Date: April 6th 2020
I did chase the best exposure to see Venus' phase of course and it was 1/2000th second compared to 15 seconds I used for the image, so had to balance the photographic nature of the image with a useful astronomical image.  Looks won!. I could always cheat and use an old M45 image and lay Venus on it, but why bother.
Those pesky craterlets can be difficult.  I did see them in the 16 inch, but it took a few goes, and as I reported once that I could see Armstrong and Collins craters near the Apollo 11 landing site in the 20 inch, they are around the same size,  so should not be an issue.  I have imaged them in an 8 inch reflector a long time ago, but never visually saw them, so that does not count.  I have not looked for them in the 8 inch RC - yet.  15th April looks to be the next opportunity.  Given the reports you make with the 7 inch Mak I should think you have every chance to spot them.

Take care

Trevor

Nice image Trevor. No shadow bands then? Some of us are chasing craterlet's in Plato - sad, but passes the time and makes a pretty image!

Please add image to the web site, I'll send the original. The new email list has a strange comment with regards maximum file size:
 Venus visits M45 and its clear, but couldn't deliver it to the mailing list because the size of the message,  4976.1 kilobytes is larger than the maximum allowed 2621440 kilobytes.
 Let me know if you need any more details.  Herschel 400 is on hold as the 20 inch is on isolation which is a pity as this has been the best spring observing weather for a long while.  I was tempted to come and pick it up, but it breaks the rules at the moment.
As for CBS, not entirely sure, I think the correspondent is not a scientist, but they have interviewed an astrophysicist already and getting a hobbyist view of how things may have improved. To date there is little haze under the anticyclone we have just had - the source is from Europe at the moment and visibility has not reduced by particles, there are no condensation trails spreading Cirrus across the sky etc ., less moisture in the upper Troposphere and lower Stratosphere leading to better transparency.  It may all be down to weather of course, but a  nice outcome.  I'll try and promote switching off  streets lights as there is nobody about to make use of them 😉😉.
Are you working from home as well?

Regards

Trevor

From: ian@PROTECTED Nice picture Trevor, can I nick it for the website?

With regard to the nice weather, is this the idea that since planes have almost completely stopped flying and there’s so little traffic on the roads that the weather has gotten better? I would have thought that since we’re in the middle of spring we could expect to get some decent weather at this time of year. 

Anyway, could luck with the Messier marathon. How’s the Herschel 400 going?

Cheers,
Ian

I hope everyone is keeping well and sane in these trying times.  For myself and Cheryll, its business much as usual, but with the added interest and extra  time for some Astronomy.
The Messier marathon is still going and I have captured 55 thus far.  As mentioned the planet Venus visited M45 over the weekend and unusually a promised event was fully visible so attached is the image.  This was composed of 50 images but only 15 second exposures.  I could not really bring out any of the nebulosity from M45 without overdoing the planet.

Talking of clarity of skies, CBS News are planning to visit me on Tuesday to talk about the clarity of skies since the lockdown has happened.  Not sure how the 2 metre rule will apply, but I hope they can handle that side of things.  I'll let you know if anything comes of it.

Stay safe

Trevor

We also collect the names and some contact information for visitors to meetings that are prospective members. We collect these data directly from our members when they join the club or are prospective members attending their first meeting.

For some of our members we may have additional information such as committee memberships. For all members we maintain data on whether they have paid their AAS subscription.

How does AAS use these data? We use members’ data for the administration of your membership and communicating with members of concerning membership and our events.

Do we share your data with other organisations? AAS does not share your data with any other organisations.

If you register with aaslist email mailing list, the data you share with the list will be subject to this privacy policy. Membership of aaslist is optional and provides email discussions of astronomical topics and notices of meetings and events organised by AAS and others.

How do we collect your data? Data are collected from members when they join AAS and complete our subscription form. Data are collected from visitors when they enter their first meeting. Email addresses are also received via applications to join the aaslist list; although, in many cases, members will already have supplied this on joining AAS.

How is your data stored? Completed subscription forms are stored securely in the private homes of the AAS Treasurer and/or Secretary.

Members’ data in electronic form are stored on the personal computers of the AAS Treasurer and Secretary, which have Internet security and anti-virus measures in place. No data are stored remotely except the data provided to the optional aaslist mailing list, which is stored on the UK servers of fasthosts.co.uk and subject to their GDPR policy.

Who takes responsibility for ensuring data protection compliance? We do not have a statutory requirement under the GDPR (General Data Protection Regulations) to have a Data Protection Officer. The Committee of AAS is the Data Controller. The person who is responsible for ensuring that AAS discharges its GDPR responsibilities is the AAS Secretary.

You can contact us with a ‘subject access request’ if you would like us to provide you with any other information we hold about you.

There is not usually a fee for this, though we can charge a reasonable fee based on the administrative cost of providing the information if a request is manifestly unfounded or excessive, or for requests for further copies of the same information.

Can you ask AAS to remove, limit or correct the data held about you? You could maintain your club membership with your correct name but with limited contact details. AAS needs to have at least one method of contacting you. You could for example simply maintain an up-to-date email address.
