You'll need something larger than 4 or 5 inches if you want to take your stargazing to the next level and see fainter deep-sky phenomena like star clusters, galaxies, and nebulae. For a complete beginner, a telescope of this size is absolutely a great place to start. With a scope this narrow, seeing Neptune and Uranus can be challenging, but it's not impossible. The planets, the Moon, and Jupiter's moons may all be seen clearly by telescopes with a 4 or 5 inch diameter. The telescope can view fainter objects and can reveal more detail on nearby, bright objects like the Moon, the larger its diameter. When selecting a telescope, the aperture-or the diameter of its primary mirror or lens-should be your top priority. But it will be much simpler to choose a telescope in your price range that you will use the most if you have a basic understanding of the various telescope sizes, kinds, and mounts. It's simple to get swept up in the thrill of a new telescope and neglect to consider how useful it will be for your way of life. It has recently captured its one-millionth image, and given time it just might capture a million more.What makes a good telescope - Are you considering of purchasing your first telescope? There are so many options to consider when you first start your search, which can be overwhelming. Of course, with a decade of work under its belt, the DECam has no intention of stopping any time soon. It’s an amazing demonstration of what the DECam can do. Then combined and colorized these images to create the final image. To capture the details of this image, the DECam team used narrow band filters to take images of specific colors within the nebula. The image spans about 400 light-years and shows bright young stars among dense regions of gas. Blanco telescope at Cerro Tololo Interamerican Observatory (CTIO) in the Chilean Andes. You can see the results in the image below, which is pretty stunning. It’s about 8,000 light-years from Earth in the constellation Scorpius and is an intense star-forming region. So the team pointed it at the nebula NGC 6357, also known as the Lobster Nebula. A high-resolution wide-field camera is great for capturing data, but it’s also pretty good at capturing some amazing images. Hahn/CTIO/NOIRLab/NSF/AURAīut as DECam reached its first decade of operation, the team decided to do something a little different. The DECam mounted on the Blanco 4-meter telescope. This data has given us a deeper understanding of dark energy and helped astronomers constrain observations so they can better fit theoretical models to observation. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, where it has a field of view more than 2 degrees wide, which is four times the apparent width of the Moon.īetween 20, DECam captured an average of 400 – 500 images a night, looking at distant supernovae, measuring the scale at which galaxies cluster together, and studying the weak gravitational lensing of intergalactic dark matter. It is the highest resolution astronomical camera ever built, with more than 60 imaging CCDs, and captures images at 570 megapixels. This is why ten years ago the Department of Energy worked with astronomers to build the Dark Energy Camera (DECam). So to study dark energy in detail, you need a great deal of observations of wide areas of the sky. It drives the evolution of the cosmos, but its effects are only seen on intergalactic scales. Dark energy is perhaps the most subtle phenomenon in the universe. If you thought dark matter was difficult to study, studying dark energy is even more challenging.
