Hi, I am new to this forum, and certainly not an experienced astronomer at all. However while I was out in Herstmonceux, East Sussex during the 2016 Perseid meteor shower on the 12th of August 2016 at around 1am, I saw something pretty strange in the sky. As I was lying on my back looking up at the sky I noticed a small green point of light in the sky, about the size of an average star. It was moving around the sky, it looked slow but given its (supposed) distance I would say it was actually moving incredibly quickly. It couldn't have been a plane as it was a single, tiny point of light changing direction quickly. I live very close to the Greenwich observatory in Herstmonceux, East Sussex and I see their green lasers pointing out at the sky regularly between 8pm and 12pm usually and this also wasn't it as there was no beam, literally just a single point of bright green light moving amongst the stars. I have absolutely no idea what this could be, but I would love to hear peoples opinions or thoughts on what it could potentially be, or if anyone has seen anything like it before.
I was asleep in my bed about three hours ago when something extremely loud woke me up. It was my fish tank light and filter turning on and off two or three times. Immediately after this happened, there was a seriously bright sheet flash of green light that didn't cover the whole sky, but a great deal of it. Following the green flash, four car alarms went off in my street and there was a loud electric pulsing noise twice. One of the weirdest parts about this though, is that my fish tank is plugged into the same adapter that all of my other electronics are plugged into, yet it was the only thing to change during this occurrence. Needless to say, I cowered like a little girl and slept on the floor in my brothers room. Any suggestions? I've looked it up but can't quite seem to find any articles like this anywhere.
Hi guys, so I finally got my HEQ5 PRO mount to track correctly and I decided to take a bunch of photos of the Orion Nebula(or at least part of it). I took as many photo's as I could with my Canon 1000D DSLR connected up at prime focus. I used 1600 ISO (max), 400 ISO and 100 ISO all with a shutter speed of 30" I have found these red, green and blue squiggles I think are called 'hot pixels' in all of my photo's after I've used DeepSkyStacker to merge them. They may be hard to see on here but in Photoshop they are everywhere Could someone please explain to me what is causing this and what can I do to avoid it in the future please. I feel like I've ruined a perfect night out! Or maybe there is a way to fix this? I was using a Skywatcher 200p for these. ISO 1600 30" ISO 400 30" ISO 100 30" Thanks, guys!
