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 […] 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! […] Yes, I did it once while I was building a new observatory. It took me just 3 hours to build!! Roll off shed design. Thick marine ply base with 6 castors to help keep it from flexing, cut out for scope pier. Even put in a dehumidifier. Mine was a bit messy as it […] New light curve for NSVS14256825 binary. Standard plot of mag against time. Check plot to look at a check starGetting a bit low (30deg at end) […] How to Get Started With Astronomy While on a Shoestring Budget Thanks for writing this handy guide.. Now in the LINKS page. Binary star measurement. Using the time variations of the eclipses we are able to calculate the orbit of possible companion objects big enough to have an effect on the orbital period of the binary pair. The picture below is the plot of light magnitude from the binary pair. The timing of this minima is […] |
