We found it easy to assemble and disassemble without any fuss, opening it up to beginners with the budget and patience to dive in at the deep end, or anyone who is looking for, in our opinion, the best telescope on the market overall.It’s worth noting that it runs on 8x AA batteries, which can get pretty pricey pretty quickly if you have to keep repurchasing them — we’d recommend picking up some rechargeable AA batteries with a charger in the Prime Day deals to save you money in the long run.
