Astronomy every Thursday
Two absolutely fantastic images of the Moon at 0.01 phase taken by member Jim Burchell on the morning of the 25th August 2022 from Dartford. The second image shows the Moon with Venus on the right.
Our sun on the 22nd Aug 2022 imaged by member Simon Dawes. Despite seeing being very poor that morning; a great image was achieved by Simon showing an active sun. Details of how Simon acquired the images are on the main photo.

A superb image of the moon at 3.30am on the 20th Aug 2022. This is Neil's first waning crescent moon image of the moon at 40.9% & 33 days old.
Click on the link below; then sit back and enjoy a wonderful video compiled by member Neil Webster of a waning gibbous moon he imaged on this date last year coupled with some ambient based piano/synth music produced by Neil too.
Three CMHASD members imaged the full moon - the 4th and last supermoon of the year rising on the 11th August 2022 and below are their stunning photos.
A full moon occurs when the moon and sun are opposite each other and sunlight strikes the moon face-on.
The August full moon is also known as the Sturgeon Moon so this was a Sturgeon supermoon!
Nasa explain: 'The term 'supermoon' was coined in 1979 and is often used to describe what astronomers would call a perigean (pear-ih-jee-un) full moon: a full moon occurring near or at the time when the Moon is at the closest point in its orbit around Earth. Therefore the moon appears larger and brighter than usual as it reaches the full moon stop of its cycle. A supermoon will usually cast around 30 per cent more light onto Earth than it does when it is at its dimmest. This is because the supermoon will be closer to the sun's rays and therefore able to reflect more light.'
We have already witnessed three supermoons this year, in May, June and July. Surprisingly, supermoon streaks like the one we have seen this year are not uncommon. 2023 will also see four consecutive full supermoons, as will 2024. Even 2025 has three in a row.
Jim Burchell's full moon rising images below were all taken with a Pentax KP at 300mm, F7.1, 1/3s & iso 200.

On Saturday the 20th of August several members of the Society were present for the second of our 2 solar observing sessions at Hall Place & Gardens. The event took place on the patio with a small farmers market close to the gallery so there was a constant stream of people wanting to look, some just wondering what was going on and and others who clearly had an untapped interest in astronomy. Hopefully we will see some of those people in the future.
At our previous session at Hall Place on Sunday the 7th of August we and those who came to see us were treated to 4 hours of sunshine unfortunately on this occasion we were not so lucky with varying amounts of cloud being present throughout the session. When the clouds did clear and the sun became visible we were able to offer safe views of the sun to the public through the telescopes. When we did get glimpses of the Sun - the public were thrilled with what they saw; even if it was often in 20 second bursts!!!
Overall we had 7 telescopes on hand including 'Anita' one of the clubs Dobsonian telescopes and during clear spots every telescope was in use. We also had a couple of tables of displays including details of Sun spots, a solar projector and other interesting Astronomy facts which proved popular too with the public.
Whilst the weather was disappointing the day was a great success and the Society would like to thank all those members who helped on the day.
Below is a slideshow of photos taken of the day by members John Archer, Simon Dawes, Diane Clarke and Dr. Mike Rushton - Thank you for sharing them with us. Also thank you to Diane Clarke & Simon Dawes for your help writing this post.

Prior to going to the event member Simon Dawes took the opportunity to image the lone sunspot on the surface of the Sun at home and this is his image. This was the sunspot that the public would have seen through the telescopes during clear gaps in the cloud.
A word document that you can download detailing some useful astronomy apps and software has been uploaded to the New to Astronomy page. Thank you to member George Buckberry for compiling the list.
Sunday 7th August 2022 - What a glorious sunny day to be out Solar Observing which is what Crayford Manor House Astronomical Society Dartford (CMHASD) where doing at Hall Place in Bexley. What a busy day it was too! Several telescopes were set up to observe the Sun safely and members of the public were invited to do some solar observing which was readily accepted by many. The Sun put on a good display having several sunspots and prominences for the public to view.
CMHASD will be back at Hall Place on Saturday 20th August 2022 to do some more Solar Observing with the public. Please do come and join us!

Thank you to all CMHASD members who helped on the day and to Dr Mike Rushton and Terry Miles for sharing your photos of the day too.
Sit back, relax and enjoy the 3 wonderful videos below put together by member Neil Webster showcasing some of his stunning astroimages alongside some beautiful music created by Neil in his home studio.
