One barrel across a range, with a field that narrows · review
An 8–24 mm zoom that fits both 1.25 in and 2 in focusers and carries an M43 camera thread, supplied with an extensive accessory set.
The bottom line A system eyepiece with two fittings and no published optics — bought on the name, not on the listing.
Telescope side: 1.25 in and 2 in. Camera side: M43. Accessories: extensive. That is the entire advertisement for the most expensive eyepiece on this shelf.
Seating directly in either barrel size means no adapter and no extra joint, and it means one eyepiece serves two telescopes. The M43 thread on the eye end puts it into a photographic system rather than leaving it a purely visual part.
Apparent field at either end of the range. Coating. Element count. Eye relief. Weight. Every figure that this page would normally publish for an eyepiece, in other words.
On the manufacturer’s own published data, found at the source, rather than on this listing. The fittings above are what the advertisement establishes, and they are genuinely the unusual part.

It is the camera-side fitting for this eyepiece family, and it allows a camera to be coupled for eyepiece-projection photography with the correct adapters. It is a system thread rather than a general astronomical one.
A 2 in focuser normally needs an adapter for a 1.25 in eyepiece, and the adapter adds a joint. An eyepiece that seats directly in either removes that, and keeps the same eyepiece usable across two telescopes.
