All astronomical telescopes show upside down images-- it's normal, nothing is wrong with the scope.

Read my TIPS on my profile page-- this is one of the most frequently asked questions. Remember NO up or down in space.

Where do i put the film on a telescope


Do you mean how do I take photos with a telescope?

1. For bright objects like the planets, or the moon you can use a cell phone camera. There is a telescope attachment available to mount the phone directly over the eyepiece.
2. For long term photos- the telescope MOUNT is more important than the telescope tube. It must be able to track the sky VERY accurately for up to 5 minutes.

For starting out stay with bright objects -- you can use any type of digital camera -- so experiment.

I got this telescope for my daughter and the instruction manual was accidentally thrown away. We think we got it put together but as we look into it, everything is upside down. Can you please help or is...


This is correct unless you have a diagonal mirror. This is a 90 degree elbow looking thing that goes between the eyepiece and the telescope. It has a mirror inside that flips the objects right side up. I looked on the internet but could not find a manual perhaps where you got it from might have a source.

I just received as a gift, set it up and nowI am unable to see anything. the instruction manual is vague, only tells me how to set it up but not much else. thanks


The manuals DO NOT tell you how to find objects in the night sky, they are only assembly instructions. Wish you had not bought that telescope, this type would have been better for a beginner.

Take the scope outside during the day time and put the eyepiece with the largest number written on it into the focuser. Practice focusing on a distant object. The moon should be your first target at night.

Locate an Astronomy club nearby and the members will help you learn the sky. All sky objects are smaller than the tip of your finger held at arm's length. The scope must be pointed directly at them to see anything.

When I look through the lense everything is just black


Take the scope outside during the day time. Put the eyepiece with the largest number written on it into the TOP diagonal. There is a "flip" switch on the back that changes between the rear photo port to the TOP eyepiece port.

Flip it one way or the other until you can see light through the TOP eyepiece. Practice focusing on a distant object during the day time.

Here is the manual:

You are using too much magnification. Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow if you have one. Take it outside during the day time and practice focusing on a distant object.

Image is upside down (inverted)


All astronomical telescopes show upside down images this is normal.

You can buy an "erecting prism" to use for terrestrial viewing from many on-line retailers here is one: This will flip the image so it is not upside down.

Want to see images right side up


You do not need an erecting prism to view objects at night. These are used if you wish to view terrestrial objects since it turns them right side up.

If you have a reflecting telescope (it uses mirrors) it's normal to not use an erecting prism or as they are also known as star diagonals. Objects will appear inverted and that's normal. A refracting telescope (no mirrors, just lenses) will also invert the image but it is quite often used with a star diagonal to make it easier to view. There are many other types of telescopes that use a combination of mirrors and lenses.

I hope this helps.

My son got a telescope and we are unable to focus on anything.


Use the lowest magnification eyepiece which is the one with the largest number on it--- DO NOT use the barlow which will DOUBLE the magnification!

Go outside and focus on a distant object (during the daytime) and practice focusing the telescope. Move the focus know slowly in and out until you get a sharp image.

No you do not have anything wrong. When ever light is passed through a lens it is inverted. Binoculars, and land viewing telescopes use a special lens combination or "erecting" prism to flip the image for you. The problem with that is it reduces the amount of light that passes through the telescope. It's not an issue for land viewing because these things tend to be close and bright. For astronomy objects are so faint that you actually get a better view when things are upside down.

Is it a Webley or a Eley Colt .455? How to tell if the cylinder bore has been modified to accept Colt 45 or other ammunition. Obvious the barrel (8" smooth bore) and sights were replaced Please help an ole man out that happens to know "Nothing" about Colt Double Action Revolvers... At 66 I guess it's never to late to own a Colt! Is it a Webly or Eley .455 ? and How can I tell if it's been reworked to accept Colt 45 ammunition? As many details as I have are below. Any body know just what I have here? I think I have a 1914?? British .455 Colt New Service Revolver. Has some standard factory Colt proof marks along with British proof marks. Colt logo above the grips on the rear left side of frame, VP inside a triangle on the front left side of trigger guard, and a #3 on the rear of trigger guard same side. Has had the orig. barrel replaced with a stainless steel 8" smooth bore pinned barrel. British proof marks on 3 different places on the revolver. On the breech area, the rear of the cylinder, and inspection and acceptance markings On the left rear of the frame (just below the hammer). Broad arrow government acceptance mark on top. Under that is a Crown Under that is F9 E Bone grips that look like they are orig. also. A large #7 is stamped "under" the serial number at the crane too, and the grips are also marked with the #7 in pencil underneath on both grips. On the left side of the frame under the grips is stamped the capital letter "E", so I know originally it was chambered .455. Highly polished mirror like blue finish on the original frame. Has a lanyard swivel on the bottom of the frame and has "No markings, lettering or numbers on the frame"by the lanyard swivel. Any Help/Feedback is Greatly Appreciated Thanks in Advance!
