![]() ![]() The strikingly long tube is 35-inches long which might be offputting for some, due to storage and transportation reasons, but the length gives us a ratio of f/13 which significantly benefits optical performance when looking at the moon and nearby planets. We wouldn't necessarily say it is for beginners, as it does have some niggles which make it more difficult to use than other models, and doesn't give much room for growth. The Celestron AstroMaster 70AZ telescope is aimed at astronomers on a budget who want a fuss-free, toolless setup. Here are some of the best telescopes for seeing and capturing planets. This will allow you to observe in the sweet spot on most nights when the seeing is average. Astronomers should also consider Barlow lenses to help attain high magnifications of between 120-250x (within the optical limit of the telescope). Eyepieces with greater magnifications can help get larger views of the tiny planets. There are also other optical accessories to consider when shopping for a planet-hunting telescope. Refractors are bulky, heavy, and expensive, so compound telescopes such as Maksutov-Cassegrains and Schmidt-Cassegrains make for a good compromise. ![]() For many dedicated planetary observers, a large refractor is a dream, but there are downsides. When shopping on a budget, there's an argument to be made for choosing a smaller refracting telescope than a similarly priced but larger reflector, because the secondary mirrors and struts in Newtonian telescopes perturb the incoming light in a way that reduces image contrast. ![]()
