Dobsonians give you the most aperture for your money, are extremely simple to assemble and aim, and are lighter and more compact than most telescopes of comparable aperture using other optical/mount configurations. For most beginners, an 8”
Dobsonian telescope offers the most value for your money, though smaller 4
tabletop scopes are also superb, and some may opt for a larger 12”
. Tabletop Dobsonians in the 4-6” aperture range are ideal for those who are tight on budget or storage space, while also making a superb complement to a larger telescope on those nights when you don’t feel like setting up the bigger one. Some people may even have three Dobsonians or a combination of multiple telescopes to fulfill their requirements. Equipped with tracking, Dobsonians are also superb planetary imaging telescopes. However, they are not usable for long-exposure deep-sky astrophotography.
