The Vespera telescope is the latest offering from Vaonis, a French start-up. The company launched the Vespera (a mini version of its Stellina telescope launched in 2018) in October on Kickstarter. It is a hybrid between a smart telescope and a camera that is priced at a $999US (the Stellina is priced at $3,999US).
The Vespera utilizes a 1/2.9-sized IMX462 Sony CMOS sensor that is optimized for low light performance. The company has developed a proprietary digital card to correct warmth optimization and dissipation to maximize efficiency.
The Vespera offers users a simple interface by simply setting up the tripod using the adjustable legs and pressing a button. The Vespera uses a combination of its app and location services of a smart device to make recommendations for available astronomy targets. The app has a catalog of over 500 objects and will help you find, observe, and image those targets based on your location while also compensating for the rotation of the earth automatically. The user simple selects an object to observe and Vespera will point it out and follow it on the smart device.
