It seems that the guys here have been writing quite a bit lately about the Swarovski ATX/STX spotting scope using the 85mm objective. As they compare this with other 80mm class scopes, it performs so well that it makes sense to me they have had it in the field this much. The performance of the 85mm objective is really impressive but the scope also offers the advantage of simply switching out the objective to either a 65mm or 95mm objective for different conditions or preferences. What this means is that by simply changing the objective you have a completely new scope!
When Swarovski first announced their new design that allowed switching objectives to different sizes I’ll have to admit that I was a bit skeptical. All the same, the different sizes offered interesting possibilities and some really impressive capabilities. Since the guys have written a bit about the 85mm objective in other posts here and have shown some impressive results with both point and shoot and micro 4/3rds cameras I thought I would test the other modules using my Canon 7D DSLR camera. As a note before I discuss these other two modules, at this time there is no other scope on the market that has digiscoping adapters that are as simple and complete. This means that you can easily take a photo of what you are looking at through your scope with any of the aforementioned camera types. I won’t go into detail about that here as it is discussed in detail in the scope review.
When Swarovski originally brought in their new ATX/STX spotting scope to show us, they brought the 65mm objective and eyepiece module in a binocular field bag! This combination is extremely compact and opens the possibilities of traveling with a spotting scope like never before. I took the photo at the left with the 65mm module. The intent of this picture was twofold. First is brightness, color, and sharpness. I’ll let the image speak for itself and just say that if I can get this photo through the scope with a camera, what you see looking through the eyepiece is really bright and sharp. Second is closeness. The Swarovski ATX/STX spotting scope with the 65mm objective will close focus to 6.9 feet! That is closer than most binoculars. This means that the whole world of small is now possible at up to 60 times magnification. I could go on about this little scope but with the same camera I figured I’d see what the 95mm objective was capable of.
Most of us know that the more light you let in through the objective end of a scope the more potential clarity, resolution, color and contrast you can get out the eyepiece to see stuff. The problem in the past has often been size limitations of what was reasonable to carry in the field. The balance was to have objectives in the 80mm range so you weren’t trying to carry around a big astronomical telescope (not mentioning the inverted image) that had a large objective to let in lots of light so you could get great detail even in poor lighting conditions. A larger objective opens a world of distant viewing in tough lighting conditions. My poor man’s test of this was to walk out in front of our store after work at night, in the bright street lights (light pollution), and take a picture with the 95mm objective.
The picture at the right is my attempt of low light, distant viewing. The ATX/STX scope with the 95mm objective, having a zoom range of 30-70x, also opens a possibility of zooming out at greater distances (most scope zoom ranges are 20-60x) and still seeing sharp images. The photo above was shot at about 7 feet away and in this photo my subject is about 240,000 miles away. So my quick test here might be more appropriately titled “Big or Small, Day or Night, Really Close or Way the Heck Out There”. If versatility and top performance are the deciding factors, then this scope is really hard to beat.
