Members' Images

 

Our members' methods of making observations range from simply looking up at the sky to using quite sophisticated equipment. Many of them record their observations, either with cameras or by drawing what they have seen, and many images have been published by national magazines and on national and international websites. Here is a small selection.

If you are inspired to creates some images of your own, or if you already have some that you would like to share with us, we would be happy for you to contact us.

Please send your images - and your comments - to web-at-ldas.org.uk (Replace "-at-" with "@")

The Sun

Safety note : NEVER look at the sun without using proper eye protection - This can cause serious damage to your eyes and even blindness.

The whole sun, showing sunspot groups

Sunspots follow an 11-year cycle, building up numbers to a maximum and then they become fewer until there are none visible at the solar minimum.

Although we are now past tha latest minimum, hardly any sunspots have been seen, which has caused debate among astronomers as to why this is so.

This was seen by Jerry Stone and others during a Public Astronomy Session in Hitchin town centre. Jerry reported that it was the largest prominence he had directly seen.

This amazing view of Mars rivals those made by professional astronomers just a few years ago.

A staggering view of Saturn, not taken from the Hubble Space Telescope, but by Simon Kidd from his back garden in Welwyn!

For a short time, Jupiter and Neptune were close enough in the sky to be seen in the same field of view in a tlesecope. Dale captured this amazingly rare event.
