  1. I'm fairly new and on one of my daily stargazing sessions I viewed, with the naked eye, a huge passing light going SE, from my perspective it was brighter and bigger than any stars, planets or meteors that I've seen before. It was roughly the size of a baseball. If this was a star -> . this is roughly how big it looked -> O It had a trail of similar size, seemingly dusty. It also passed and disappeared between Corona Borealis and one of Hercules' legs. Viewed on May 16th, 22:00- 23:40 I assumed, based on recent headlines, that it was Comet Swan, but upon further investigation, that was far from true. Comet Swan should not be visible with the naked eye, and definitely not to the degree I saw. Additionally, based on my coordinates* it wouldn't even cross the sky I saw, it would be below the horizon. (*roughly 15 °N, 120 °E, PH) Considering again the magnitude of the object amd the fact that I viewed it with the naked eye discounts it from being an asteroid or meteor*. (*More possible but still hard to believe with its size, you wouldn't even see something like that during meteor showers) So I then researched if it could be space debris. I thought that something as big as that should be covered by a news article somewhere. *The only results were of the 18 ton Chinese Rocket but it couldn't be that because: A. It passed over Los Angeles and New York then fell into the Atlantic Ocean, with some pieces landing in Africa. Meaning it wouldn't pass over my country. B. That happened 5 days before my viewing, on May 11 at 11:33 AM ET (08:33 PDT) It's still possible but it just seems unlikely, and with how big it was I'd assume that it would attract some media attention but I cant find anything else. Does anyone have any idea what it could have been? I have to know. If it was debris then all I need is confirmation. * https://www.google.com/amp/s/www.cnbc.com/amp/2020/05/16/chinese-rocket-falls-to-earth-space-debris-problem-worsens.html https://www.google.com/amp/s/www.theverge.com/platform/amp/2020/5/13/21256484/china-rocket-debris-africa-uncontrolled-reentry-long-march-5b
  2. 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.
  3. I've finally got around to making my flats box. I decided to go for a cylinder rather than the normal square as I thought it would maximize the amount of reflected light and limit any 'dead' areas. I could also use the Celestrons dust cap retaining pins to lock the flats box onto the 'scope. I purchased some of the craft board that has a thin foam sheet sandwiched between two sheets of thick paper/thin card. In order to bend the card into a cylinder, I creased the board every 20 mm by pressing the edge of a steel ruler into the board. It took two of the sheets to make a cylinder big enough to fit my C9.25, with only a couple of cm trimmed off. I then made a reinforcing ring/defuser holder from two strips of the foam board; this time creasing them at 15mm intervals. I stuck these level to the bottom edge so the joins were 90° to the main cylinder joins. These strips were cut wide enough to ensure that the diffuser cleared the secondary housing. The cylinder was designed to lock into the C9.25s dust cap retaining pins so next I cut two keyways into the bottom outer side. They looked a little weak so I reinforced them with some Christmas chocolate reindeer plastic packaging! Although the foamboard is quite shiny, I wasn't happy with all the grooves, so I lined the inside with white A4 paper. The Perspex sheet was cut to shape and hot glued into place onto the ledge. Next, starting at the top, I notched the edge of the cylinder to run the LED string lights cable through and then started to spiral the LEDs around and down the cylinder. The top cap/reflector was made from two discs of foamboard. One to go inside the cylinder and one to sit proud of the edge. They were glued together before being hot glued onto the top of the cylinder. The LED light string that I bought has an integrated on/off button as well as both up and down brightness buttons with a 3M sticky pad on the back, so I stuck this to the top cap. As I had previously made myself a 'scope mounted power distribution box with aircraft sockets for power, I removed the 3 pin UK plug/ac-dc converter and soldered on an aircraft plug to match my 12 volt DC supply socket. The lightbox illuminated.
