An aperture of 50mm is very small. Why this choice?

An aperture of 50mm is very small. Why this choice?

You'd be amazed what you can get with a 50mm apochromatic quadruplet! Just look at the results of the RedCat bezel, which alone (no frame, tripod or on-board computer) costs $750.
The most important thing to remember with Vespera :
- its speed of installation (3min)
- its ease of use (anyone can use it)
- its weight and size: it's really the most compact instrument in the world
- the speed with which you will get a first result (5min)
We challenge anyone to do better in less than 10min :)
