![]() ![]() This camera is an older model of the D5600, but with the same sensor. ![]() I've bought used cameras and lenses from KEH and always been pleasantly surprised at how the cameras were always in better shape then their used ratings.įor those on an extremely limited budget, you can buy a used Nikon D5300 for $300 to $350 with an Excellent rating at KEH. Used models can also be considered for significant savings. I have purchased many refurbished cameras from Canon without any problems. Refurbished models usually come with a 90-day manufacturer's warranty and are basically new cameras that have been returned for one reason or another but that can't be sold as new. The Canon T7i and Nikon D5600 both have a tiltable LCD screen on the back, a feature that is really nice for astrophotographers when you need to focus with the camera or lens pointed overhead. Here I suggest the two very inexpensive camera models that, while no longer in production, can be found used with very attractive prices. So we start out recommendations at the > level up. Some do not have tilt LCD screens on the back. Some can not be controlled externally by a remote release or computer. However, these models usually lack some feature that is important for astrophotography. Recommended Beginner Cameras Recommended Inexpensive Beginner DSLRs for Astrophotographyīoth Nikon and Canon have entry-level camera models that are the least expensive bodies they sell. Some of these cameras can also output raw, uncompressed video to an external recorder.Īll of the images below were captured with DSLRs. The latest cameras with high-definition video might also be able to be used if a video mode can be found that outputs 1:1 pixel resolution that is not interpolated or decimated. Other cameras can be used, typically by capturing Live View at 5x magnification to get to 1:1 pixel resolution, but you must use a computer at the scope to use this trick. These cameras have a special "Movie Crop Mode" that gives 1:1 pixel resolution at 640 x 480 pixels off the sensor at 60 frames per second, recording directly to the memory card in the camera, so you do not need a computer at the scope. You don't need a large sensor for high-resolution planetary photography because the planets are small even when magnified to the correct sampling for the size of the pixels in the camera.Ĭertain DSLRs can also be used for high-resolution planetary imaging such as the Canon T2i (550D), 60D, and 60Da. These objects are bright, so exposure is not the problem, but good "seeing" or atmospheric steadiness is critical.Ĭameras with small pixels and high frame rates that can output uncompressed high-bit raw video are the best. Planetary photography requires larger apertures to pick out tiny details on planets such as Jupiter and Mars, as well as small craters on the Moon and details in sunspots. High-resolution planetary photography records fine details on the Sun, Moon, and planets of the solar system. But modifying the camera will void the manufacturers warranty, and require the use of a custom white balance.īest Cameras for High-Resolution Planetary In some cases it may even be less expensive than buying an "a" model astrophotography camera. It is also possible to have your current camera, or other regular stock non-astro cameras, modified to replace the long-wavelength filter and record more red Ha wavelengths by companies like Life Pixel and Kolari Vision. In specialty astro-cameras, such as the Nikon D810a and the Canon Ra, these filters are replaced with ones that transmit much more red hydrogen-alpha wavelengths at 656.28 nanometers. ![]() Camera sensors are sensitive to these wavelengths, but a filter prevents them from reaching the sensor. ![]() Normal stock DSLR and Mirrorless camera filter out most of these long red wavelengths because the eye is not sensitive to them and camera makers want color out of the camera to represent normal human color vision. Red hydrogen-alpha emission nebulae are some of the most beautiful nebulae in the sky, and they can also be very large. Best Cameras for Hydrogen Alpha Emission Nebulae ![]()
