  1. Yeah, I will have to sort out some flat & bias files. I think part of my problem with processing is the difference between linear and gamma TIFF files (possibly part of why the vignetting wasn't removed by my gradient removal). I will have to experiment with such.
  2. Camera was on an unmotorized tripod, I took 183 4 second exposures, adjusting the camera's orientation every 60 shots. I used all the space on my SD card.
  3. Last night I went out to the front garden with the camera & my 10x50s. It wasn't perfect seeing but there weren't any clouds this time. I had a look around and the best target for the camera seemed to be the heart & soul nebula, so I se the camera going on that. Taking my glasses off to use the binoculars, I saw the milky way actually pop out at me. It was just about visible with the glasses on but became an easy sight with my glasses removed, with the binoculars I had a glance at M31, the double cluster, tried for M101 and felt like I might have gotten it (not sure), saw the omega & eagle. At this point I realized just how good I had it compared to a lot of people. Being able to just step outside with my 10x50s and see some of the best objects in the sky with ease, in spite of the white street lamps either side of me. The only thing I feel I can lament about is my eyes' astigmatism. The image itself came out fairly well, the 105 2.8 is an improvement over my 18-55 in several ways although it suffers in sharpness across the field wide open. Heart & soul faintly visible, shame the stars all seem to be a bit bloated. P.S. Posted in lounge as talking about observing & imaging, and wasn't sure which of those two sections to post in... Hope you guys have some clear skies!
  4. I'm unmotorized, but my 105mm f2.8 seems to be producing some nice results as long as I use ~4 second exposures. Last night I pointed it somewhere in the milky way and found that I would struggle to process an image which had the milky way cover the whole field. My current ideas are: Andromeda galaxy (Should be fairly easy, right?) M101 & surrounding area. Could be good, but maybe the target is a little small? Heart & soul nebulae. Veil nebula. Perhaps a bit dim, also rather high up & possibly difficult to point at with a regular tripod? Suggestions from that list and other possibilities well welcome Thanks!
  5. Yeah, the other night the seeing was so good I could see the join between the sea and the horizon... Normally by the sea there's at least a little bit of haze, even near the ground. But not that night.
  6. Everything seemed to be fine right until we stepped out the car, to see about 40% of the sky covered in cloud. The forecast had been positive and it seemed OK when we left the house. Thankfully, in a small blessing, the cloud was in large clumps so we could see parts of the sky at any given time. We managed to see the veil (by 52cyg) and the ring nebula, also some star cluster in the middle of the milky way underneath the Sagittarius star cloud which I could have sworn had a dark nebula inside of it, but who knows. Worth getting out to remind me that there is at least something up there, the weather has been so bad recently I was starting to forget there was something above the clouds.
  7. The forecast suggests that either tonight or tomorrow I will get some observing time. Please let the forecast be right, the dob is gathering dust :( And I have the focuser fixed now!

  8. Well yes, standard currency as a concept exists because trading chickens and cows isn't exactly ideal. But the concept is sound in what I said. Because humans cannot do everything, we decide to specialize. Humans also cannot live off their sole section of work. Someone who knits all day relies on farmers for food & wool, a farmer relies on someone who can build & maintain buildings. As such, all core aspects of human effort are interconnected and interdependent. A farmer is rewarded for their effort because by giving away milk from their cows, they can stay warm or have a house to live in. In effect, standard currency is a measure of how much someone's effort is worth. Currency maintains value because it is a promise, but it is merely a convenience to avoid trading an endless stream of goods for goods. If I am being paid 25'000£ per year, that means the company employing me thinks my effort is worth that much to them. Without effort there is no value, without value no-one would use effort.
  9. And yet it becomes harder and harder for university graduates to get jobs, and graduate job pay has decreased significantly since the 90s. All at a time when robots were able to automate many aspects of production (e.g. the robotic arms in car factories which do all the welding 5x as fast as humans, and seldom make a mistake). Also, you can now run a business on a fraction of the staff you could previously. Google hires 60'000 people, and makes about 50BN$ a year. They earn 840'000$ per year per employee. That's insane. The thing is: an economy uses money as a method of distributing effort. If you have money, you have what is basically an "effort token" which you can give to someone else in exchange for them putting effort into something. They then use the same effort token in an exchange for someone else's effort (i.e. food, a house). If humans don't have to put in effort, money becomes useless. Money is a measure of effort and will, and if the machines do all the willing, no human needs money. If the machines reach the point where they're making our films, they have reached the point where they can maintain themselves without human effort, where the machines design & build their successors. No human needs money because no human need put effort into anything. In fact, even if a human were to spend its whole life trying to beat a robot at something, it couldn't. So why bother? Just ask the robots what you want done and they'll do it all for you. No human could buy a company's product, but no company would need to pay for anything after a while because the machines maintain themselves, with their own collective effort.
  10. Just think, when true artificial intelligence is created, what will happen to our expectations of other humans. An artificial intelligence that needs no food, no entertainment, no space. Just routine servicing (which would be less expensive than medical costs for a human) and electricity. It could take every single factory job, every single warehouse job, every single job involving manual labor would be cheaper & more effective to use a robot. The only jobs that will be safe in the early days are creative jobs (art, film, games etc) and perhaps scientific jobs (I also debut we would elect "mindless robots" as leaders of our countries). But 80%+ of jobs in the modern world would be gone as far as humans are concerned, and with a growing population how will we provide work for everyone? Not everyone is fit to be an intellectual, and unless we adapt QUICKLY universities are not equipped to provide the entire population with doctorates and professorships. Unemployment would skyrocket. The only option would be to have CRISPR babies born with extraordinary intelligence: Something only a small portion of the would would be able to access & can be abused. But that won't save us when the artificial intelligence manages to become better at even scientific & creative work than us. Even if it has no emotions it would still be able to understand ours better than we do, and make better creative work as a result. No jobs would be left that humans can compete in. The scary thing is, this is already happening. Computers can analyze images and pick out things humans couldn't. Computers are better at CAPTCHA than we are already. Computers can tell if a human is lying better than a human can. Computers can figure out which images of hotel rooms look more attractive to humans than humans. Artificial intelligence has no attention span, doesn't suffer for boredom, doesn't need to socialize or learn. It can just copy knowledge and experience from it's brothers and perform a job instantly. Call be a pessimist, but anyone born today may not be able to find a job at all by the time they are 25.
  11. I'm now reminded of a game I play a lot of at the moment called Stellaris. You play as a species that has just developed faster than light travel and explore and colonize the galaxy, eventually meeting other species who have just done the same. Depending on their "ethos" they may like you, or be "fanatic purifiers" who you would rather avoid. Sometimes you encounter a "pre-FTL species" which lives on a single planet, like yours did before the game started. You get to build "observation posts" above their worlds to monitor their progress and you receive updates on changes in their society. Quite often they reach "early space age" or "atomic age" and nuke themselves, which turns their planet into a "barren world" with 0% habitability. There is even an event where one of your science ships can study a barren world, and discover that it was once home to a pre-FTL species which suffered such a fate in the "early space age". It mentions the logs from one of their rudimentary space stations, saying "The communications from the astronauts became more and more frantic as the days passed, slowly realizing that nobody was left to save them." The best we can do is hope our own astronauts don't have to face a similar demise because of stupidity down here on earth. A cone, about my height and width, is capable of leveling a small city and making the area around it uninhabitable for decades. But don't worry, international treaties only allow countries to put up to ten on a single rocket.

  13. Wouldn't the planet's core need to be melted again in order for it to keep an atmosphere for any extended period? AFAIK (I'm not a cosmologist/astrophysicist/etc) the molten core provides a magnetic field which protects the atmosphere being blown away by solar winds. So mars would be stuck with minimal air pressure (0.6% of earths?)
  14. I suppose the NGC 1964 post does answer the question. Thanks
  15. Say, for example, you had a 50mm lens at f6 and a 100mm lens at f6. If you pointed them at the same DSO (say orion neb down to witches head FOV) obviously you would expect sharper results from the 100mm, but is there an affect on other aspects of the image? After all, the 100mm is gathering 4x the amount of light, but also trying to focus light from a smaller field of view, so my assumption would be that: Stars would be brighter in the 100mm (might lead to stars becoming more overcrowded due to wide fov?) Nebulae would be the same brightness in the 50mm & 100mm, but fainter detail in the nebulae will come out faster in the 100mm? I can imagine there are many astrophotographers here who have used a wide array of apertures & focal lengths, and can shed light on this matter. Thanks P.S. I haven't been around here for a while, clouds & daylight savings have done my observing in (hopefully getting some observing done on the 12th next month if all is well!)
