. AFOV is 72° and weight is only 400g.
Edge performance isn't as good as more complex eyepieces like Tele Vue but the Baader is substantially lighter and cheaper. Where this eyepiece shines is in contrast/transmission (similar to the Masuyama 85° EP's).
Selling as I also have the 36mm and don't need both.
Comes with original box and standard accessories:
- 1.25" adapter
- Winged eyeguard (can swap with eyeguard fitted in pics)
- Caps
- Leatherette pouch
Asking $150 or trade involving items listed below:
- Takahashi LE 18mm (green lettering)
- Celestron Ultima 18mm (original version, not Ultima Edge)
- Tele Vue Plossl 17mm
- Baader Moon & Skyglow filter 1.25"
- Baader UHC-S filter 1.25"
Enquiries by PM please.
