Small scope for astronomy

Can the   be used for light astronomy like the moon or stars?




Hi Casey,
Thanks so much for your inquiry.
You could certainly use the scope for light astronomy and to view the moon and larger planets. It wouldn't be satisfactory for viewing stars or objects in deep space.

If you have any further questions, please let me know.

All the best,

STM and STS Swarovski scope differences

Regarding the Swarovski 80 mm STS HD Spotting Scope: what is the  difference between the STS and the STM  scopes?

Thank you!


Hi Delphi,
Thanks so much for your inquiry.
The now discontinued STM and ATM bodies were made of magnesium. The current ATS and STS scope bodies are made of aluminum. The color of the focus wheel on the ATM/STM is green; they changed that to black in the newer ATS/STS models.

If you have any further questions, please let me know!

All the best,

Does the Swarovski ATX have HD lenses?

Do all ATX or STX Swarovski spotting scopes have HD lenses? They do not say HD on them that I can see like my HD ATS 80.




Hi Lindsay,
Thanks for your inquiry. The term HD (High Definition) is a marketing term rather than a technical term referring to a specific type of glass.   All the ATX and  STX scopes use Swarovski's Swarovision optical system which is noticeably improved over the optics in the ATS/STS HD scopes.  

Anyone using one of the new ATX/STX scopes would certainly say that they are "high definition" and regarding performance, one could safely say there is nothing better currently being made by any manufacturer.

If you have any other questions or I can help out any further, just let me know.

Best regards,

Is there a compact binocular for eyeglass wearers?

Hi there,

Looking for a 10x compact to stuff in my waist pack. I use a 7x42 and would use the 10x25 only when needed for more reach just on static birds (not moving) like perched raptor or duck on water in the distance. I know I can't follow moving birds with a compact. I wear glasses and the  looks the best for eye glasses.

But I'm worried about the tiny exit pupil and folding barrels. How frustrating is it to align with glasses or is it a bit easier than the other compacts? No IPD lock I would assume? Do the barrels get knocked out of IPD easily since both move independently?  Wondering if I shouldn't bother at all since compacts can be frustrating with glasses.

Thanks in advance,


Dear Beth,
Thanks for your inquiry! I understand your hesitation to try a compact as an eyeglass wearer--especially a 10x.

Having said that, I think the Swarovski is the one of the best compacts on the market for brightness, resolution, and ergonomics. It has more than adequate eye relief for eyeglass wearers. The hinge has good tension so barrels will, for the most part, hold their place while in hand. I don't know of any binocular that has a built-in IPD lock, but there is the Vortex Binoc-Loc for Roof Prism BinocularsHowever, that would make your compact binocular not quite as compact while stored in your waist pack.

You will have a significantly smaller exit pupil than what you're used to with your 7x42! Probably the best way to find out if you like it is simply order it. We ship fast and free (Fed Ex Ground) and you will have 30 days to field-test it.

If you have further questions, don't hesitate to write or call.

All the best,
