Question about Celestron FirstScope (150 x 76mm) Telescope

1 Answer

When looking through I can see the shadow of the little reflector inside it. We focused in on a star and saw it perfectly but we also couldn't figure out why we were seeing the shadow of the little mirror inside the tube.

You are not in focus! Was the star ROUND and looked like a donut? Stars are pinpoints of light. They look the same through any size telescope-- exactly the same as without a telescope!

Try focusing on the moon next time.

I lost the manual. how does it work ??!!! i think i've lost some eyepieces as well.


This is a very simple REFLECTOR style telescope. The reviews are very bad-- see this:
http://www.amazon.com/Cstar-Stratus-UB-3700-Reflector-Telescope/dp/B00025VYO4

Simply put the eyepiece with the largest number written on it into the focuser and practice focusing during the day time on a distant object. There is no manual for this scope anywhere on the internet-- it is a very cheap low cost imported telescope.

Also the tripod is way too small and shaky.

Star Diagonal (For 1 1/4 lense needs closer focus than telescope will allow.


You do not need a diagonal with a reflector style telescope. Just put the eyepiece into the focuser.

When viewing venus or other stars there a black spot in the center of the object. It appears to be the 2nd mirror refleting to the main miror. what have I done incorrect?


You are NOT in focus. Turn the focus knob a little until you see a perfect "disk" for the planet. Stars are always POINTS of light, with a telescope or without a telescope.

Can't figure out how to put the eye-pieces (3) on our Selsi Telescope 335x.


All eyepieces go into the FOCUSER end of the telescope. You never said if this is a REFRACTOR or a REFLECTOR style telescope.

On a refractor you have a lens in the front and the focuser in the back.

On a reflector the focuser is on the SIDE of the telescope near the front end.

The diagonal goes in first --- and the eyepiece goes into the diagonal -- if this is a refractor style telescope. Here is a picture of the DIAGONAL.

I picked up a used Meade 114 EQ AS on the off


First go to Meade's manual web site -- look under the REFLECTOR heading and download a manual. Here:

Second-- It's NOT ASTROLOGY! It's Astronomy!

Astrology is completely fake and superstitious belief that the planets and stars affect your life!

The MIRROR is on the bottom of the telescope- this is called a REFLECTOR style telescope. The focuser is on the TOP (side) of the telescope. Make sure the focuser end is UP and the mirror is on the bottom pointed toward the GROUND.

Telescope: can't see anything except shadows


Put the eyepiece with the LARGEST number written on it into the telescope and take it outside during the day time and practice focusing on a distant object. DO NOT use the 2x barlow if you have one.

You never said what type of telescope? Is this a REFLECTOR with a mirror inside? or is it a REFRACTOR which has a lens mounted on the front.

4.5 inch reflector telescope --can't see anything


Try pointing it at the moon first-- with the 20mm and practice focusing it. The moon is up just after dark right now.

Obscured view through telescope


You can slow down dew forming on the mirror by NOT pointing the telescope toward the sky during cool-down-- just leave it parallel to the ground. Same goes for your eyepieces -- leave them covered, or inside a case.

Direct Sunlight...


Try adding a bit of fill in flash. It's difficult in direct sun, as if the sun is behind YOU the subject may be squinting. If the sun is behind the subject you will need lots of flash to compensate for the face being in shadow.

If you are posing the shot, put the sun behind and to one side of the sitter and use a good reflector to bounce light back toward them with the reflector at eye level. The reflector does not have to be a special bought item. A sheet of really thick whit card, taped to a tripod will do just as well.

If you are taking pics on the go and can't lug equipment around with you, meter on the face, use a little fill and bracket a stop either side to make sure.
