If Vespera is smaller than Stellina, do I lose quality?

If Vespera is smaller than Stellina, do I lose quality?

Vespera's aperture and resolution are indeed smaller than Stellina's but you'd be amazed to see what you can get with a 50mm apochromatic quadruplet! Just have a look at the results of the RedCat refractor, whose refractor alone (no frame, tripod, or onboard computer) costs $750.
You can find a sample of pictures taken by Vespera:

The Moon
M31 - Andromeda Galaxy
M27 - Dumbbell Nebula
