Vaonis Vespera III Smart Telescope

50mm f/4.9 Apochromatic Quadruplet Optics

Vespera III's optical design is a significant leap forward, employing a four-element apochromatic lens structure. This quadruplet design, paired with a refined field corrector, delivers pinpoint stars across the entire 11.2 x 6.3 mm sensor, eliminating chromatic aberration and field curvature that can soften stars at the edge of the frame. The 245mm focal length produces a wide native field of view perfect for capturing large nebulae and entire star clusters.

8.3 MP Sony IMX585 with 24 MP CovalENS Mosaic

At the core of the Vespera III is a 1/1.2" Sony IMX585 color sensor, offering a native resolution of 3840 x 2160 pixels. The 2.9 µm pixels provide a fine image scale of 2.39 arcsec/pixel, balancing detail with sensitivity. For targets that exceed the native 2.5° x 1.4° field, CovalENS automated mosaic mode stitches multiple panels together, creating expansive 24 MP images with a maximum field of 4.33° x 2.43°.

11-Hour Battery and 115 GB Onboard Memory

Engineered for full-night autonomy, the Vespera III operates for up to 11 hours on its internal battery, removing the need for external power packs. Every image you capture, from single FITS files to pre-stacked TIFFs, is saved to the 115 GB of onboard storage. It also offers 15 multi-night slots, so a project can be resumed over several nights.

Integrated Hygrometer and Anti-Fog System

Dew is the enemy of all-night imaging, and the Vespera III actively combats it. An included hygrometer sensor continuously monitors ambient temperature and humidity. When conditions approach the dew point, the telescope's built-in anti-fog system automatically activates, keeping the optics clear and your images sharp from dusk until dawn.

Vespera III vs. Vespera II: Quadruplet Optics and All-Night Power

The Vespera III introduces critical upgrades over its predecessor, the Vespera II, primarily in optical design and operational endurance.

• Optical System: Both models use an apochromatic quadruplet; the Vespera III's is a new design with precision optical baffles that suppress stray light for more contrast.
• Battery Life: Endurance sees a major boost from around 4 hours in the Vespera II to 11 hours in the Vespera III, making true all-night sessions possible without external power.
• Storage: Internal storage has been expanded to 115 GB, a substantial increase that allows for more extensive image archiving directly on the device.
