The lecture on technical challenges of measurement in astronomy went well and loads of interesting questions. All started from the slow (15years) of looking for exoplanets round V470 Cam. Easily visible reduction in the errors over the time I have been making measurements. Some of the error reduction techniques I have used.

Delivered to a great audience at the Farnborough Site (Cody AS). Mix of history, science, technical information and current research. Need to put it on Astrospeakers.org Now loaded on arXiv.org Cornell University Archive.
Living just south of Gatwick Airport in a dark sky area still has some challenges.   Astroart 8.0 is now available from the MSB-Astroart.com Many improvements and better accuracy in some functions. All major cameras, telescopes, filter wheels and focusers are supported by Astroart. Updated plugins are released for free. Astroart is also an open system with plug-ins and development kit for C++, C#, Pascal, Visual Basic. Fully compatible from Windows 10 to Windows XP. Compatible with WINE for image processing. Now being used in Woodland Observatory. I have missed another night of binary star measurement due to interference from Starlink. So much space pollution being caused deliberately by Elon Musk. My research could become more difficult as it will for anyone wanting to look beyond the earth. Over 11000 satellites to be launched…your joking, We only have a small percentage so far.. It wrecked my measurement of distant binary systems last night..  https://phys.org/news/2020-05-costly-collateral-elonmusk-starlink-satellite.html This is one of my favourite galaxies. Just did a quick exposure after doing some adjustments on my telescope.  Nice plot of the light curve for HS0705+6700, 2.3hr, post-common envelope eclipsing binary system. Spectroscopy and light curve analysis indicated that the secondary companion was a low mass red dwarf star with mass and radius of 0.13M0 and 0.19R0  The paper is now on the archive of scientific papers: https://arxiv.org/abs/1911.00125 Quite a significant amount of new data from our group. Some interesting departures from early expectations. It will clearly take some ongoing research to identify the mechanisms that are producing some of the effects. Seems to be getting some interest! |
