telescope image scale?

Question

what does the image scale of a telescope and what does it tell us?

Answer 1

I'm here, I'm here!

Hi!
Image scale is dependent on the focal length of your telescope, and the focal length of the eyepiece you are using at the time.
As I've said before, one night under absolutely pristine skies, I was able to max out my 10" SCT to about 700X while looking at Saturn.
The image was stunning, and the planet and her rings filled almost the entire field of view.
I hope this helps!
Clear Skies!

Answer 2

The size of the image that you see is dependent on the focal length of the scope and the eyepiece that is used. By dividing the focal length of the scope by the focal length of the eyepiece, you can obtain the magnification. So, if I have a telescope with a focal length of 2800 mm and I use a 28 mm eyepiece, I will see objects at 100X magnification, or 100 times the size that I would see them without using the scope at all.

Answer 3

seconds of an arc. How small an area can be divided.

Double stars are measured in seconds of an arc and a telescope that resolves smaller splits them in the view. You can't see them both together at the same time without dropping magnification.

Answer 4

You need to be more specific. Image scale usually applies in CCD imaging not visual work

Answer 6

It tells us a lot more than your question. Try again in plain English.
