Observing The Moon Book Review

Observing The Moon BookObserving the Moon is a hardback book from Cambridge University Press by Gerald North. This is the second edition of the book. When I started reading the book I was thinking that it was going to be a boring book just about the moon, but how wrong I actually was. It does contain a lot more information, including information on how to image the moon, via a webcam and video camera.

The book begins by describing the moon, its phases, eclipses, gravity and tides as well as occultations. The book then discusses what sort of telescope you need to best view the moon, as well as buying advice and eyepiece types and what you may need if you want to do some moon drawings.

Observing the Moon then goes through what you need to image the moon, this is a great section, if a little dated in areas. The book mentions CCD cameras, DSLR cameras, video cameras and image processing – including stacking your moon images using Registax.

Observing the Moon also covers each area of the moon with descriptions, photographs and some drawings. I must admit when reading the book it was the first time I had ever seen a really good image of the far side of the moon, it had me mesmerised.

The appendices cover telescope collimation, field testing a telescope’s optics and how to polar align. The books images and drawings are all in black and white, but when discussing the moon this does not really matter.

Overall a great read, and please don’t think this book is just about the moon, as there is so much more in it, such as telescope buying advice and how to image the moon.

Observing the Moon is available at Waterstones

Latest Sunspots 1092 and 1093

After several days of cloud and rain, the clouds parted and I managed to get a shot of the current sun with its sunspots.

These are recorded as sunspots 1092 and 1093 from left to right.

This is not a great image, as it’s a bit blurred. Taken with my homemade DSLR solar filter on my camera using my 300mm lens.
