Bushnell Telescope 78-4678


A telescope like that has a very narrow depth-of-field, so you need to focus very, very slowly to be able to see any image. Try focusing on something bigger (like a spot on the moon) and adjust the crosshair accordingly. The two eyepieces gives different magnification.

I HAVE BOUGHT TELESCOPE BUT I AM NOT ABLE TO SEE THE STARS CLEARLY AND EVEN THE MOON WHICH TYPE OF LENSES I SHOULD USE TO SEE THE STARS CLEARLY


Stars are always JUST points of light with or without a telescope. They are too far away to see a disk.Try to find Jupiter a bright "star" in the WEST after dark.And also the Orion Nebula- M42.Download this free monthly star chart:www.skymaps.comand read my TIPS on my profile page

Wrong manual I have the bushnell computered star locator northstar.. no numbers.. I was hoping i would be put in the ballpark. I took a shot, i was wrong. I have no manual. This is about 5 years old, never used,because it never work. I don't even know how to set the lenses to see out of it


Here are the Bushnell manual for Northstar:http://lib.store.yahoo.net/lib/opticsplanet/northstargotorvo.pdf

Why can I not see the difference from the sky and a star even when I allign my laser well?


It sounds like you have not adjusted the focus properly. I recommend you take your telescope outside in the daytime and point it toward a building or tree or hilltop that is somewhat distant from you. The exact distance is not important, but it should a block or more. With the telescope pointed at the distant object, focus the telescope until the object is sharp and clear. The object might appear upside down -- that's normal for many astronomical telescopes. When you have achieved a sharp focus, leave the focus control alone until you are outside at night under the stars. The focus should now be fairly close for viewing stars and planets. Small adjustments of the focus control may still be necessary for the sharpest view. - Jeff

We have our telescope set up but cannot see anything out of the lenses. we have tried all different lenses but without success. Currently there is one star we can see with our naked eye. We cannot see it through our telescope. thanks the osborne family.


If you look at the PICTURE in your qusetion FIXYA has the scope POINTED at the ground! :)You have a reflector style telescope. The mirror is the bottom of the scope, and the focuser is on the UP end of the tube pointed UP. Many beginners mount these scopes UPSIDE DOWN with the focuser on the bottom instead of the top (side) of the tube.Put the eyepiece with the largest number written on it into the focuser. DO NOT use the 2x barlow if you have one. Take the scope outside during the day time and practice focusing on a distant object. You must also line-up the small finder scope on top with the main tube. POINT the scope at the top of a distant telephone pole. Without moving the main tube, adjust the cross-hairs on the finder scope so they point at the same spot as the main tube.Read my TIPS on my profile page.

Hi i can use the focus scope to focus but the eyepiece lenses are still blury This is my first telescope and i want to star and planet watch with it. I can see and focus the focus scope but upon looking into eyepiece with barlow lense with h20mm attach it is fuzzy and blury cannot see anything thankyou


Don't use the barlow - it's too much magnification for such a small telescope.

Can't see anything through the lens?


Put the diagonal into the telescope-- then put the eyepiece that has the LARGEST number written on it. This is the lowest magnification. DO NOT USE THE BARLOW 2x multiplier !!Take the scope outside during the day time and practice focusing on a distant object. The moon should be the first night time target you try to see.
