This month's Focus looks at CCD astronomy. Astrophotography is a major part of amateur astronomy now, with the advent of the revolutionary charge-coupled device (CCD) over two decades ago bringing high-resolution digital imaging to the fingertips of observers in their back gardens. In our Focus this month, Nik Szymanek kicks things off with an introduction to CCDS – what they are, how they work and the various options on hand to the discerning astrophotographer. Next up, Astronomy Now’s Equipment Consultant Steve Ringwood looks at the essential accessories required to get the best out of your CCD imaging set-up. Astro-imager Olly Penrice gives guidance on choosing a target and planning your imaging project, and finally Nik Szymanek returns with advice on image reduction and basic digital processing of your astrophotographs.
