DO NOT USE the 2 x barlow-- just the eyepiece with the largest number written on it. I have never heard of that brand of telescope. Read my TIPS on my profile page.

I can not get the telescope to focus. The viewfinder will not focus in. and can't see anything out of the out of the optical tube.


This type of telescope is viewed from the small tube at the rear. Use the longest lens you have. Most people think that they need magnification, but that is not accurate. A 5 mm lens will only have 1/6th the field of view (how much sky you see) compared to a 30 mm. The picture below was taken through a 50 mm lens.

Can't get image at all thru any lens... ?


where are you pointing your telescope? at night or during the day?
use your widest lens 25mm and up and try to focus on a daytime very distant building or tree more then a mile away , rotate the focus knob slowly one way all the way then back till something appears...this should give you some kinda of image.

Cannot focus the ETX-90. Feel no resistance when I try.


There is a small (tiny) set screw on the side of the knob. Make sure the screw is tight.

How far does it see in the sky


Did you "see" the sun today? Then you looked across 93 million miles without a telescope.

From a dark sky viewing site you can also see the Andromeda Galaxy at 2.5 million light years away--- without a telescope!
