SOURCE: New bushnell telescope, cant see anything, what am i doing wrong?

Put the lowest power eyepiece in the telescope-- that's the one with the LARGEST number on it.

Go outside and practice focusing on a distant object at least 100 yards away-- turn the focus knob slowly.

The erecting prism can be used for both terrestrial and star gazing-- put it innto the scope first.

The 3x barlow probably will NOT be very useful... it triples the power of any eyepiece. Your small scope cannot go much over 100 power-- before the image degrades.

Put the eyepiece with the BIGGEST number written on it into the erecting prism which you previously stuck into the scope... now go outside during the daytime and practice focusing on a distant object.

The bigger the number on the eyepiece the LOWER the magnification.

I am having trouble seeing through the 60mm Objective Lens. I'm able to see clearly through the Finderscope. Also how do attach the Barlow and Erecting Lens?

You put the prism into the focuser and then the eyepiece with the largest number written on it. DO NOT USE the 2x barlow until you learn how to focus properly.

One answer advises NOT to use the "barlow." A

A Barlow lens doubles (or trebles) the magnification, but it also degrades the image. You are better off without it. People tend to buy telescopes on their magnification figures, even though these are essentially meaningless, so junk like Barlows get added to the package to increase the advertising impact. The mere fact that one came with this telescope tells you that the quality is not wonderful.

The specification that means something in a scope is the diameter of the objective (the main lens or mirror). Magnification is just the focal length of the objective divided by the focal length of the eyepiece. You can usually see more at lower magnifications, as the resolving power of the objective is often less than the advertised magnification. A smaller distinct image is better than a big blob of fuzz. That's why you were advised to try the scope first with the larger number (lesser magnification) eyepiece.

But try out the Barlow and see for yourself.

Cannot see through the lens of a 565 bushnell telescope

Did you remove the lens cap.

This is a simple refractor telescope. Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow if you have one.

Practice focusing on a distant object during the day time. Read my TIPS on my profile page.

Yes it will focus --- put the eyepiece with the LARGEST number written on it into the scope. DO NOT use the 2x or 3x barlow.

Practice focusing on a distant object at least 100 yards away during the day. The moon should be your first night time target.

Practice focusing during the day on a distant object at least 100 yards away-- use the eyepiece with the LARGEST number written on it-- and DO NOT use any 2x or 3x barlow to multiple the power.

The moon should be your first target at night.

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.

Upside down images

ALL astronomical telescopes show upside down images it is normal. Put the eyepiece with the LARGEST number written on it into the diagonal. Do NOT use the 2x barlow it is too much magnification for that small aperture telescope.
