11th AugustPerseid meteorsSo far I have always been unsuccesful in photographing meteors. I now have a Nikon D810A camera with a wide aangle lens, so the task is much easier. In 3 and a half hours I saw 22 meteors and captured 3. ![]() Star Trails The D810A camera has a built in intervalometer, so it is easy to take a sequence of images. The free software StarTrax overlays images to produce star trails. 26th August I was at a location with a much darker sky than mine so I made a star trail image with Polaris near the centre. This eliminates distortion produced by the wide angle lens. ![]() 29th August M31 is now accessible so the nova search continues. No new discoveries, but two recent discoveries were seen. M31 2016-08b ![]() M31 2016-08d ![]() 30th August This one escaped me - I missed it on my image blinking. It was discovered several hours before I started, by observers in Japan. ![]() Barnard's star This star has the greatest proper motion of any star in the sky. This animation compares positions in 2014, 2015 and 2016. (The star is moving upwards). ![]() |
