The telescope also comes with a couple of lenses;
Super 25 wide angle Long Eye Relief
Super 10mm
Barlow Lens
What does each lens do?
Plus it has a small mechanical box which has Simple Type EQ1 Precision DC Motor Drive.
How this works I have no idea (yet), help me if you can.
I have the original manual and while it tries to help me work it out it is a little hard to know if I have actually set it up correctly or not... it looks like it is but is it, how can I tell?
I really have no idea of how to balance etc so I am asking is there an idiots guide to setting up the telescope.
Cheers for any and all of your help, advice and suggestions. |
Welcome. I hope you enjoy your new scope. I don't know that specific scope but I assume it is a small refractor ~60 to 90mm in diameter.
The different eyepieces are for different magnification. Magnification is worked out by dividing the focal length of the scope by the focal length of the eyepiece. The scope focal lenght will be written on the front of the lens. Something like 600mm.
The 25mm eyepiece will be the easiest to use. It gives less magnification but this is OK. Small scopes don't cope well with high magnification and you just magnify the blur if you use higher magnification.
The barlow usually acts to halve the focal length of the eyepiece. Using it with the 25 mm is like using a 12.5mm eyepiece thus doubling the magnification. You will use it rarely.
The mount has 2 axis and will have little levers that act as locks to allow the mount to freely move around the 2 axis when released.
Put the scope on its tripod and aim the long axis of the mount at the south celestial pole. This is due south and at a height that is equal to your latitude. I live 30deg south so the pole is 30deg from the horizon due south. For a first attempt this only needs to be relatively roughly aimed.
Put the scope on the mount and release the clutches 1 at a time. Move the counterweight until the scope will balance itself reasonably well in both directions. You may need to slide the scope in its rings to balance it.
This can all be done in daylight (DO NOT AIM IT AT THE SUN AT ALL). Connect the finder scope (the little telescope that attaches to the main one). Put the 25mm eyepiece in the scope and aim it at a distant tree or pole. Then look through the finderscope. There should be a way of adjusting the finder scope to aim it at the same thing that you can see through the main scope. Once this is done, leave it attached to the scope.
You are then ready to try it at night. Try aiming at the moon first and focus it. Currently the moon is nearly full. Just near it is Jupiter and this will look good as well.
Good luck
. If you're really stuck, one of my work posts is in Collie. My postings are Collie, Perth and from next year Karratha so if you're really struggling, I might be able to drop down your way in the next week and a half after work.
Greg you should ring him up anyway it will be a great learning curve for you and your son to have someone there to get you going without the frustrations 
. We've all been there and I'm glad to offer help where I can.
