Please Need Help about 114mm Reflecting telescope
I am new using Telescope. I just bought a 114mm Aperture Reflecting
telescope from ebay. I couldn't make it work. After removing the eyepiece from the tube if i look down, i can only see reflection of my eye. Can anybody tell me is it normal, else how to solve it. Thanks in advance. dUKE |

Duke, I notice that you didn't get much help with your question. You do
not give any details of the scope, so I am assuming that it is Newtonian reflector. That's the kind with the eyepiece at the "front" end on the side of the tube. I went through the same process last year when I got out my late father-in-law's 1930's vintage homebuilt Newtonian. Maybe you could give us the make and model number of the scope. Anyway, here's what I did and recommend you do: Take the scope out in the day and find a prominent object (such as a distant water tower) as far away as practical. Use as big an object as you can. Take the cover off the end of the scope and put the eyepiece in it's holder (focuser) on the side. If you have more than one eyepiece, use the one that gives the least magnification. That would be the one with the "most" millimeters. G Be sure not to look at the sun or let the scope point at the sun during this process! If the scope has an sighting scope use that to find the object. Otherwise just sight down the main tube and work with it until you find the object in the eyepiece. Remember that you will need to focus the eyepiece to see anything, even in the day. Once you have the object in the eyepiece go back to your finder scope and use the adjustments to center the object in that. Note that the object will be upside down in your main scope (and probably in your finder scope) but the right-left movements will be normal. That takes a bit of getting used to and looking in the day will help you get the hang of it. Once you have figured out how the scope works in the day, you should be ready for a bright object at night. The moon is a good place to start but it is not readily visible for a few days. Jupiter is the brightest "star" in the sky and can be easily viewed in the twilight and darkness. Go out around 9:00 to 9:30 p.m. (I'm assuming you're in the U.S.) and look south southwest. It should be around 35 degrees above the horizon. Center it in your finder scope and it should be in your main scope. My guess is that you will see the planet and it's 4 moons in the main scope. Hope this helps. -John Finally "duke" wrote in message oups.com... I am new using Telescope. I just bought a 114mm Aperture Reflecting telescope from ebay. |

Others give some good advice here, but I can see that part of your question is not answered: "After removing the eyepiece from the tube if i look down, i can only see reflection of my eye." Yes, this is normal. In fact, collimating the mirror (http://skyandtelescope.com/howto/sco...icle_787_1.asp) requires that you don't use the eyepiece. More than likely, when you're trying to use the telescope, you're just missing your target. Using the lowest magnification eyepiece on an obvious terrestrial target will go a long ways to helping you line up your finderscope properly, as they are usually not perfect right out of the box. Also, using it during the day allows you to familiarize yourself with how it works. Once you've got a handle on that, give the Moon a try, and then Jupiter. |

I am new using Telescope. I just bought a 114mm Aperture Reflecting
telescope from ebay. Hi Duke, 114 mm (4.5 inches) is pretty small for a reflecting telescope. Can you post the eBay auction number? I'm just curious what the scope looks like. And yes, it's normal to see your eye when you remove the eyepiece. -Florian |
