Astrochemistry as a subject has been rapidly evolving in recent years driven by theory and experimental results. It is a subject that encompasses chemistry, physics, astronomy and biology, and can be thought of as moving from the chemical make up of other atmospheres and space itself, through to the formation of organic life in the universe. It has moved very much from a subject portrayed in science fiction films to hard science. From a teaching point of view, it has the advantage of combining key elements of chemistry with physics and biology in an interesting and stimulating subject, much more appealing to the students than more traditional chemistry subjects. It could become the 'atmospheric chemistry' course of tomorrow.
Astrochemistry is a basic introduction to the chemistry and physics of atmospheres other than Earth's. It is based osecond year chemistry course and assumes some knowledge of physical and organic chemistry along with some basic physics. Little prior knowledge of biology or astrophysics is assumed. Starting with an introduction to the chemical universe, the text covers stellar, meteorite, comet and planetary chemistry, before covering prebiotic chemistry and life in the solar system. Results from the latest research have been included throughout.

n the last few years, cheap webcams have revolutionized amateur astronomy by providing a very inexpensive alternative to purpose-made astronomical CCD cameras, which use refrigerated imaging chips and are thus extremely expensive. Webcams are capable of more advanced work than 'normal' digital cameras because their simple construction makes it easy to remove the webcam's lens, allowing it to be interfaced directly to a telescope. Using a webcam is not difficult but most amateur astronomers who have tried to do this do not achieve the finest results, despite the webcam's potential. There are numerous imaging and image processing tricks and techniques, and all of them are needed to get the best results.Along with webcam technology has come simple-to-use image processing and enhancement using a PC: the most powerful technique is, 'stacking' in which the best images (out of hundreds) are selected and summed automatically to provide startlingly good results."Lunar and Planetary Webcam Userв_Ts Guide" de-mystifies the jargon of webcams and computer processing, and provides detailed hints and tips for imaging the Sun, Moon and planets with a webcam. He looks at each observing target separately, describing and explaining all specialised techniques in context.Glance through the images in this book to see just how much you can в_" easily в_" achieve by using a webcam with your telescope!

The night sky holds endless fascination for anyone who chooses simply to look up and observe, but with so much to see, it can be difficult to know where to start. This remarkable book introduces you to the fifty best sights in astronomy and tells you exactly how to see them. In no time at all, you will learn how to find and appreciate the Orion group of constellations; the Summer Triangle; Venus, Jupiter, and Mars; the best meteor showers; man-made satellites; star clusters; novae; variable stars; and more. Once you start gazing, you'll see that the sky really is the limit—and discovering its amazing treasures will become your lifetime passion.
The sights are presented according to the field of view necessary to see them. Your eyes and a clear night sky are all you need to view the sights in the first part of the book, before moving on to those that can be observed through binoculars and, finally, a telescope. Concise descriptions and explanations of these spectacular visual wonders will deepen your appreciation of them and spur further exploration. You will also find the essential basic information on astronomical observation you need to get started, including observing conditions, techniques, telescopes, and astronomical measurements.

The book will, in jargon-free blow-by-blow terms, describe how to create the best astronomical images you can with the digital camera equipment at your disposal. It will explain the steps we go through to extract results from the raw-and-dirty original imagery, and then transform them into high quality pictures that you could hang on your wall.
The advent of CCDs, and more recently inexpensive webcams, has led to a much greater proportion of amateur astronomers becoming involved in digital imaging. The low price of the new Meade Deep Sky Imager - $299 (2005) – suggests that within a few years a simple digital camera will become a standard accessory for any telescope.
There are as yet few books available on this aspect of amateur astronomy. This situation is likely to change in the next few years and there are going to be lots of people out there asking questions like "Flat field? What does that mean?", and trying to work out how to get the best out of their webcam, CCD or Digital SLR. They will also be wondering what is the best software to use.
To summarise; this is a book that tells practical astronomers (and that includes some but not all professionals) what is needed to get from standing in the dark with a telescope and a camera, to showing your spouse, local society friends or even supervisor the astonishing images that can be obtained with simple equipment but the right software and knowledge of how to use it.

Of all the fixed stars in the night sky, Sirius is by far the brightest – almost twice as bright as its nearest rival, the star Canopus, which lies too far south to be viewed from most of the Northern Hemisphere. Only the Sun, Moon and the planets Venus, Jupiter and, at times, Mars, appear brighter. Sirius, with its flashing brilliance, is a striking feature of the northern winter sky and has understandably drawn the attention of observers of the night sky for thousands of years.
Sirius has many names. Astronomers recognize over fifty designations for the star, but the most commonly used is Alpha Canis Majoris, the brightest star in the constellation Canis Major. This is Latin for the 'Great Dog', which has led to its popular nickname the ‘Dog Star’. Over the centuries many beliefs have come to be associated with Sirius. Some of these beliefs still echo in such phrases as ‘the dog days of summer’, which the ancient Romans understood well. Other old beliefs long ago fell from public consciousness — only to be revived and to grow into modern popular and scientific controversies. Although these beliefs may seem quite recent, many have their origins in the ancient lore surrounding Sirius; humans seem naturally drawn to its brilliance, and a surprising number of modern cults have nucleated around beliefs in which Sirius plays a prominent role.
