Sad news indeed – the passing of a giant.
It was Maurice’s pioneering CCD work in the 90s that encouraged me to start CCD imaging.
Jeremy
Excellent Sky Notes Nick – well worth watching. Sorry I missed the live version of your talk in London yesterday.
Your Sony A7 camera is certainly yielding wonderful results!
Jeremy
Gosh, was it as long ago as that Robin?
Good to see you are still following it even though it’s so faint.
Jeremy
Thanks Alex – certainly looks like the same event.
Sorry to hear about your travel woes, Bill. I had some delay too, but at least it was a splendid day at the Newcastle meeting. Excellent talks and good to meet up with folks, including you and Alex.
Jeremy
>>It turns out the whole fleet has appropriate names for our community
I hope you are not referring to “Monsoon”, James?!
But, yes, indeed there are some most appropriate names.
All the best,
Jeremy
I’ve just uploaded an image of a nice double-peaker to my Members Page
Thanks for sharing the link to Steve Shore’s explanation – it’s a really interesting read.
And congrats on getting the timely spectrum!
Go well!
JeremyThat’s a great animation, Dave! And you were so lucky to have it passing close to the AR.
Are you able to make a composite image showing the ISS in transit?
All the best,
Jeremy
Great image, Gary. Nice to see some activity on the Sun!!
I was looking to see if you had any more images on the BAA Members’ Pages, but couldn’t find them – it would be great of you could start your own members page.
All the best,
Jeremy
Hello Edward,
if you type “hyperstar” into the Search box towards the top right of the page you will find some images taken with the hyperstar.
All the best,
Jeremy
Hello Ian and welcome to the BAA!
There are quite a few members who enjoy observing double stars. The Deep Sky Section’s John McCue is the DSS Double Star Adviser. He has written a tutorial on the measurement of double stars on the website. John has written another article on double stars here.
Nick White has written and article on the technique with which he observes double stars in the 2017 April edition of the Journal which you can read here (to read the whole article you need to be logged into the BAA website).
There are also some members who use lunar occultations to detect very close double stars (there are two dips in brightness as each component is occulted). An example by Alex Pratt is shown on his Members Page.
These are only a few examples of double star activity within the BAA. You mention there is quite a bit on our website, so do enjoy looking around. You might be interested in this article by Callum Potter about colourful double stars of the summer (which I hope will soon be here!).
All the best,
Jeremy
This article in today’s Independent talks about the impact of white LEDs on human health.
Dr Mario Motta, amateur astronomer and member of the American Medical Association, will be talking about this emerging problem during the BAA summer meeting (during the Sunday session).
Jeremy
Many thanks for the update on this fascinating piece of work, Alex. Do keep us posted on what Bruno Sicardy finds out about the atmosphere.
Jeremy
There is some more discussion on condensation here.
Jeremy
possibly, Grant. But the corrector plate is obviously still exposed as it looks out of the dome slit.
Jeremy
Grant,
I use a standard dew heater band on my C11, near the corrector plate. I used to have a dew shield as well, but it was a pain as I kept dislodging it as I moved around the obsy. Moreover, if I needed to cap the telescope during breaks in observing, or to produce CCD dark frames, I had to take the shield off, put the cap on and then reverse the operation to start observing again. Too much of a hassle!
I look forward to seeing your results with the RASA.
Jeremy
I too got an Atlas Coeli in around 1977. My father had to arrange some kind of bank transfer to order it from the US. I owned it into the 90’s, but then gave it to someone else. I never had the negatives. I recall there were desk and field editions of the atlas available. I still have the catalogue, but I’m not sure I ever used it in earnest!
Let us know what you turn up, Tony.
Jeremy
