Common Questions Asked About Small Telescopes

What makes a small telescope “high-performance”?
While compact in size, our small telescopes use high-end optics and coatings to ensure sharp resolution, low distortion, and thermal stability in varying conditions.

Are these telescopes suitable for space or satellite use?
Yes. Our lightweight, athermal designs and mirror materials like SiC make them ideal for small satellite payloads and orbital imaging.

Can I integrate these with my imaging sensor or custom mount?
Absolutely. We offer flexible interface options and will match your sensor specifications during the design phase.

Do you offer off-the-shelf options?
We provide baseline designs for quick turnaround but also specialize in fully customized builds to meet your mission requirements.
