Pretty OK for a mass-mirrored scope (after having star-tested one, I'd wager to guess the mirrors are 'plain' GSOs), and certainly not undermounted. Bresser does fleece you a bit more than Skywatcher for the accessories (it's an EQ5-class mount but there are less third-party add-ons).
Not a "premium" scope with premium optics, of course, but it's refreshing to find a 130mm scope that isn't woefully undermounted -- you'll search for Synta kits with a 130/650 on an EQ5 mount (or even EQ3) in vain. Skywatcher forces you to buy the OTA and mounts separately, which increases the price.
