  1. This week we are joined by Stefan Berg the creator and maintainer of N.I.N.A - Nighttime Imaging 'N' Astronomy - a free, open source, astrophotography imaging suite that's been getting a lot of attention and interest recently. It is a software designed for all deep sky object imagers. Whether you're new to the world of DSO imaging or an experienced veteran, this project's goal is to make your image capture easier, faster, and more convenient. You can find our more information and download N.I.N.A from here: https://nighttime-imaging.eu/ Stefan will be giving us an introduction and overview of the software Meeting details below: Topic: EP17 - Sunday, 30th August 2020 7:30pm BST - An overview of N.I.N.A. - Nighttime Imaging 'N' Astronomy by Stefan Berg Time: Aug 30, 2020 07:30 PM London Join Zoom Meeting https://zoom.us/j/94026841093?pwd=allHblhuY25DUU1sWVBobm1yNUZEZz09 Meeting ID: 940 2684 1093 Passcode: 979003
  2. Just a reminder that this talk is on later today at 7:30
  3. This week we are joined by Anastasia Kokori the co-ordinator of the ARIEL ExoClock project and the project manager for the ExoWorlds Spies project. Anastasia will be giving us a talk titled: ARIEL and ExoClock: the future of exoplanets and how the public can get involved Anastasia is also the Astrographic Officer at Greenwich Royal Observatory and also a planetary scientist in training at Birkbeck University of London. She is a graduate of the Space Studies Program (SSP) 2018, organised by the International Space University (ISU), and also holds an MSc in Science Communication from Dublin City University (DCU), and a Primary Education Degree from the Aristotle University of Thessaloniki. She has a long experience in observing with small ground-based telescopes and also organising projects and events that involve the public and school students. Talk Synopsis: ARIEL is a space mission led by the European Space Agency, planned to launch in 2028. It will be the first dedicated mission to measure the chemical composition of many exoplanets. The main objective of ARIEL is to study in detail a large diverse sample of exoplanets orbiting different types of stars. The key science questions ARIEL will address are: • What are exoplanets made of? 
 • How do planets and planetary systems form? 
 • How do planets and their atmospheres evolve over time? 
 Understanding worlds beyond the Earth is a key issue for humanity and it concerns everyone, not only the scientific communities. We strongly believe that research and science is an effort that everyone can take part in. ARIEL will observe around 1000 transiting exoplanets and for this survey to be as efficient as possible, we need to have a good knowledge of the expected transit time of the planets observed. This is where small and medium-scale telescopes can contribute significantly. To better organise this effort, we have created the project ExoClock that is open to everyone, professional and amateur astronomers as well as members of the public can get involved and contribute to the mission. In this presentation we will outline the current status on exoplanets, followed by the key points of the ARIEL mission and how the ExoClock project is contributing. Meeting details below: Topic: EP16 - Sunday, 23rd August 2020 7:30pm BST - ARIEL and ExoClock by Anastasia Kokori Time: Aug 23, 2020 07:30 PM London Join Zoom Meeting https://zoom.us/j/93663661099?pwd=aU9qR0lRNEJhdzJYZW55V29OOHM4UT09 Meeting ID: 936 6366 1099 Passcode: 032530
  4. That's odd - I just checked and 1080P is an option? Perhaps try on a different device or, it can sometimes take YouTube longer to process the HD version so maybe it wasn't available when you tried?
  5. Hi Andrew - we are still using SGP, we tested Voyager but I didn't like some of the ways it worked vs SGP so have stuck with that. There are similar limits in SGP, you just have to set them (d'oh!). I'm now imaging multiple targets a night to ensure we get the target at it's best / highest.
  6. Excellent Dave - great to see a totally different spin on it!
  7. I've made a tweak on the server which will force your browser to download these rather than try and open them.
  8. Try right clicking the fits link and the a save as - sounds like your browser is trying to open it as a txt file rather than downloading it. I will look tomorrow, I should be able to do something to force download the fits files.
  9. Dave's StarGaZine video is here for you to follow along
  10. Data released so you can follow along Thanks to Dave @ Pixel Skies for a super talk!
  11. We got there in the end - M16 data now released. We have a whole load of Crescent data ready to release in a few weeks and then hopefully, within a few weeks of that M17 and then next up, IC59 / IC63. Accepting suggestions for next targets after that
  12. We've just released the first set of data from the Ikarus Observatory project here. To celebrate, we are running a processing competition to see who can get the most from this data and create the 'best' image! The winner will receive £150 of First Light Optics gift vouchers and two runners up will receive £50 of gift vouchers. Details below: Closing date: 4th September 2020 @ 22:00 Please post your entries into this thread Please only use the data we've released - don't blend it with other data or add to it with other sources Use what ever processing software and techniques you like, potential bonus points for sharing your workflow and techniques with others - that way, we all get to learn as well Multiple entries are allowed but, please refrain form posting multiple attempts that are very similar - better to update an earlier attempt if it's just an incremental improvement but, it would be interesting to see totally different attempts using different narrowband blends etc... If you win or are a runner up, we would really like to use your creation in future marketing materials, on our website etc.. so by entering the competition, you are giving us permission to use your image in this way. Judging will be done by a small team of judges from the FLO team - It's completely subjective but will be based on what image(s) we think do the best job of extracting the most from the data released and, look the 'prettiest' We will announce the winners by the 11th September 2020 via SGL Thanks all and look forward to seeing your attempts
  13. Following the excellent talk last night by Dave @ Pixel Skies showing his process workflow for our M16 data I'm please to announce the first public release of the data Some small print first though: We will be releasing all public data from the Ikarus Observatory project under a Creative Commons Attribution-NonCommercial licence. What this means is you are free to share, copy and redistribute the data as you see fit and adapt, remix, transform and build upon it but you must attribute 'Ikarus Observatory' as the source of the original data and must not use it for commercial purposes - i.e. no sticking images on the side of mugs and selling then Beyond that, enjoy and have fun! You can find out more about the IKO project here including details of the equipment used, observatory site etc.. We've done a few other test runs up to this point and have some more data awaiting release but we are starting with SHO Narrowband M16 data taken a couple of months ago. This started off as 100 hours in total but has been whittled down to select just the best frames - this is partly some learning on my part as I need to adjust the times we finish imaging runs to ensure it's within astro dark and the targets are high enough to get the best data. We've also cut out anything with any cloud passing through, issues caused by moon light, severe satellite trails and the like. This has left: Ha - 46 x 20 mins = 15h20m OIII - 29 x 20 mins = 9h:40m SII - 44 x 20 mins = 14h40m Bias 101x Flats 21x for each filter Darks 21x 20 mins Total integration time = 39h:40m These have been stacked and calibrated in Pixinsight. The raw XISF or FITS files can be downloaded here. Dave has also kindly shared his Pixinsight workspace with notes / icons / masks ready for you to play with, that's available here: iko_m16_20200817.zip but be warned, it's a rather large 3.8GB! Details of the processing competition are here. I hope you enjoy playing with the data and we look forwards to sharing more very soon!
  14. If you would like to watch this, Chris has asked us to keep the video private so please PM me and I can make it available to you for a short period.
  15. This week is something a little bit different - to coincide with the first public release of data from the Ikarus Observatory project we are pleased to be joined by David Wills of Pixel Skies which is where the Ikarus Observatory is remotely hosted. Dave is an expert astrophotographer, you can see some of his work here and has had several of his images published in magazines such as Astronomy now and BBC’s Sky at Night and various AAPOD’s. He will be taking us through a full work-flow in Pixinsight using around 100 hours of Narrowband (Ha, OII and SII) data taken of M16 from the Ikarus Observatory setup. This will start from the raw data that is being released which will already have been stacked and calibrated ready for processing. This won't be a full Pixinsight workshop as that's too much to cover in one session but, it will give you a tour of what Pixinsight can do and how you can put a workflow together. As the data will also be provided afterwards you will be able to follow along on YouTube yourself and have a go at following Dave's process or tweaking it to see what results you can achieve. We will also be announcing an image processing competition whereby we will be picking a winner of our favourite processed version I will also be giving an update on progress with the Ikarus Observatory project and an overview of what it's all about and how SGL members can get involved. Meeting details below: Topic: EP15 - Sunday, 16th August 2020 7:30pm BST - Ikarus Observatory Public Data Pixinsight Workshop by David Wills - Pixel Skies Time: Aug 16, 2020 07:30 PM London Join Zoom Meeting https://zoom.us/j/95946328998?pwd=a2E4bU1OWWEyL0JNTTRKYVVORDM3Zz09 Meeting ID: 959 4632 8998 Passcode: 908939
  16. Chris Lintott joins us tonight in around two hours - hope to see you all there
  17. This Sunday we have the absolute pleasure of being joined by Chris Lintott! We are very excited about this and Chris wants to give a talk a bit different to the norm which should be a great fit for us: 'The short long history of citizen science in astronomy'. I think you will agree, there is no one more qualified to talk about citizen science and astronomy Chris is a professor of astrophysics at the University of Oxford, where he is also a research fellow at New College, working on topics from galaxy evolution, transient detection and machine learning. As Principal Investigator of the Zooniverse, he leads a team who run the world’s most successful citizen science projects, allowing more than a million people to discover planets, transcribe ancient papyri or explore the Serengeti. A passionate advocate of the public understanding of science, he is best known as co-presenter of the BBC’s long running Sky at Night program. His book, ‘The Crowd and the Cosmos’, is now available from Oxford University Press. ‘Citizen Science’, through projects like Galaxy Zoo and Planet Hunters which ask volunteers to sort through data, is more popular and productive than ever before. But amateur astronomers have been making contributions to science for centuries. In this talk, which will include stories of a p**ed-off Welshman, a stoical Prussian and at least one story about penguins, Galaxy Zoo founder Chris Lintott (BBC Sky at Night) will talk about the historical foundations of citizen science, what can be done now - and what opportunities will exist in the future.

  18. Your old account is still there and active, perhaps you forgot the password? If so, just use the password reset link on the login page - there is no technical reason your old account won’t work.
  19. Just in time for the beta release of APP with the new comet features: https://www.astropixelprocessor.com/
  20. Trying something different this week We are going to be hosting an astro Q&A session with many of the SGL mod and admin team on the panel ready to (try!) and answer any astronomy questions you may have. Expect tangents, potentially demos and some head scratching If you have a question or subject matter you would like us to touch on you can let us know in advance or ask us during the meeting live. We don't know how this will work out, it's a bit of an experiment so please bear with us and let's see how it goes.
