This is John's first submission to the Deep Sky gallery, and what a great image.  He reports some issues with artefacts and also that this was his first attempt at combining LHaRGB and the calibration of the lights with flats, darks and dark flats. Warren A. Keller, author of Inside PixInsight was very helpful with questions on the "PixInsight for Beginners Group" on FaceBook.

Ron Brecher's presentation on The Astro Imaging Channel on YouTube helped with a dust mote that wasn’t entirely cleared by the master flat (Pixel Math section “if the pixels are this, do this, or do nothing”). Using this method helped him to slightly raise the brightness of pixels in the offending area leaving the rest of the image untouched.

The artefact? Well, as hard as John tried he couldn’t remove a light-ish smudge to the left of Messier 81, but checking on the Astrobin website showed that this was in fact galaxy PGC28757!

A beautiful evening arrangement of the crescent Moon with Venus and the Pleiades, further enhanced by the colours following sunset. With a prediction of a bright ISS pass, Pete grabbed his camera, composed the shot, guessed at the settings and went indoors, letting the remote shutter release do all the hard work.  He turned some internal lights on to provide reflection highlights on his scope which was set up to image the Moon.

The annual Sir Patrick Moore Prize of £500 plus a year's membership of the BAA may be awarded to any person, group, society or school (whether member/affiliate of the BAA or not) for one or more of the following areas of activity, selected to reflect Sir Patrick’s life and enthusiasms:

1. The encouragement of a public interest in astronomy

2. A contribution to the understanding of the history of astronomy

3. Outstanding observational work by a member or members under 21 years of age

4. The encouragement of participation in observational astronomy by youngsters

5. The carrying-out of a collaborative research project, whether between amateurs only, or also involving professional astronomers.

Last year’s prize was awarded to Dr Stephen Barrett (pictured right with President Alan Lorrain) for his work giving talks on astronomy to diverse groups of people all across the midlands and north of England.. 

Council is now inviting nominations for this year’s Prize. Nominees may be nominated by themselves or by another. Please send nominations, including a short statement explaining the reason the person should be considered for the awarding of the Prize, to Madelaine Davey at the Office (email office@britastro.org) by September 30. Nominations will be considered by a committee, which will make a recommendation to Council, and the Prize will be presented at the Christmas Meeting, if possible.

Nominations for the 2020 Ballot for the BAA Council and Board of Trustees

An election will be held in 2020 October for the Council of the Association and the Board of Trustees. A ballot list will be sent to members with the August Journal.

Under the constitution approved in 2015 May, the elected Council comprises the President, Treasurer, three Secretaries, plus five further members of the Association. Additionally, all Section Directors, Postholders, the elected Board members and the Vice-President (ex officio) are automatically members of the Council.

The Board of Trustees comprises the President, Vice-President, Business Secretary, Treasurer and five elected members, all of whom will also be Council members. You can stand for election to Council without being considered for the Board, but you cannot be elected to the Board without also becoming a member of Council.

If you would like to be nominated as a Trustee or a member of Council, you must be a paid-up member. Please ask two other paid-up members to propose and second you and then sign the letter or form yourself to show you are willing to stand. If you wish to nominate someone else, the same conditions apply. If standing as a Trustee, you must confirm that you have read and understood the responsibilities of the Trustees of a Charity as set out on the website of the Charities Commission and that you are prepared to accept and fulfil these responsibilities to the best of your ability.

All nominations must be in writing and sent to the BAA office to arrive by Sunday, 2020 May 10. You may use this nomination 2020 form if you wish. Signed and scanned forms or letters may be returned to the Business Secretary by e-mail to office@britastro.org or by post to:

Venus and Sky Notes videos

During these difficult times when many will be restricted to being at home, the BAA is developing a programme of videos and webinars to share with the world-wide astronomical community. We'll be posting news about these here (on our website), and on Facebook & Twitter - so please follow us on these channels for the latest.

The first of these are an excellent short video about Venus presented by John Mason, and Spring Sky Notes by Richard McKim.

These are both available on our YouTube channel, and you can also view them below.
