CCD's and Twilight Sky.

Hello all,

I will appreciate your feedback on imaging astronomical objects in the
twilight sky.

This information will help in determining the CONTRAST required between the
astronomical object and the twilight sky and the required QE, Plate Scale
and other performance parameters of the CCD-Telescope system. We are looking
into "point" and "extended" sources and hence the optical dynamics of each
would be different.

Recommendations for CCD camera, Telescopic Optics and the strengths and
challenges of each choice would help many of us who are trying to
determining the faintest star/planet/nebula/moon that would be visible in
the twilight sky, at a particular time after sunset and at a particular
altitude and azimuth difference from the Sun.

Thanks for your responses.
Clear Skies to all.

Mohib.
