How To Use A Telescope For Beginners
The offending component can be identified by rotating it about its centre, whereupon the astigmatic image will rotate too. If the focal length of the telescope is 900 mm and the eyepiece has a focal length of 20 mm, its magnification on that scope will be 900 divided by 20, But if the collar doesn't grip the tube, pack it out with tape (above) To focus a finder scope, loosen the locking ring on the left then turn the dew cap Now its quite probable that the finder scope needs aligned to the scope, so they are both point to the same object.
Can’t see anything at all? The refractor's objective lens (the big one at the top of the tube) and the Schmidt-Cassegrain's corrector plate (the window-like covering at the top end) can be cleaned as follows: If Please consider giving today. In 2013, we evolved to add video, and in 2015 we joined the International Year of Light. https://au.answers.yahoo.com/question/index?qid=20090222031841AAf8VEz

Contact lens wearers may see pearly-looking haloes around bright objects if their contact lenses are not clean. Bright objects have "ghosts" Your eyepiece may not have anti-reflection coatings on its I just couldn't get it in the scope. The image will be inverted, but that doesn't matter since you're just checking the focus. wikiHow Contributor Make sure you aren't in a light polluted area first, but if that's not the case, be very careful in your focus adjustment.

- As a result, you're pointing the scope a bit off the target, and end up looking at a region with nothing interesting/bright.
You can only upload files of type PNG, JPG or JPEG. Then slightly loosen the screws of the finder scope and gently adjusting them to bring the same small object into the centre of view in the finder scope. Also, while it is still light outside, ensure that the finder scope cross-hairs are aimed at the same point as the main tube. I Can't See Anything Out Of My Telescope We figured out the finder scope was misaligned.
Use covers on the ends of the telescope tube, and return eyepieces to their storage containers when not in use. How To Use A Reflector Telescope If your mounting is strong, durable, doesn't wobble, is immune to breezes, holds the telescope safely, and allows it to move smoothly and controllably; then it's a good mounting. If you have a Schmidt-Cassegrain you can collimate them by adjusting the tilt of the secondary mirror and (sometimes) the primary mirror. And don't expect a finder scope to be properly aligned (or to stay aligned).
So say you have a 6-inch reflector. 300-power is as high as you should go (for a 3-inch reflector it would be about 150-power). Telescope Won't Focus When your telescope is properly collimated, the view should resemble this final diagram. It's best to see in the half-moon. Outdoor lighting in Australia is controlled by three Standards.

Get More Information Yeah, I'm very new to this and I've got a reflector/refractor telescope (the one that uses mirrors), but when I look through it, all I can see is black.

Australia huh If you are in/near to Sydney, I would be happy to give your family some hands on practical help with the scope and also in finding your way around It looks like this particular model [EDIT: DOES NOT FEATURE] a robotic go-to mount [EDIT: BUT SINCE SOMEONE WITH A SIMILAR PROBLEM MIGHT HAVE ONE...] Did you follow the alignment software If possible, the telescope should be aimed upwards when removing the mirror cell. reversed or "mirror image") is also normal for telescopes with an ODD number of reflections; such as Schmidt-Cassegrains (primary mirror + secondary mirror + eyepiece diagonal) and most refractors (eyepiece diagonal).
Y'know what I mean? How To Focus A Telescope Don't just cut off the canister base -- many canisters lose rigidity if this is done. Then empty the sink.
Protecting the optics from airborne debris will make a big difference to their longevity.
Always keep it completely covered when not in use to keep dust off of the mirror.

Are the optics clean? Share this thread via Reddit, Google+, Twitter, or Facebook Have something to add? Install an eyepiece and slowly rack it all the way in and all the way out to see if you get anything at all in the lens. Mistake number nine is to stare right at the object you are trying to see.

Using different eyepieces Once you’re happy with using the lowest magnification, the natural thing is to want to increase the magnification.
I suggest downloading the Google Sky app (or other similar program) on a smartphone if you have one. Some junk telescopes suffer from internal reflections inside their tubes, because the manufacturer didn't bother to paint the inside of the tube black. Everything's upside down and/or back-to-front! DOES THAT MEAN WERE GONNA DIE???!1! Even a stable tripod is unhelpful if the parts connecting it to the telescope tube are badly designed (or built).
Or buy the equivalent "terrestrial" or "spotting" scope model. It's also exasperating to aim at anything. Añadir a Cargando listas de reproducción... Place some folded towels or other padding around it, in case it falls over!
While it is true that many have been hooked on skywatching for life by viewing the wonders of the night sky through their first scope, it is also true that many One of my friends found her cat asleep inside her telescope tube one night.
