I have up for sale 2 Baader Hyperion 68 deg FOV eyepieces. I'm almost exclusively doing astrophotography these days and they need a new home where they can be used. It is pretty easy to get details on the eyepieces from the web and reviews are quite positive (4 or 5 stars).
Baader Planetarium Hyperion 5mm with 68 deg FOV model #2454605 $120 (retail $209.95)
Baader Planetarium Hyperion 21mm with 68 deg FOV model #2454621 $120 (retail $209.95)
They come with covers, leatherette storage pouches and original boxes.
In addition I have available an eyepiece projection adapter so you can attach a camera to the end of the eyepiece where you look into it:
Baader Planetarium Hyperion T-Adapter M43/T-2 model #2958080 (yes M43 to M42) $10 (retail $29)
There are an insane number of multiple configurations with these eyepieces.
* The eyepieces work with both 1.25" and 2" focusers
* The lower portion of the eyepiece (with the 1.25" barrel) is like a barlow and can be removed to get an eyepiece of longer focal length (less magnification) with an exposed female M48 thread to take 2" filters
* Or you can use M48 extension rings (not supplied) between the top and barlow section to shorten the focal length (more magnification)
* Under the rubber eye ring is a M43 thread (not a typo) and using the M43/T-2 adapter #2958080 you can do eyepiece projection
* Under the central rubber grip there is yet another larger thread to do something or other
* To further their versatility, they can be used as a door stop, paper weight, or thrown at neighbourhood cats
If you want all 3 items (2 eyepieces and T-adapter) then $190 (instead of $250). Tracked post shipping included with prices (except the T-Adapter unless bundled with at least one eyepiece).
