Frequently asked questions

How is this different from the FCD100 102mm?
Both are 102mm f/7 triplet apos; the FCD100 version uses higher-grade HOYA FCD100 glass for the best correction, while this Essential ED delivers excellent apo performance at a lower price.

Is a mount included?
No — this is the optical tube only. Use a sturdy equatorial mount for imaging or a capable alt-az for visual.

Good for astrophotography?
Yes — paired with a matched field flattener it's an excellent wide-field imaging scope.
