About this product

Model:  hyperion_zoom
Part Number:  2454826

NEW smaller, lighter Baader Hyperion Mark IV Zoom.

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. 


  • Seven element, multi-coated optics for remarkable sharpness, contrast and colour correction.
  • Smooth zoom action with click-stops at 8, 12, 16, 20 and 24mm.
  • Parfocal across the entire zoom range.
  • Wide 68 degrees FOV at 8mm, 50 degrees at 24mm.
  • 12-15mm eye-relief and adjustable rubber eye-cup for comfortable viewing with or without spectacles.
  • Includes both 1.25” and 2" barrels - threaded for filters.
  • 'Zero Tilt Safety Kerfs' for a secure fit in the eyepiece holder.

Simple to use - good recommendation by FLO

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.

Baader Hyperion Zoom MkIV
Friday, 26 February 2021  | 

Great eyepiece with clear and focussed views across the full range. Feels particularly well made and expertly packaged and presented. My only issue is that I cannot feel the click stops no matter how slowly I adjust the zoom; not just me as my wife could not feel them either. Hence the 4 star review rather than 5.

Simply beautiful

First of all, I could not find anyone in the United States that had this in stock. Firstlight optics had it at my door in Chicago in a matter of a couple of days.
The item itself, has lived up to the ratings it has received. I donít have any complaints what so ever about this purchase.

Outstanding Eyepiece
Thursday, 26 November 2020  | 

Before you spend a lot of cash buying eyepieces, you should consider this eyepiece first. Its like having many eyepieces in one. This eyepiece produces very clear images at all ranges of magnifications and has good eye relief. I have been absolutely satisfied with my purchase. I live in California and none of the US retailers had this eyepiece in stock, but found it on FLO and ordered it. I was impressed when I received the item a few days later and in perfect shape. Thanks to Baader for a great eyepiece and to FLO for a great customer experience. (I also recommend purchasing the companion Baader Hyperion 2.25x Zoom Barlow for the zoom eyepiece as well.)

What can I say, looks and feels very good, have only done a quick test from the porch in day light to the hill (about a mile) on the other side could zoom in on birds sitting on fence posts with no problem, just need the skies to clear and give it a good test. Also got the barlow for this E.P. so will test that out on the same night.

My prime reason for the purchase of this hyperion zoom eyepiece was the flexibility. The eyepiece itself and the ease at which you can find what you are looking for and then zoom in for a closer view is superb. It enabled me some excellent views of Mars. By then adding an adapter, I was able to connect my DSLR to the eyepiece and take photographs. Build quality 100%, FLO service 100% value for money 100%. Well pleased.

Just to add, I ordered a couple of items at the same time, due to extended deliveries, FLO without asking for additional delivery payments, sent the items separately. Superb customer service. Thank you.

Excellent eyepiece
Saturday, 25 July 2020  | 

I purchased this not expecting much but it really is great. I use it more than most of my other eyepieces (luminous eyepieces). The convenience of having multiple eyepieces in one package is brilliant and worth the trade off for the FOV, I also find the clarity nice and crisp (just as good as my luminous EPís) but does start to tail off at 7mm Would highly recommend.

Very pleased with this so far. Only used it for solar viewing up till now in combination with a Lunt solar wedge and Baader polariser . Great for this activity as the 'seeing' can vary quite a bit in in a session and this then saves swapping eyepieces and polarising filter. Using it in a 100mm refractor. Am looking forward to testing it out on lunar viewing. I had a budget zoom before this and they are like night and day in quality of seeing. Very pleased with purchase. Excellent service as always from FLO also.
