![]() Due to the nature of the ad-hoc plastic bracket, the included finder can be difficult to actually align with the telescope, making aiming the 70AZ (or indeed, any AstroMaster telescope) rather frustrating, if not nearly impossible. These are actually a retrofit, as the telescopes originally included very low quality plastic sights that were eventually removed. Therefore, a 25mm or 32mm eyepiece would be better.įor a finder, the AstroMaster telescopes have a decent quality red-dot finder with a really low-quality plastic bracket attached. However, 45x is a little much for low power with a 70mm telescope. ![]() The AstroMaster 70 comes with two surprisingly decent Kellner eyepieces – 20mm and 10mm – giving 45x and 90x magnification, respectively. ![]() However, a proper diagonal would cost nearly half the price of the telescope, and Celestron does bill this scope for terrestrial viewing, so it’s acceptable. The Amici prism produces a bright spike on bright stars and planets and isn’t very high quality. If you’re wondering about the odd shape of the diagonal and the strange grip that seems to be built in, it’s because Celestron has figured out that people tend to grab the diagonal and use it as a handle, and they designed it accordingly to be a little more suitable for that function. The Celestron AstroMaster 70 comes with a cheap, mostly plastic Amici diagonal designed to be used for terrestrial viewing. The Vixen-style dovetail plate which attaches to the mount is far too short to slide it for balancing, and the scope has no tube rings – the dovetail is directly attached via some screws in the tube. Like most of the AstroMaster scopes, the 70AZ can’t be balanced if you have anything remotely heavy on the focuser. The red-dot finder is attached to the left side of the focuser and is more than adequate for a small scope such as a 70mm refractor. The AstroMaster 70 has a 1.25” rack and pinion focuser, which is mostly plastic. The scope has an ample length dew shield, which also serves as a light shield to boost contrast, though it isn’t really painted a good flat black on the inside. The long focal ratio means that there is little in the way of chromatic aberration (false color), although not the near-zero that a 60mm f/15 refractor provides. Whether you are just beginning or an advanced observer, you will find yourself viewing the Moon again and again have the Observer's Map of the Moon be your guide.The Celestron AstroMaster 70 is a 70mm f/12 achromatic refractor using a standard Fraunhofer configuration with a crown and flint glasses for the objective lens. It makes a great display for your classroom or astronomy club. When not in use, the Moon map will be a stylish decorative poster on your wall. The Observer's Map of the Moon is waterproof, tear-resistant, and can be folded into an 8” x 4” size, making it easy to take along on your next camping trip, star party, or evening in your backyard. Refer to the lunar observing tips for practical information about using your telescope or binoculars to explore the Moon. You’ll also find images of the North and South polar regions for reference. On the reverse side of the map, there are close-up photos and information about the most exciting lunar regions to explore. You can observe features with your telescope and locate them on the map or vice versa. This map also features a directory of all the key lunar regions with coordinates to find them. Whether you are looking for Lacus, Maria, Montes, or Valles, the Moon map will help you navigate the lunar landscape with confidence. This quality map provides you a great way to familiarize yourself with the Moon, our neighboring world. Celestron has joined forces with master lunar cartographer Ralph Aeschliman on a two-sided Moon Map.
