You get what you pay for, and I got these cheap binos to keep under my motorcycle seat. I should have got 8x25 not 8x21 as the brightness is not good. Optics otherwise average.
This is a fantastic product for EAA. With the variable weather here in Thailand, I am still able to get out under the stars for even a few minutes and get some great pictures, particularly of nebula and galaxies. I highly recommend the Seestar S50 for beginners and advanced astronomers (or wannabees).
