The Zhumell Z12 is just about the biggest telescope we would recommend to beginners, and we would only recommend it to be your only telescope if you are strong and in good health, or if you can keep the scope on a dolly or hand truck to roll outside. Otherwise, you are going to end up missing out on clear nights due to the sheer bulkiness of the scope and you’ll need a smaller instrument to complement it. This being said, you simply can’t get more bang for your buck than the Zhumell Z12.The Z12 is more or less a scaled up version of the Z8 and Z10. If you are unwilling or unable to deal with the size and mass of the Z12, our comments here mostly apply to those two smaller scopes as well, and we love all of the Z series Dobsonians equally. If the Zhumells are not available in your region, the Orion SkyLine, Apertura AD, GSO Deluxe and Bintel Dobsonians are all pretty much the same both in design and accessories.
