Great glass? With it, you cannot only get a clear image of the planets and the Moon, but also of Milky Way star clusters and nebulae. It is light weight and portable so you can view and photograph anywhere. You’ll quickly find that refractor telescopes come at all different price points. There is an objective lens that refracts light, hence the name, and the long tube allows light rays to come to a focal point and focal plane so that an image can be seen with use of an eyepiece. ExploraScope 70AZ Telescope. See the below engineering drawing. Speaking of aberrations, the CA isn’t bad with this scope due to its much longer focal ratio of f/11. This guide section covers Refractor Telescopes 101. APOs are coveted for astro-imaging because of the quality imaging benefits they provide. Even with the light-duty setup, you can get away with unguided, short exposure images of the moon and planets. While achromatic doublets do help to minimize CA, don’t expect to see it completely eliminated. Your eyepieces are the first accessories you should learn to use with your telescope. If you’re after the larger size that a Newtonian offers on a GEM mount without CA getting in the way, the Omni XLT 150 is a great option to consider. If you are searching for an innovative telescope, then the Celestron Omni XLT 150 Refractor Telescope can be a great option. Celestron Solar Safe filter technology is GUARANTEED SAFE for direct solar observation and has been independently tested by SAI Global Assurance Services. This is quite large for a refractor, and it has good optical quality. With premium features, it makes it easy for you to observe the night sky right out of the box, without the need to use other accessories. Views will be better than average thanks to the optical doublet. Obviously, the more elements there are, the heavier the optical assembly becomes which affects overall weight of the tube. Why do you need the extra power? Medium-speed scopes are good for seeking out planets and DSOs, and this model will provide satisfactory views of both types of objects with some compromise. Switching between the two saddle plates is as simple as moving the hand knobs into a separate set of holes. Download the Celestron PWI Telescope Control Software. The tube is made with carbon fiber, so it shaves off a small amount of weight, but it’s primary benefit will come from its excellent tube stability during temperature changes. Fast speed, good wide fields of view on DSOs, and a large aperture to top things off. Glad you asked. Better quality can equal better visibility and tracking accuracy. The ETX 80 Observer is an achromat doublet, so you’ll see come CA minimization benefits at work, although it won’t be completely eliminated. It has an achromatic doublet with ED glass which provides its APO-like benefits to minimize CA, improve contrast, and maintain resolution. You will learn the basic workings of a refractor and why they can be so expensive. With an EQ mount, you can try some unguided, short-exposure photos with a planetary camera, but a DSLR and guiding equipment will require a motor and heavy-duty mount/tripod system. The aperture is 80 mm, so it’s on the small side, but it provides a good balance between portability and ease of use. Today, our world-class team of optical and electronic engineers continues to push the boundaries of technology. To snap photos, a built-in smartphone adapter is included. They’re typically what we think of when telescopes come to mind. Without further ado, let’s “refract and bend” these telescopes to reveal every little detail about them. For more information on CPWI and to see the user interface, click here. Losmandy plates are a millimeter or so wider, but CGE plates allow more surface area contact with the dovetail clamp. Planetarium software package which provides easy-to-understand explanations and impressive visuals of all kinds. The price is only a downside if you don’t have the cash to fork out, but it’s not bad at all considering it comes with the all the fixings from the mount to accessories and a hard case. I have a Losmandy D format dovetail plate, but it is not manufactured by Losmandy. But, what is the Omni good for? Your eyepieces are the first accessories you should learn to use with your telescope. 6. Just point the telescope at any three bright objects—stars, bright planets, or even the Moon—and your telescope can orient itself with the night sky. The NexStar+ hand control gives you instant access to all the functions your mount has to offer. If you can identify key features and acquire an understanding of the focal specs of a refractor, you’ll be able to confidently pull the trigger on the best type of refracting telescope to achieve your astronomy goals.
