Coronado Maxscope 40 Solar Telescope

I have a Coronado MaxScope40 solar telescope with Ha and BF10 filters, T-Max filter Detuner  and CeMax eyepieces. For more details of my setup and accessories I have made or adapted - click image on the right

Venus Transit of Sun. 8th June 2004

We took the opportunity to host a Transit Party in our backyard and viewed the transit with 23 friends. A most enjoyable time was had by all with most opting for Bucks Fizz, a full English fried breakfast, toast and marmalade eaten outside!

Three telescopes were set up with white solar filters plus an H-alpha Maxscope 40 solar telescope and a binocular projection. Solar glasses were also available.

Great fun was had by all but with such a party and breakfasts to cook there is no time for much photography. The general comments from our guests were that they did not expect to be so enthralled with the event (i.e. schools, TV and press had not provided adequate information and enthusiasm) and how they were interested not only on the mechanics of the solar system but the history and human exploits surrounding the stories of Copernicus, Kepler, Galileo, Jeremiah Horrocks, Cook and others.

I managed to snatch two images with Canon G1 digital camera through the solar Maxscope 40 (note large prominence on first image).

Major Sunspots (0652) - 23rd July 2004

A large sunspot system was seen on the Sun in mid-July 2004. The following images were taken through the Maxscope 40 using a Canon G1 Digital camera  mounted on a 26mm eyepiece with a Scopetronix Digi-T adaptor.

I am still trying to understand how to capture and process the Ha images.

The images were processed using Paint Shop Pro 8.

Meade LPI Imager

I have used a Meade LPI imager with my Coronado H-alpha Maxscope 40 telescope.

The image of the Sun just fits the Meade LPI imager and first images through very hazy cloud cover look reasonable and worthy of some more effort on a clear day. The image has had to be compressed to get to an acceptable size for distribution over the web - be assured that the solar prominences on the original image are very good.

SOHO Observatory

SOHO, Solar & Heliospheric Observatory, is a joint European, American and Japanese satellite launched in 1995. SOHO provides an uninterrupted view of the Sun and has onboard a dozen instruments to measure the Sun's features and emissions across many frequencies.

Current images from several of the SOHO instruments are available online.

Books on the Sun

On bookstore shelves I find many books describing the individual Planets or the complete Solar System but not just the Sun.

One useful introduction I have discovered is Nearest Star by Leon Golub & Jay M Pasachoff. This book is easy-reading, requires no maths, and shows the development of our understanding of the processes and science within the Sun.

An Observer's Guide to the Sun by Pam Spence was published in 2004. This book provides a good introduction to both viewing the Sun and recording and analysing your observations. The book is attractively produced with many coloured diagrams. The shortcoming is in the area of 'snapping the sun' where only 35mm film is covered: ccd and webcam imaging should have been covered.
