A night in the Garden!

15th November: A very damp and dewy night. I had planned a few hours out in the garden with my scope as the sky was exceptionally clear and I wanted to observe Chi Cygni, to see if it was within range of the scope. As soon as I got home from work, I set the scope up on the patio. At 19:03UT I got the variable within the fov of the 20mm lens. The star did seem fairly bright, a redish colour. Mindful of the fact that I didn't want to star at it too much and bias my magnitude estimate, I grabbed 3 short looks while comparing it to stars of +6.4 and +8.1. Checking with my AAVSO chart, My estimate is +7.9 and this agrees quite well with other reports made to the AAVSO . Afterwards, I dropped down to view Beta Cygni, Albireo, one of the 'showpiece' doubles of the sky. Even at 200x, this is a marvelous colour contrast double with wide components. The primary yellow with the secondary star's blue colour make for a splendid sight! I remembered that the Luminous Blue Variable, P...

Chi Cygni - more images

On the 1st and 9th of November, Brian grabbed a couple more images of Chi Cygni for my magnitude estimates. Though the star is bright on the images, in actuality it is still quite dim and below binocular range, at least for my 10x50's. By going to the Doncaster Astronomical Society Blog you can read and see more details of the images for those dates
