The OPTeam will be glad to steer you towards the best possible telescope to begin your journey into the world of astronomy. Best Refractor For Astrophotography Achromatic Refractors AR Apochromatic refractors APO Sky-Watcher Pro ED 80mm Doublet APO Refractor Telescope. If you have any questions about purchasing a telescope or need to know more, please contact us. ![]() Schmidt-Cassegrain refracting scopes with these features are a popular choice for both beginning and advanced deep sky astrophotographers. What size telescope do I need to photograph galaxies?įor photographing deep space objects such as galaxies, you’ll need a telescope with a short focal length and a large aperture for collecting as much light as possible. ![]() If you’re interested in planetary photography, you’ll want a telescope with a focal length of around 2000mm and a slower focal ratio, such as f10. Which focal length telescope is best for astrophotography?įor deep sky astrophotography, consider a 4–5-inch refractor scope with features for flattening and eliminating coma and other optical aberrations. Consider a reflector telescope with an aperture of 8 inches or more with computerized tracking features that help you locate deep space objects like galaxies and nebulae. Seeing galaxies and other deep-sky objects such as nebulas requires a telescope to capture plenty of light. Which telescope is best for seeing galaxies? Consider a refractor telescope with tracking and locating features that help you zero in on the object you want to view. Telescopes designed for deep space viewing typically have large apertures, and a shorter focal length than scopes meant for planetary viewing and imaging. What is the best telescope for deep space viewing? To capture the most detailed images of objects in our Solar System, consider a Schmidt-Cassegrain telescope or a Dobsonian, with its stable mount and easy tracking of objects. ![]() Planetary imaging requires a telescope with a large aperture and a longer focal length than telescopes designed for photographing deep space objects. What is the best telescope for photographing planets? Advanced astrophotographers might prefer the high-quality optics and flatfield features of triplet and quadruplet Petzval refractors, designed to capture detailed images of very distant deep sky objects. If you’re a beginner, an all-in-one setup with a large aperture can get you started with planetary and lunar photography. Used in universities and observatories around the worldįAQ: What type of telescope is best for astrophotography?.Spherical secondary mirror allows effortless, solid collimation.Professional grade quality in a consumer instrument.It comes with a compact, stand-alone Alt/Az mount that’s intuitive to use without polar alignment, and its direct drive motors provide error-free, fast tracking that also counters wind gusts. The PlaneWave CDK500 brings observatory quality and precision to consumers with Fused Silica primary and secondary mirrors and a 52mm field of view with no field curvature, off-axis coma, or astigmatism. Watch our laser collimation tutorial for more information.PlaneWave CDK500 (20-inch) Telescope System - $54,000 Thankfully, there are quick and easy ways to collimate a telescope nowadays. You will need to learn how to collimate the mirrors if you are purchasing a reflector telescope. It needs to be collimated - This is probably the most important point. ![]() It is much larger and heavier - Don't expect to carry it with one hand! It is also 17.5 pounds, which is 10+ pounds more than a small refractor. If you don't care about very large targets (like the Heart Nebula or the North America Nebula), then you'll like being able to capture smaller objects. It has a longer focal length - This can be a good or a bad thing. It is much faster - This telescope has a focal ratio of 3.9, which is very fast! The fastest refractor in the list above is 4.5, but most small refractors have a focal ratio of 6. It is much cheaper - The Orion 8" Astrograph costs $499 ($479 when on sale, although as of 2023 the price is now in the $600's.), making it the most affordable telescope in this list.
