I received a reflector telescope for Christmas, the clouds finally receded last night and I tried it out.
I can't bring the thing to focus though. The 'scope came with two eyepieces, a 10mm and 17mm "Super-Plössl". With either eyepiece in and, I presume, a star centred I only see the image of the secondary mirror struts highlighted against the primary.
I discovered that if I slide either eyepiece almost completely out of the drawtube (which is at full extension), I can get an image of the sky. I thought eyepieces sit completely in the drawtube though, not halfway or more out, grasped by the single fixing screw.
Is there something fundamentally wrong with the telescope? Does it just require collimation or somesuch?
Orion UK has a very good reputation so I'm surprised you are having a problem. However, I see they are offering this with a Crayford focuser. Most Crayfords have a lower profile than traditional rack and pinion types and they may have failed to realize this could effect back focus. If the scope is new I'd talk to them. If not, find a 2" long by 2" diameter focuser extension tube.
If it does have a traditional rack and pinion focuser it may be missing the extension tube. Many of this type have a threaded on extension tube which is used for visual work and removed for use with a 35mm camera. The solution's the same.

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.
Did you remove the lens cap? If the scope is like the picture in your question this is a REFLECTOR style telescope. It has a mirror in the bottom and a smaller secondary mirror under the focuser. The FOCUSER end is pointed UP. as in the picture above.
Can you focus on a distant object during the day time? Use the eyepiece with the largest number written on it and DO NOT USE the 2x barlow if you have one. Try focusing during the day time. If this works your telescope is OK. Then try the moon at night as your first target.
Notice they are on the end pointed UP. Do NOT use the 2 x barlow if you have one. Put the eyepiece with the largest number written on it into the focuser and practice focusing on a distant object during the day. The moon should be your first target at night.
That is a very simple reflector style telescope --- here is my suggestions-
1. Forget about the barlow--- since this scope has a very small aperture you will not be able to get much more than about 125 power-- if you try to use the barlow which DOUBLES or TRIPLES the power of your eyepieces the images you see will be degraded and it will be VERY hard to point the telescope and focus.
2. Put the eyepiece with the largest number (which is the lowest magnification) into the telescope and take it outside during the day and practice focusing on a distant object.
3. Take it out at night when the moon is up and LESS THAN 3/4 full-- the moon should be your first night target...... if all goes well try to find Saturn which is up in the sky right now, and appears as a slightly yellow "star".
4. The smaller telescope is the finder scope and mounts on top of the main telescope tube. Use this to point the main telescope------- but you must first line it up on a distant object so that the small telescope and the big tube are both pointed exactly alike.
5. Try to find a local astronomy club and attend one of their star parties.
6. Here is a manual for a telescope that is very similar to what you have except yours is on an Alt Az Mount while the one below is on an equatorial mount but many of the tube parts are the same--
There are only two types of telescopes --- REFRACTORS, and REFLECTORS-
The refractor has a lens on the front of the tube and you insert different eyepieces in the back-- the larger the number written on the eyepiece the LOWER the magnification-- (DO NOT USE THE 2x or 3x barlow which you may have!-- this creates too much power for this small telescope!-- put it away and never use it!)
A reflector has a main mirror on the bottom of the tube, and a small secondary mirror under the eyepiece hole (focuser end) - front end-- put the lowest power eyepiece into the focuser.
Now with either type telescope go out side during the day and practice focusing on a distant object-- turn the knob SLOWLY. At night the moon should be the first target you try.
If you received what appears to be a smaller telescope -- that is the finder scope-- attach it to the top of the tube on the main telescope. Again during the day line up the small finder scope with the main scope-- look at a distant telephone pole (the very top-- and center this in the main telescope. Without moving the main scope use the finder scopes "screws" to adjust the cross hairs so they are pointing exactly where the main scope is pointed. Now you can use the small finder scope to point the telescope in the exact direction--
