- 35x with 95mm Models
- 30x with 65mm/85mm Models
Fully compatible with all versions of their ATX and STX spotting scope systems, Swarovski Optik's BTX 30x/35x Eyepiece Module represents the pinnacle of comfort for long-duration glassing sessions. The innovative design replaces the conventional single eyepiece with a dual-eyepiece binocular configuration that enables users to view with both eyes open, and with the eyepieces set at a 45° angle to the optical tube, their head is put in a natural viewing position. When mounted on the 65mm and 85mm models it has a 30x magnification, whereas the 95mm version is stepped up to 35x. Both models have a 63° wide apparent angle of view. To match the performance of the objective modules, this eyepiece module has the SWAROVISION system to improve color fidelity, contrast, and clarity; and SWAROCLEAN coatings help keep the lenses clear and easy to clean.

Is the optical quality superior to my current 30X70 zoom? I assume so since zooms usually are inferior. Tests? Proof of image quality over zoom? If used at night for astronomy, e.g., estimating magnitudes of variable stars, will the small 2.7 exit pupil be a negative to the point "not really usable at night sky"? What about splitting the light into the two barrels? Will this also be an issue of "not really meant for nighttime sky viewing"?
I own both the angled 30x70 zoom lens and the binocular BTX 35x eyepieces for my 90mm Swarovski modular spotting scope. Two me they are two different tools in the tool box. The 30x70 zoom eyepiece is ideal for scoping distant birds for bird watchers (which I am), especially for distant waterfowl on a lake as you pan the 180 degree vista in front of you. This combo is also ideal for watching shorebirds. You find the ducks at 30x and if you can’t identify them, you use the zoom feature. I use the binocular eyepiece for nest watching only these days, such as Bald Eagle and Osprey nests, or Purple Martin houses. With the binocular eyepiece, the whole unit is kind of heavy and bulky so you do not want to be lugging it too far in the field. I find the depth of field and, therefore, the focus, very sensitive with the binocular eyepiece. The binocular eyepiece is not the best choice if you are sharing the scope viewing experience with others because they will have to adjust the interpupilary distance of the two lenses and possibly the adjustable rings that aid in the distance your eyes are from the lenses. Optically, both lenses are mind-blowing! I have used the binocular eyepiece at night watching birds and bats fly silhouetted in front of the full moon. It was extremely sharp and bright. I am in my late 60s and have owned and used just about every make of scope. I am an Ornithologist so watch birds for a living, for citizen science, and for pleasure, and nothing can touch the quality of this scope for bird watching. I am sorry, for astronomical endeavors, I just don’t have the experience or expertise to answer your questions.
