Celestron's Mini Maks are designed for those who value both portability and adaptability. Known for their compact and user-friendly Maksutov optical system, these scopes are suitable for both land-based and celestial observation.
The C70 Mini Mak, a petite yet potent spotting scope, comes complete with a tabletop tripod featuring slow-motion controls. It also includes a built-in zoom eyepiece that can achieve up to 75x magnification and a soft case for easy transport.
About Maksutov-Cassegrain Optics
The Maksutov-Cassegrain, or MAK, is a catadioptric design that employs both lenses and mirrors. Light entering a MAK travels through a corrector lens, hits the primary mirror, bounces back to a spherical secondary mirror, and finally reaches the eyepiece. The resulting images are crisp, bright, and largely free from chromatic distortion.
Unique to the MAK design are a few key features. Rather than having a separate secondary mirror, the MAK utilizes a "secondary spot," which is a reflective coating applied directly on the interior surface of the corrector plate. This eliminates the need for frequent collimation adjustments. Additionally, the secondary spot's smaller size contributes to the MAK's distinctively high-contrast visuals.
However, it's worth noting that the Maksutov-Cassegrain design does come with a drawback: the more substantial Maksutov corrector plate takes longer to acclimate to the surrounding air temperature.

| Solar Warning |
- Never look directly at the Sun with the naked eye or with this optic. Permanent and irreversible eye damage may result.
- Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
- Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
