This 4th generation Baader Hyperion 8-24mm Click-stop Zoom is smaller (55mm wide) and lighter (290 grams) than its predecessor (the Mk-III model was 80 grams heavier). This makes it an especially good choice for use with binoviewers.
The click-stop mechanism has been improved - it has the usual 8, 12, 16, 20 and 24 mm indentations but the mechanism is softer and more reliable in very cold conditions.
It has an additional four millimeter 'back-focus' so is more compatible with spotting scopes that accept 1.25" eyepieces. The longer back-focus, together with Baader's type A adapter ring, means it is more likely to achieve focus at infinity when used with a spotting scope and, when the 1.25 "nose-piece is removed, a 1 3/8" thread is revealed that enables the eyepiece to be screwed directly to Celestron Ultima spotters. A bayonet adapter is also available that enables the eyepiece to be used with Zeiss Diascope spotters.
The optical quality and specification is unchanged - it has the same wide 68 degrees FOV at 8mm and 50 degrees at 24mm and features Baader's 'Phantom Group' multi-coating on all air-to-glass surfaces.
It also remains fully compatible with the Baader 2.25 x Hyperion Barlow (sold separately).
As with previous Baader Hyperion Zoom eyepieces, the Mark IV model features a M43 thread for easy connection to a DSLR or T2 accessory via an optional M43 / T2 adapter.
The eyepiece is supplied with 1.25 and 2" nose-pieces that feature Baader's patented 'Zero Tilt Safety Kerfs' for added peace of mind (less likely to fall out of the eyepiece holder). A yellow storage pouch is also included.

I spent much time researching a zoom lens, deciding on this. It does not disappoint.

First use of this with our StellaLyra 8” Dob, treated as 1.25” lens and no problems focusing added Barlow again no issues with focus. Just what me and my daughter needed, zoom out find thing, then zoom in - Orion Nebula Trapezium which for a couple of new scope users was really good to see. Happy 60th to me!

After a great deal of deliberation I eventually decided to find out if one eyepiece really would meet most of my needs - It does!
I think it's biggest benefit is that it leaves me free to focus (sorry!) on what I have set the scope up to see and not on ferreting about in the dark for other eyepieces - I should have bought one ages ago.
The quality of the optics is superb and having compared it against several other (single focus) eyepieces I can confidently say that you really do get 5 excellent eyepieces in one package. I bought the matching Baader 2.25x Barlow to go with the Zoom and would recommend that you do the same - they are a perfect pairing.
The delivery from First Light Optics was immediate and first class.

So glad that i finally caught these being in stock as they sell like hot cakes. The Zoom mechanism is silky smooth with just the right amount of click at the predetermined focal lengths. The image is clear and concise out to the edges, with plenty of contrast. All in all it’s a pleasure to use with just a small focus adjustment needed when changing the focal length
Wish I got one years ago!

Having gone through quite a lot of different EP’s over the years I finally got this Baader Hyperion Zoom EP and love it. Used mainly in my scopes now when viewing, this covers most magnifications I generally need and use, so not often is another EP used apart from this. Great delivery from FLO, and well recommended.

I couldn't make my mind up wether to buy this zoom or not, finally took the plunge and have to say I am really impressed with it's performance, the views of the moon last night were pin sharp and using the matching barlow images stayed crystal clear, click stops worked without fault, very happy with this zoom, thanks to Flo for as usual fast delivery service.

First up, great service by FLO, thank you again.
As a beginner to astronomy, wanted a zoom eyepiece for flexibility yet wanted a quality solution i could stick with for years.
Believe this is a great fit and a good recommendation by the team at FLO.
Still waiting for a really clear night to go beyond filling the view with Mars / Gt Orion Nebula.
