1. During the daylight point the telescope towards an object (water tower, building ) something about 1/2 mile away. 2. Locate the object in your finder. 3. Use the 12.5mm lens (50x) and look through the telescope. Do not use the erect prism 4. Align the finder to what you see in the scope. 5. You can use the 4mm to fine adjust the finder. 6. On a good, clear night.Leave the scope out to reach thermal equilibrium ( about a hour) Point the finder towards the moon 7. Use the 12.5mm and then focus on the moon.
Note: This is NOT a quality scope. Avoid any scope with .965 eyepieces and silly magnifications! Max power on this scope on a PERFECT night is 200x and Huygens (H12.5) eyepieces give very narrow and poor viewing. Do not use the 3x barlow or the erecting prism. the erecting prism is for terrestrial viewing only and the barlow, although it increases the eyepiece by 3x, will also narrow the view. Good Luck!
First WHY would you use a erecting DIAGONAL in a reflector style telescope. Upside down images are completely normal for an astronomical telescope. You only need this diagonal for terrestrial viewing NOT for star gazing. ALL astronomical telescopes show upside down and or inverted images- it's completely normal.
If you cannot come to focus with the erecting diagonal, it's probably because the diagonal moves the eyepiece too far OUT away from the point where the scope comes to focus. Again-- you do not use those for night time sky viewing. Just stick the eyepiece directly into the focuser.
Is this your telescope? http://www.binocularsdirect.com/Bushnell_Telescopes/dptsmzmyqcq.html
Can you try replacing the eyepieces on the side with the one on the back. Also if you "slightly" slide the eyepiece OUT does it come to focus?
I must tell you this is a very unusual design with a turrent AND another eyepiece on the back. Has the rotary eyepiece module become loose from the back of the tube? Can you push it in closer to the tube?
Other than forward or backward adjustment that's all the focuser will do.
No no manuals. The smaller the number written on the eyepiece the GREATER the magnification.
However many astronomical telescopes show everything upside down. This is normal -- no up or down in space. You can buy and erecting prism diagonal for terrestrial viewing which will turn the image right side up.
Probably -- the 4mm gives too much magnification for you telescope-- difficult to focus or find thing in the sky-- you should also have had an eyepiece somewhere between 17mm and 24mm for lower power viewing.
Try the other eyepiece first-- no one can fix that scope which is imported. No repair facilities or replacement parts. Next time stay away from those types of scopes-- buy from one of these NORMAL scope retailers--
The moon is big so use the 25mm. The Barlow will have a multiplication marking on it 2x 3x etc. A 2x Barlow lens will effectively double the power of the eyepiece you are using. Do not use the erecting eyepiece for anything other than land viewing. Erecting eyepieces generally reduce the amount of light reaching your eye and thus reduce brightness of the faint objects in the sky. So basically just place the 25 mm lens in the focuser and point the scope at the moon and you will be amazed at what you can see and how bright it is.
