The Magdalena Ridge Observatory 2.4-meter telescope is primarily utilized to observe, track, and characterize solar system astronomical targets, artificial Earth satellites, space vehicles, and terrestrial military targets. We're always here for you. While there are some exceptions to the rule, achromatic refractors use two lenses in their design, and while they are economical, achromats are only capable of focusing two out of three wavelengths of light. The NexStar 8SE is a portable Schmidt-Cassegrain computerized telescope that is easy to use and has 8 inches of aperture to see deep into space. Objects that were in sharp focus at a particular magnification on Saturday night may not come to focus with the same eyepiece on Sunday. Below is a list of activities you can do with a telescope to help you decide: Most people use their telescope from the comfort of their own backyards, and most set up their telescope each time they plan to use it.

If someone dreams of looking at galaxies, shoot for at least a 4-5" telescope Bigger is better and will increase the detail as well as the number of deep sky objects one can see, but of course more aperture increases the price and the size/weight of the telescope system. The focal ratio signifies how quickly a telescope gathers light and tells us something about the telescope's field of view, how long exposures will take during astrophotography sessions, and how much magnification the eyepiece will produce for that telescope. The point is, if you want aperture, portability AND electronics, look into a Schmidt-Cassegrain or EdgeHD telescope in the size you'd like, and then choose whether to have it ride on an equatorial mount and tripod or a computerized alt-azimuth mount and tripod. .
