Thankfully, you wont 3.5x as much (reflectors are cheaper to make than refractors) Expect the 70mm AstroMaster to cost around 120 - 140 ( click here for current price ). You can use any good quality telescope to photograph the Moon, but large aperture Schmidt-Cassegrains and Maksutov-Cassegrains are popular choices with lunar photographers. The 130mm aperture models offer 3.5x the light gathering power of the 70mm model. For fainter, smaller nebulae, scopes of at least 8 inches and focal lengths of 1000 mm or more are recommended. Celestron AstroMaster 130mm Group Review. Use scopes of at least 8 inches (200 mm) and focal lengths of less than a 1000 mm for faint, larger nebulae. Some are also very large–many degrees across. By clicking on each row it is possible to view full details for each planet. If planets are more desired, you will need a telescope. It is a totally manual lens which is what astro photography needs. I bought a 400mm Asahi Pentax Takumar f5.6 m42 mount that works quite well for example. On the other hand, faint nebulae demand larger aperture just to capture enough light to see them. This table shows current essential information about the planets. Planets wont be so large, but you can see some deep sky objects. Use apertures of 5-8 inches (125 to 200 mm) with focal lengths of 1000 mm or less. Why It Made The Cut: The EvoStar’s large aperture, powerful magnification, and easy-to-use focuser make this option the best telescope for. 1 StarSense Explorer DX 130AZ Smartphone App-Enabled Telescope Works with StarSense App to Help You Find Stars, Planets & More 130mm Newtonian Reflector iPhone/Android Compatible View on Amazon SCORE 9. (This is because they will usually have longer focal lengths, resulting in higher magnifications and smaller fields of view with typical eyepieces.) For bright nebulae, choose medium aperture scopes with relatively short focal lengths to capture the entire gas-dust cloud in the field of view. Best for Astrophotography: Sky-Watcher EvoStar 100. The only sacrifice going to larger scopes is the loss of a wide field of view encompassing the entire nebula. Larger scopes targeting this nebula and other objects of its class will reveal details that cannot be seen in smaller scopes. The bright, larger ones like the Great Nebula in Orion is best seen in relatively small scopes. Nebulae: Clouds of gas and dust vary enormously in size and brightness.
