The Discovery Channel Store specializes in scientific optics, particularly for astronomy. They carry both astronomy binoculars and a range of reflecting telescopes and refracting telescopes. We are a little surprised that TDC Store doesn't carry any microscopes, particularly with the entry-level microscopes and high-quality models for children available.
However, if you are into astronomy you are in luck. The Discovery Channel Store stocks a thoughtfully chosen selection of telescopes and astronomy binoculars. They carry a couple of 8x and 10x magnification binoculars from Celestron and Orion that seem chosen as much for price points and brand as for features. However, both are quality and will serve well for the beginning astronomer. We hope to see their selection of astronomy binoculars grow in the future.
The telescope selection at TDC Store is very well thought through, and is their optical specialty. They carry reflector and refractor telescopes from Meade, Orion and Coronado. They also have mirror lens telescopes from Orion, Celestron and Nexstar and others. Their telescope selection is not extensive, but offers choices for astronomers at every level whether beginner, intermediate or advanced, and at multiple price points. We have not ordered from TDC store but given their focus on astronomy that their staff are well trained on pre-sales and support issues.
