Description

I managed to take 76 subs of this, each at 3 minutes long. The integration time was 3 hours 48 minutes. I always find this area of the sky tough to process, but I am pleased with how it turned out, now that the weather has turned once more - we hit 33C [91F] here the other day, but in the UK it never lasts! That said, the summer has been more stable than normal. I also just about imaged the soap bubble in all this - although it is hard to see, hence the additional image. Have a good night everyone...
