The Handbook of CCD Astronomy Book Review

The Handbook of CCD AstronomyThe Handbook of CCD Astronomy sounds a perfect title for an amateur to learn everything about how to use my Meade CCD camera with my telescope. Thing is, this is no book for the amateur astronomer, but really for the research astronomers, academics and professionals.

The book begins by telling you everything about CCDs including the manufacturing process, the various types of CCDs and how they work. There are also some interesting sections on CCD pixel size, pixel binning as well as flat fielding. The book covers some very in-depth CCD topics such as how to calculate read noise and gain, and signal to noise ratio.

The book contains a great deal of graphs, diagrams and mathematical equations, well over my head as an amateur astronomer, but I did find some parts of the book good for explaining certain things such as how CCDs work and about flat fields.

The chapters in the book are titled CCD manufacturing and operation, Characterisation of Charge-Coupled Devices, CCD imaging, Photometry and astrometry, Spectroscopy with CCDs and CCDs used in space and at short wavelengths.

The Handbook of CCD Astronomy ends with a CCD reading list, CCD manufacturers list and some basics of image displays and colour images.

Handbook of CCD Astronomy is available at Waterstones

Cheap Astro Stuff at AstroBoot

Just found the AstroBoot page on ScopesNSkies site last night, after seeing someone mention a cheap webcam in a forum.

Who knows what cheap astro goodies have already been snapped up. I did manage to spend about £25 on bits and bobs, then went back this morning and spent another £10.

The funny thing is I only live a few miles away from ScopesNSkies, but am too lazy to venture out, plus the petrol costs would be about the same as the £1.50 P&P, even though I made sure I bought at least 3 items to get free p&p.

Venture over to AstroBoot now!

Moon and Venus

What great weather we have been having lately, could it be anything to do with there being no planes flying at the moment due to the icelandic volcano erruptions? After spending the day listening to talks, looking at telescopes and viewing trade stands at Kelling Heath I decided to come home and do some imaging.

The moon has been looking amazing at the moment in the blue twilight sky, unfortunately for me at the moment my west viewpoint is obstructed by my own house, so I snuck around the side of the house and managed to get this image below of the moon and venus on the bottom right.
