AT 1 0 2 E D  
Thank you for choosing this Astro-Tech AT102ED high-  
performance ED refractor.  
The images from its 709mm focal length f/6.95 ED (Extra-  
low Dispersion glass element) air-spaced doublet optics are  
virtually color-free, even at high magnifications.  
Its package of standard features – a dual-speed Crayford-  
style focuser, an illuminated multiple reticle finder, tube rings  
with a separate Vixen-style dovetail, hard case, and more –  
from Astronomy Technologies  
is unsurpassed at its sensible price. We believe you will  
agree that the performance and features of your AT102ED  
make it an exceptional value.  
This sheet will provide you with information on how to  
get the most out of your new scope, and how to maintain  
it so it can give you a lifetime of observing enjoyment.  
Please familiarize yourself with the parts and functions  
of your AT102ED before operating it for the first time.
