Hey rog, just out of interest what your estimate of the faintest star recoreded in that image? got to be pretty low I would think.

Rog: No problem. When someone asks, it's a reflex reaction to find out. It's a sickness, really. :?

Ant: The blue plates reference is really just a table of photometric data. I plug it into a program that's centered on a star field and it plots the stars and I have to click on them to find their magnitudes. The program is freeware called Cartes du Ciel and has been mentioned before in another thread. You can also check the red plates, do a subtraction and get some limited color info for stars down to ~Mv=20. It's a fantastic program that I use all the time.
