First, how the heck do you aim one of these things accurately at a little
dot in the sky and keep it still long enough to see anything?
|
I don’t have an answer here. I hardly use telescopes; I’ve used my father’s
once or twice, but it’s on a stand.
| |
When I use the different lenses, I think that the lower the number the
higher the magnification. Is this right, or is it the other way around? I
wear glasses; should I take them off to focus an image in? Are the focus
settings similar for each different lens, or will I need to exend the lens
tube farther and farther for each lens? Should I move the actual telescope
tube itself, and refrain from touching the lens tube?
|
I don’t know about the movements of the telescope, but about the lenses. If the
lenses are similar to a microscope’s (I’ve learned about microscopes last year
in school, which was torture, but I did good), the higher the number, the more
magnified. If the base lens is say, 10, and the objectives are 100, you
multiply 10*100 to get 1000X magnifiction.
| |
Do I need a special camera adapter to take pictures of any images I’m
lucky enough to get? I understand that the images are upside down and
flip-flopped, but believe that to be correctable with image-editing software
(or a very expensive (IMHO) correcting lens.

No comment on this.

Please share your experiences and advice with this poor lost skywatching
soul. Any help you can provide will be much appreciated. Thanks!!!

| Greetings, fellow .Spacers! A few years ago I went to Target and bought a little telescope from the toy section: a Discovery Channel telescope, 300 power, 50 mm; I forget the actual manufacturer's name, but it was a real telescope company, and this (...) (21 years ago, 16-Aug-03, to lugnet.space)
