In the past several years, however, many stargazers looking to see more have turned to an alternative to visual observing with ever-larger telescopes: electronically-assisted astronomy (EAA).ĮAA involves the use of electronic aids for the enhancement of astronomical viewing while at the telescope in nearly real time. This line of thinking, which is quite understandable, inevitably leads to "aperture fever", the desire for bigger (and more expensive and cumbersome) telescopes. What is confusing me is that various pals in CN have told me they simply affix a regular (40mm long) Celestron visual back to the Celestron focal reducer and (fully) plug the camera's 1.25' nose-piece into that and it works, despite back focus from the Focal Reducer then being only being around 50mm (e. It's something every amateur astronomer thinks at the eyepiece of their telescope: "I wish I could see just a little bit more." More detail, more light, and more deep-sky objects instead of the same old showpiece sights on the same old observing list year after year. The new Baader MaxBright II Binoviewer, successor to the discontinued MaxBright I, is marketed as a mid-tier binoviewer that fills the gap between more inexpensive entry-level binoviewers (Celestron, William Optics, Orion, etc. A f/10 focal ratio now achieves a f/6.3, while an f/11 focal ratio now achieves a f/7. For this I used 4 eyepieces, Pan 41 Pan 35 ES 34 68 and Agena Astro SWA38. Explicitly designed for Celestron Schmidt-Cassegrain telescopes, this unique lens reduces your telescope’s focal length and f/ ratio by 37, turning your long focal length telescope into a fast, short focal length instrument.
