In case you have already tried shooting with telescopes at night, you have probably faced the difficulties with focusing. Sensor size and focal length collaborate in order to specify the precise part of the sky that can be captured. Consequently, bigger sensors offer wider field and smaller imaging chips narrow the field of view. Shorter focal length extends the part of the viewed sky while larger focal length diminishes this area because of the bigger magnifying ability. This parameter depends on the size of the chosen camera’s imaging chip and the focal length of the optics. The best telescope for astrophotography is capable of reaching a certain part of the sky. Type of Imaging You Are Going to Doĭo you want to concentrate on the Moon or are you interested in the overall look of the sky? Are you aiming at deep-sky or wide-field imagery? Answer these questions and select the suitable focal length and aperture. Besides, it may quickly adapt to different temperatures. The focusing isn’t problematic, the color correction is outstanding. It is of small dimensions, light weight and is easily transported. This feature makes it possible to achieve impressively clear pictures with no chromatic aberrations. It either combines curved mirrors or features one mirror, which make up a picture and reflect light.Īn apochromatic refractor has an extra-low dispersion glass. Type of TelescopeĪ reflecting telescope is often referred to as a reflector. ![]() Hopefully, the information presented below would help you save money and remain satisfied with your choice. Actually, every part of this device is important and affects the process and results of both stargazing and shooting. If you believe that choosing a decent telescope for astrophotography is pretty simple, unfortunately, you are wrong.
