But for the planetary and Moon, it is more than enough. It is very limited though, what you can do regarding astrophotography, so don’t expect to make some cutting edge deep sky images. You can even make some videos or images of the planets and Moon with these telescopes. To switch between the visual and photo port, you have to use a small knob on the side that is used to rotate the erecting mirror inside the telescope. T-adapters are different for each camera manufacturer. Here you can attach any 35mm camera with the T-adapter. The neat feature here is a photo port at the end of the telescope. You focus the ETX 60AT and 70AT by rotating the front of the optical tube, something like with the camera lens to achieve focus. The standard telescope has focus knobs under the focuser where you put the eyepieces. This type of telescope has a unique focusing mechanism. Using the Barlow lens with eyepieces will give you more magnification if you need it. You can double or triple the focal length of the optical tube with the optional Barlow lens that you can buy separately. Divide the focal length of the optical tube with a focal length of the eyepiece, and you will get the magnification. The focal length of these telescopes is 350mm. These eyepieces will give you 14x magnification with 25mm eyepiece and 38x magnification with 9mm eyepiece. With the scope, you will also get two modified achromatic eyepieces, one with 25mm focal length and one with 9mm focal length. They are small, and another limiting factor is the atmosphere condition. It is just theoretical, and in reality, I suggest not to go over 110x magnification whit these telescopes.
MEADE AUTOSTAR ETX 70 MANUAL
The manual says that the maximum practical magnification for these scopes are 200x for 60AT and 240x for 70AT. MagnificationĬompared with the binoculars again, the magnification with the ETX is higher and adjustable with different eyepieces and Barlow lens. However, using it in the manual mode requires some knowledge of the night sky. Anyway, the batteries will last long, and you don’t have to panic if you forgot to bring some extra ones because these telescopes can also be used in the manual mode. If you are going on a long trip with this telescope, don’t forget to bring extra batteries to power the mount. The battery holder is conveniently hidden in the computerized mount battery compartment under the optical tube. It is pretty small, and you can even find binoculars with a bigger aperture, but you don’t have the stability and computerized mount option with binoculars. The numbers 60 and 70 means that the diameter (aperture) of the lens at the front is 60 or 70mm. Refracting telescope is using lenses to produce the image compared to reflecting telescope that uses mirrors. The Meade ETX 60AT and 70AT optical design is achromat refractor. Meade ETX 60AT and 70AT Telescope Features That’s why we call them “backpack observatory”. You won’t find any other computerized telescopes in this price range. So despite the small size, they will show you much more under the dark skies than bigger telescope near the city.Īnother great feature is that Meade ETX 60AT and 70AT are equipped with computerized mount and hand controller, so you don’t need to know the position of the objects on the night sky. It is a huge advantage over the bigger telescopes because you can easily take them on the camping trip or hiking trip under the dark skies, even without the car.
MEADE AUTOSTAR ETX 70 PORTABLE
These telescopes are made for use on flat surfaces like table tops, which is great because they are small and portable without the tripod. They don’t come with a tripod, but you can find some with it. These are not like other telescopes with the tripod. Which means you can have a portable observatory that can fit in your backpack for $50. Even though Meade doesn’t sell them anymore, you can always find them in the pawn shops or online marketplace for used telescopes. The Mease ETX-60AT and 70AT were very popular telescopes.
