The Parkes telescope has receivers operating from 440 MHz to 24 GHz (I think). see http://www.parkes.atnf.csiro.au/obse.../pks_ug_3.html

or do you mean what are the limiting factors of the Parkes radiotelescope?

Google is you friend.

A re-phrase maybe ?

Hi Matthew,

Welcome to IIS. It doesn't seem many people are payng attention to your question but I think the problem is that you might need to re-word or re-phrase it after a little thought on you part.

Are you asking about its resolving power ie ability to "see" as seperate, increasingly close radio sources?

Are you talking about how faint the signal is before it is no longer detectable?

Are you asking about its limitations as to what part of the sky is visible?

Are you asking about what wavelengths are outside its ability to "hear".

What do you mean by "information"?

These are all seperate questions and I think you need to ask something more specific. Most of us here are amateur astronomers and (very) few of us are involved in radio astronomy.

Does this help:http://en.wikipedia.org/wiki/Parkes_radio_telescope

Or this:http://www.parkes.atnf.csiro.au/

Perhaps you might get a quicker answer from the ATNF of Parkes themselves because as I said, few (very few) of us are involved in radio astronomy and a very small number are professional radio astronomers.


Best,

Les D

+26 to -90 dec

Hi Matthew,

The minimum elevation above the horizon of the dish is 30.5 degrees.

As the observatory it is at 33 deg S latitude, the furthest north in declination it can look is about +26.5 deg.

So in the end in can see whe whole sky between -90 declination and +26 declination. Anything further north that about +26 degrees declination can't be examined.

Hope that helps,


Best,

I think if you expressed yourself a bit better and less abrupt you may get more information.
Otherwise try Google or wiki

The answer to this is the same as the answer to the old question "how long is a piece of string?"
It can look as far as there is bright enough radio sources to detect.
The ability to detect any source for any telescope is determined by the size of the scope and the sensitivity of the detector.
Parked is pretty big even for a radio telescope at 64m diameter and it has sensitive recievers.
As a simplistic measure it can take images of very distant galaxies.
