Because the identify suggests, a finder assists you in locating celestial objects. All though the smallest scopes have to have a single. Most popular can be a miniature telescope connected by a bracket close to the eyepiece in the primary scope. It’s got a lower magnification and therefore a broad discipline of see, and is particularly equipped with crosshairs just like a gunsight. At the time you align it accurately with all the primary scope, centering an object in the crosshairs gets it in to the main telescope’s view.
You may need a fairly large, high-quality finderscope. Search for one which has an aperture (entrance lens) larger sized than an inch (25mm) and appears well-made. Dinky, nearly worthless finders are all far too popular on affordable telescopes.
A preferred option is definitely the reflex sight, which initiatives a point or ring(s) of light around the background sky whenever you appear from driving. Many folks favor this intuitively uncomplicated solution, but you happen to be minimal to naked-eye objects since this kind of finder has no magnification and no a lot more light-gathering aperture compared to the pupil of one’s eyeball. You could, on the other hand, nevertheless "star-hop" from naked-eye targets to deep-sky objects using the most important scope at its least expensive electrical power if you have sufficiently detailed sky maps.
Recording what you see, either on film or digitally, can be a rewarding experience. A quality telescope on a driven equatorial mount, a guide scope, and a camera will get you started in astrophotography. And these days taking a photo is only half the fun. Image-processing software lets you enhance your picture to bring out things in it that may otherwise escape the eye.
Assuming you’ve bought a new scope, it’s almost inevitable that you’ll wish to use it to capture the beauty of a planetary image on film or to emulate the marvelous gallery of deep-sky photographs that grace magazines such as Sky & Telescope. In principle there’s no reason why you shouldn’t be able to, given the necessary equipment, inclination, and time. But it’s wise to get used to operating your new scope visually, and learning your way around the sky, before embarking around the astrophotographic adventure.
Photography with the heavens can be incredibly rewarding, but it’s as much an art as a science. The learning curve can be steep, the equipment can get expensive, and getting it right can consume a lot of time. While any telescope will permit you to shoot the Moon, for just about everything else you’ll require a scope on a very rigid, well-engineered, and precisely driven mount.
While it may be tempting, resist the urge to purchase the cheapest telescope available. Most of these are poor good quality optically, mechanically, or both, and will disappoint. If you have a budget of less than $200, consider good binoculars instead.
That said, high-quality instruments can sometimes be obtained secondhand that an experienced member within your local astronomy club may be willing to check out on your behalf. Or have you considered building just one yourself? If you’re gifted with your hands and enjoy working in wood, it’s possible to obtain the optics and make a top-quality Dobsonian reflector yourself. Again, members of your respective local club may help.
Even if you have lots of money to spend, don’t get the largest, most expensive telescope you can find just yet. Commence smaller and more manageable. If you’re just learning to identify the constellations, several in the advanced features of a really expensive instrument aren’t likely to be any use to you. And remember not to get something also heavy to set up, take down, and store.
