Anyone that could help - greatly appreciated!

LOL Matt, 4 four more levels of shade won't make much of a difference at all !!

A 14 bit A/D converter gives you 14 bits per channel (RGB channel) shades of grey.

Ian is correct in what he posted but he means levels not 'bits', so a difference of 12288 levels.

Technically 14-bit A/D conv, means the camera records up to 16,384 grey shades per channel and allows the camera to record images with better and more accurate gradations of tones and colours.
What this means is basically you have a wider dynamic range to play with and ability to stretch the data.

Whether it will make a difference in your astro images in the end basically depends on your skills in processing and the ability of your monitor and printer to display the difference but 14 bits will give you a wider dynamic range to manipulate the data that's for sure.
