Iridium50 Flare 23rd August
Sky Guide predicted this flare at 21:39:09 at my location. So I setup my Canon 1100D using Backyard EOS for a 45 second exposure and ISO400. I collected RAW and JPEG data. I only used RAW as the JPEG seems very much inferior. I kicked off the exposure 20 seconds earlier. EXACTLY on time the flare appeared which I find astounding.
To avoid trailing stars I decided to use my guide camera using PHD2. Was difficult to obtain accurate focus on my main camera but 10-12 test exposures seemed to do the trick. Future focus attainment should be easier as I have now marked the point on my lens which is a 18-55mm. Using 18mm. And in case you wondered, No, you can't use infinity. I have used a LP filter but I was a bit up against it as a distant street light was directly casting light onto the Lens.
You can also see Andromeda Galaxy in the bottom centre part of the image. There is also another object in the picture that I think is some sort of space debris but I am unable to confirm. The mottled effect to the left of the flare is part of the Milky Way, our own Galaxy.
Processing was done in Pixinsight (DBE and NR) and Photoshop.
