Reflector or refractor? Decide on your needs and budget. Refractors are usually more expensive but require less maintenance. Reflecting telescopes are popular because they’re cheaper and ideal for beginners. Do astronomers use reflecting or refracting telescopes? The autoguiding telescope I am using is a new StarField 50mm F/3.4 model, from Ontario Telescope and Accessories. This has replaced my old Altair guide scope but continues to house the reliable and no-nonsense Altair GPCAM2 AR0130 mono guide camera.

Celestron's EdgeHD technology greatly improves Schmidt-Cassegrain telescopes, especially for astrophotography. Normally, these telescopes create a curved focal plane that doesn't match the flat surface of a CCD camera sensor. This mismatch causes field curvature, making stars at the image edges blurry. However, Celestron's EdgeHD technology fixes this problem by providing a perfectly flat field. This means astrophotographers can now capture stunning, clear, and precise photos across the entire frame. The Astro Fi 6 inch is the largest computerized alt-azimuth Schmidt Cassegrain telescope in the range, perfect for terrestrial and celestial viewing on the go. The Astro Fi offers dazzling views of craters on the Moon, the rings of Saturn, the Great Red Spot on Jupiter, the Orion Nebula, the Hercules Globular Cluster and so much more at night. To guarantee you're getting honest, up-to-date recommendations on the best telescopes to buy here at Space.com we make sure to put every telescope through a rigorous review to fully test each instrument. Each telescope is reviewed based on numerous aspects, from its construction and design, to how well it functions as an optical instrument and its performance in the field. Forget about batteries or an external power supply. For the first time ever on a consumer telescope, NexStar Evolution includes its own built-in battery. With this ultra-long life lithium-iron phosphate battery, you’ll be able to enjoy stargazing marathons up to 10 hours on a single charge. You can even use NexStar Evolution’s USB charge port to top off the other devices in your life that need to stay powered on during an observing session. An intelligent power management system senses when battery levels are low and goes into power-saving mode to keep your telescope running for as long as possible. They are better priced and offer great views of the Moon, planets, and other celestial bodies like galaxies and star clusters.Unless you're a seasoned skywatcher and you can afford to go for the more expensive apochromatic — which corrects for such an effect by using exotic glass for the lenses — this degree of color fringing will not ruin your observing experience to any great extent. If you decide to go for the expensive option, you will be stunned by the views you will get through these excellent telescopes. Be warned, though, you might find that some apochromatics come without a tripod, something that you'll have to buy separately along with any accessories. This is a result of my trial-and-error approach to astrophotography. Based on the sound advice from my good friend Steve Mallia at Ontario Telescope, I have decided to use my APS-C sensor Canon EOS T3i (600D) with the iOptron RC6. Because a longer focal length shrinks the area of the sky you see, the larger imaging chip in this DSLR is a better fit with the focal length of the Photron. Whether you're keen on stargazing and astrophotography using just your smartphone, planning to explore dark sky areas with a compact telescope or aiming to dive deep into astronomy with a large Dobsonian telescope, we have you covered. The Celestron Omni XLT 102 telescope uses Celestron's StarBright XLT coating to make the most of incoming light, improving your viewing experience. This telescope also employs aspheric shaping technology to reduce spherical aberration, a common issue that can make light focus improperly. The outcome is crisper, more detailed images that faithfully represent the natural colors of the celestial objects you're observing.

Time to dispel jargon myths with a bit of a telescope glossary. The larger a telescope's aperture (the size of its main lens or primary mirror) the more light is collected and more fine detail is revealed. For example, a 200 mm aperture collects four times more light than a 100 mm telescope. Under ideal conditions, a 100 mm telescope reveals stars down to magnitude +11.8, while a 200 mm telescope will show stars down to magnitude +13.3. A 100 mm telescope will 'split' a double star separated by 1.5 arcseconds and resolves a three-kilometer lunar crater; however, a 200 mm telescope resolves a crater just 1.5 km across and a double star separated by just 0.6 arcseconds. Resolution is limited by the telescope's optical quality and the steadiness of the Earth's atmosphere. Light is collected through the telescope’s aperture and sent toward the next optical piece inside the scope. The larger the aperture, the more light is collected, which results in a greater image resolution. In a reflecting telescope, the light is then passed on to the secondary mirrors, then to the focal point. In a refracting telescope, the light goes from the main lens (aperture) directly to the eyepiece lens. If you put larger and heavier eyepiece, the scope might lose balance, but my recommendation is to remove the viewfinder and use the lightweight red dot that’s better for pointing the scope and fixes the large eyepiece issue.

With this colossal Skyquest XX16g Dobsonian, you’ll be the fun center for star parties and astronomy camps. The battery compartment on this finderscope is located on top of the unit. Use a Philips-head screwdriver to loosen the screw holding the battery door closed. The screw is captured and will not fall out when you open the battery door. If you're looking for a telescope to get started with astronomy, the Inspire 100AZ is a great option. The scope has a 5.1” optical reflecting telescope lens and a focal length of 650mm. It has a Red Dot StarPointer Finderscope and 2 eyepieces, a 25mm, and a 9mm. We were able to see our Solar System and beyond.

Most planetariums and imaging software programs will calculate the most common camera chip sizes for you, or you can do the math for yourself. Richard Wright shared an excellent article on pixel scale for astrophotography in this Sky and Telescope article. Reflector telescopes have a construction composed of mirrors. These large mirrors offer better light collecting capacity. There are no chromatic aberrations and no colored fringes around stars when viewing. On the con side, there may be chromatic aberrations on the images. Refractor telescopes are usually more expensive than reflector telescopes. For Who Each is Best For? If you received a red dot finderscope that looks like the unit pictured here, follow the instructions below to replace the battery:

The Ritchey-Chrétien Telescope Design

Additionally, it uses a planetarium to generate a 'tonight's best' list of different celestial targets and an algorithm to determine the optimum camera settings for viewing each target. Refractors work by bending — or refracting — the light they gather to give you a view of your astronomical target. Easy to set up, the refractor is best suited to planetary and lunar viewing, using lenses to collect and focus light to form an image, while an eyepiece magnifies the view. Planets are also a joy to look at with this kind of scope, mostly because reflectors don’t suffer from chromatic aberration. If you notice any chromatic aberration, it might be from your low-grade eyepiece or from the atmosphere at low altitudes from the horizon. Double stars and star clusters are also very nice to observe with reflectors, particularly with longer focal length telescopes. Deep Sky Objects (DSO) Although the iOptron RC6 telescope presents a new learning curve, it also means that I’ll be photographing a deeper view of space than ever before. The iOptron Photron RC6 Telescope Eyepieces work by magnifying the light focused by the telescope's primary mirror or objective lens. Every telescope eyepiece has a specific focal length (given in millimeters), and the shorter this figure is, the higher the magnification. To calculate the magnification provided by any particular eyepiece on any telescope, divide the telescope's focal length by the focal length of the eyepiece used. For example, a 1000 mm focal length telescope (say, a 100 mm refractor of f/10, or a 200 mm Newtonian of f/5) will deliver a magnification of 100 with a 10 mm eyepiece (1000 divided by 10 = 100).

Refractor scopes are more suited to intermediate to professional viewers as they fall into the higher price range. Now you might be surprised that your eye pupils have an aperture of 7mm and are doing exactly this exact job as you are reading this article. In comparison with a moderately sized telescope, say 60mm, said telescope harvest 70 times more light than your naked eye! Take a look at the dramatic difference in magnification between the following two images of the Pinwheel Galaxy. The version on the left was captured using a crop-sensor DSLR with an 80mm refractor telescope, while the version on the right used the new iOptron Photron RC6. As you can see, an RCT is a much better fit if you want to collect close-ups of smaller DSO’s like the Pinwheel Galaxy.

First Impressions of the iOptron Photron RC6

The Skyline 6-inch telescope offers impressive magnification of up to 133x, allowing you to view celestial objects with incredible detail. Its included eyepieces are well-suited for observing the moon and planets, revealing beautiful finer details. It's a sturdy and user-friendly telescope, making it a great choice even for those new to astronomy. While there are cheaper alternatives available, they often don't match the quality of the Skyline 6-inch. Portability and weight– When you are buying bigger scopes, you must think of portability. This doesn’t affect the viewing quality but can affect your willingness to go out and use it. That’s why sometimes you should pay 20 to 30 percent more for a more compact Dobsonian reflector telescope. Vespera, named after the Latin for 'evening,' sets itself apart from traditional telescopes as it doesn't feature an eyepiece. Instead, it captures and shares captivating night sky images with up to five connected smartphones or tablets using the Singularity mobile app. The Vespera is a camera for taking stunning pictures of deep-sky objects, even in light-polluted cities. It's not intended for observing the moon and planets, but it can be used to capture remarkable images of star clusters, nebulas and galaxies.
