Gamma Leo (Algieba) 2.2, 3.5 4.4" 120deg (60mm 175x, 102mm 206x, Webcam uR)
Algieba is a true binary system 100 lightyears away. The stars orbit each other with a period of 620 years.
This is first attempt at imaging a double star. Unfortunately, I was looking at the wrong pair. I should
have been trying to resolve the two components of the bright star on this image. Instead I have a picture
of this binocular pair
The image was taken at 320x240 so it is only 1.8" per pixel so 4.4" separation is only 2.5 pixels. The
enlargement below shows the pixels magnified by a factor of eight. You can just about imagine that there
are two stars waiting to be discovered.
Things to try next time:
- Still at 320x240 resolution, try a shorter exposure. In this initial image, I set the exposure
for the unrelated 5th magnitude star. If I concentrate on Algieba, I might be able to see both
component stars on the screen. Both components are bright (2.2 and 3.5) so it might be possible.
- Try 640x480 resolution. This resolution gives 0.9" per pixel so the 4.4" separation would be 5
pixels. (Probably the easiest way).
- Try this at the start of an observing session. My laptop only has 1 hour battery life while
running VRecord. I might have to get some sort of extra power supply.
