The Moon is a ‘must’. As the magnification gets higher, objects get dimmer. The exit pupil is a vital consideration for deciding the magnification of an eyepiece. You are excited about what wonders you will come across? It’s your telescope and the technique that needs some guidance. Look through the finder, and if the target isn't centered in it, adjust the finder. This makes up for the best visual experience for astronomers. The night sky is the most enchanting for astronomers. This is a fundamental law of physics applies to all kinds of astronomy. Well, telescopes can give you the view of what you’re missing. Albireo. Your telescope collects the same amount of light no matter the eyepiece. On these stars, the contrast between them allows us observe subtle and suggestive colours. During the night when the viewing conditions are average, the magnification is 30x or 40x. (DON'T look at the Sun - eye damage!) During the day, find something at least a mile away and aim your telescope at it. Stars appear white is because you can't detect the difference in star color – they all emit white light. A low-powered eyepiece has a wider field of view. Realistic image of M81 and M82 galaxies through an amateur telescope. The low brightness of the celestial objects makes unlikely to see colours in the sky. Realistic image of Saturn through an amateur telescope. As soon as I insert any lens (one of those approx 1" long items 20mm, I have a couple different ones.) You may believe this to be true but it is not. We will be able to count dozens or cents of stars. When I bought my Celesteon 130EQ I faced the same problem. You can also pan the handle of the scope for stability. Hi Moi, Thank you for your comment, but I have to disagree. Whereas in a reflector telescope, it is present at the front-side end. Here are some solutions to your problem. The 10 Golden Rules of the Astrophotography. Do not place your eye right against the lens of the eyepiece. Your observation will be as clear as day, even during night-time. Can you see it OK? The answer is ‘yes’, you can although depending on the optical system, the image can suffer some mirror effect; we could see everything upside-down or inversed the right to left when we point to something  on the ground. I'd realign the finder. Even a particular situation can ruin the view if you are not careful. The best example of double star on the northern hemisphere. Color exists because the wavelength of it causes a response in our eyes. To avoid confusion, low powered eyepieces have higher calibration. When an astronomy newcomer asks us: What can I see with a telescope? A red dot finder displays a wide field, zero magnification view of the sky. Both issues can be addressed by moving the main tube around a bit, so as to catch the target in its field of view. Finderscopes can either be “straight-through”, as shown in the photo to the left, or right-angle, allowing the user to look down to see through the finder rather than positioning your eye behind the finder in a line-of-sight manner. With the eyepiece holder how it extends in and out. After you are through with this article. This may be the time to increase the magnification. I just bought my telescope today and set it up according to the instructions manual. Credit: GalaxiesSoup.com. Looking through this, but a couple inches away from eyepiece, I can see my hand waving at the end of the telescope and the light. Save my name, email, and website in this browser for the next time I comment. Now, we have to explain what you can see. It’s your telescope and the technique that needs some guidance. Finally, we have to tell our friend what he can observe beyond the Solar System, what we call Deep Sky… and now the explanation becomes more complex. 1.)
