  1. Thanks all for your input. This has given me much food for thought. Matt
  2. Budget is going to be around £400 tops and, as for the remaining questions- I have absolutley no idea what you are talking about! I really am new to the prospect of astro imaging beyond attaching my DSLR to my scope and getting single frame images of my target. Part of my tentative stepsinto astro imaging will be learning the dark arts of processing. Matt
  3. I am looking to start building an imaging rig. To start with I want a camera that I can mate to my Skywatcher Explorer 150P. I will initially be doing unguided Solar, planetary and solar but will eventually acquire a guided mount or motorise my EQ3/2 for some deep sky stuff. I have been using my sony DSLR and intend to upgrade that camera but want to get an astro specific unit. The budget won't be huge so a starter camera on which I can learn is the aim. Thanks. Matt
  4. Yes, the massive stars did the Elden Tyrell Blade Runner speach to Roy Batty bit- The light that burns twice as bright burns half as long" and subsequently blew up in hypernovas. These explosions created and spread the universal building block heavy elements such as iron, carbon, oxygen and also cleared the hydrogen atom fog that was causing the cosmic dark age. The hydrogen molecules coalesced into smaller stars and galaxies and the universe as we know it started to grow. An interesting fact for those considering spectroscopy is that the first or second generation stars as we know them were very low in iron. The younger a star, the more iron is present. A star has been found so low in iron that it is estimated to be from only a few billion years after the Big Bang.
  5. On last night and available on iPlayer. Very interesting. For the first 100 million years or so after the Big Bang, the universe was a dark place- no light just hydrogen atoms scattered randomly accross space. Things then started to happen and massive stars formed, so big and so hot that their life was measured in millions of years. Susbequent Hypernovas started to scatter the heavy elements that made the universe as we know it possible and also started to clear the fog of atoms. Etc.
  6. I am putting this in Astro Lounge as opposed to DIY Observatories because, well, I probably won't be doing it (all) myself....... I stuck my neck out at my societies AGM and raised the prospect of having our own observatory. Arguments against were expense, lots of folk have their own dome, location and security. Arguments for included outreach, lots of folk want but can't have their own observatory, skills progression. I was tasked with a feasabilty/ cost study before we decide whether to approach organisations for either funding assistance or permission to site an obsy on their ground. To kick start the costing side of the study, I need to asses what is required (outside of a plot of land for the obsy). My first thoughts are:- Shell. I am thinking sustainable so a substantial wooden structure including a dome and warm room. 'Flatpack' with DIY assembly would reduce financial impact. Perhaps increase the warm room size into something large enough to become our meeting hall? Power. Mains would be best but, would a solar panel/ battery combo suffice? Pier. This would be one of the DIY part of the project and I am thinking a reinforced concrete pier with mount fixings to suit the desired mount though a steel pier is a possibility. Water/ Drainage. As a society obsy, with outreach use a goal, somewhere to produce refreshing beverages (and to download the later result) may be desired. Mains and sewer or mains water and septic tank? What have I missed? Thanks Matt

    Alan Bean, 4th man on the Moon dies

    Master of understatement as well- "Someday maybe a great place for a vacation"..... RIP Alan. Another of my heroes passes.
  8. Last year, at my Societies AGM I raised the possibiltiy of building our own obsevatory. According to the minutes, I offered to do a feasabiltiy study of getting a site to put one! News to me but there you go...... Our 2018 AGM is looming and I have offered to actually do the study- approach colleges, schools, airodromes etc. to see if someone would allow the society to set up an obsy and warm room. What should I be considering in my search for the right place? I am looking for giudance beyond the likes of good horizons, dark skies etc. What I would be grateful for are the out of the box considerations- the things that make you go "Doh! I should have thought of that before!" Thanks all, Swoop 1, Mad Observatory Seeker In Chief.

    DaveS's Obsy Build. First thoughts.

    Could you go for a shed roof pattern with a fold down 'flap' to the high side to open up the horizon? This would reduce the bracing needed for the pitched roof?

    Random Luna stuff from 28-3-2018

    Nice images Ibbo. The first image is where I was looking when I opened my topic in Lunar Observing Bright smudge NW of Sinus Iridium (I think)- The largest crater just off the rim of Sinus Iridium- the one closest to the top of the image- 5 o,clock of that is a smaller crater, quite close. 5 o'clock of that crater and about 2.5- 3 times as far away is another, slightly larger crater. Close to and about 4 O'clock of that crater is a bright, elongated smudge. It looked last night like a dust cloud as I couldn't resolve it. Studyong your image, it now looks like severl bright points, probably where the sun i hitting ridge tops etc.
  11. At 22:15 BST this evening I was taking a tour of the terminator and, as I was studying the vicinity of what I think was Sinus Iridium I saw a very bright smudge to its North West. I managed quite sharp focus on the crater edges but the bright smudge woukd not resolve. Studying my lunar map I beleieve the smudge was either on the edge of Foucault or Hacpalus (Foucault if Hacpalus was disected by the terminator). I have no idea what I was looking at but, it looked almost like ejecta catching the sun as it settled back to the lunar surface. Madness I know but.........

    DIY rotating Nissen Hut or Pulsar 2.7m?

    Fantastic work Rusted. I can't wait to see the finished article. I bet it will be visible from space
  13. There are a couple of equations relating to how many 'scopes/ EP's/ filters/ cameras an astronomer needs- N+1 where N is the number of items currently owned OR S-1 where S is the number of items that will push ones significant other over the edge........
  14. A very satisfying feeling isn't it? Well done!
  15. I normally get away with it but every so often, she reminds me who is boss!
