  1. Hi all is anyone planning on attending the show ? cheers gaj
  2. Hi there you keep referring to 'zoom'. The control knob at the eyepiece end of the scope is a focus control not a zoom. If that is what you are using to zoom then you are simply going out of focus and the star will get bigger and be a blur. Hope that helps gaj
  3. Hi Ian Don't remember using an abacus but we did have them at school. I used Algol when I was at university. Similar to you, typing the program into a teletype tp produce the paper tape, the queuing to feed it into the Elliot 901 ( I think ) before getting an error message. Then back to the teletype and stepping through the tape till you got to the error, inserting a correction and then stepping on with the copying of the tape. It's no wonder I had no interest in computers back then. It was at a British Gas Research station I really started with a 6800 processor. Then on to an aerospace company where I used 9900 processors. I think the mil version was £400 and that was late 70s, so a lot of money. And that my friends is how I became the great success I am today - oh hang on! What a great time though. I never wanted to earn a lot, just be involved with interesting projects and I did that alright. Gas turbine engine controls, flight management computer, helicopter auto-stabiliser, motor cycle engine controls and finally diesel engine controls. And I would say, I think Tomorrows World played a part in grabbing my interest. And now retirement and I get to do my own thing. Who knows where that will lead. cheers gaj
  4. Sounds interesting. I loved those analogue days. Up until retirement I had saved loads of 'useful' bits that I planned to put to good use on the cold winter nights of retirement. Oscilloscope tubes, loads of power transistors, motor rotors ( for brushless motors ); all sorts of things. Back in the 70s there were loads of designs for audio amps and synthesizers were really taking off. I had thoughts of reliving that era. And then reality set in and I realised that I probably wouldn't spend a lot of time making something that I can buy from China for silly money. So now, I'm playing with quadcopters instead. Hey, adapt or get stuck in a rut. Oh yes - and I'd quite like to do some astrophotography if we ever get appropriate weather. cheers gaj
  5. What device was that Gina? I did a couple of years designing analogue ICs myself. A fascinating time but it was a nervous time waiting for that first silicon to come back. cheers gaj
  6. Gina. I too started with a slate. I like to think it was an early Tablet! I also used my first microprocessor back in 1974 ish. It had 128 bytes of RAM - not kilobytes - bytes. I loaded programs ( albeit small ones ) with paper tape loaded from a teletype. Later I added a fast tape reader and stored subroutines in an EPROM. I wrote in machine code and learned most of the common 6800 instructions. We didn't have a development system - well it was British Gas! Starting to sound like Monty Python's eating gravel sketch here. Best stop. cheers gaj
  7. Hi all. I am not alone then. The thing I always remember was the voice recognition software. No matter how many times they demonstrated a new one, it would fail to work on live TV. There is a lesson for us there. It may take time but technology will overcome the problems. The driver-less car is a case in point. To me the interesting thing is the social effects of the new devices. I grew up in a time where not every home had a phone and it was quite common for your watch to stop because you forgotten to wind it. Now the smart phone has just blown all that away. Social networking and all the data you could ever want. Who would have thought it. Connections was a good program too. James Burke was a master presenter and Connections was an interesting insight into how we got to be where we are. New ideas built on old with the assistance of technological advance. I like Click too. To me, more about software developments but then I suppose most things are now. Now that I have retired I hope I can keep up with the changes. Just before I retired I asked a chap at work how it was best to transfer my CDs to my phone. He looked at me as if I was talking about wax cylinders. "Why would you do that when there is Spotify?" Well I could think of several reasons but then I'm a bloke that still has a fountain pen. cheers gaj
  8. just listening to James Burke on Radio 4 extra talking about Tomorrows World. Great program. Is there anything like it today? If so I haven't found it. gaj
  9. Only watched a bit, but the argument at that section was that a guy had managed to view things a long way away that should not have been visible if the earth was curved. Hmm. Some people can be hard work. I have better things to do. Thanks for the link gaj
  10. Hi. My first question would be: does it track correctly? I wonder if the 'banging noise' is the stepper missing a step which might indicate binding. Perhaps meshing is too tight. Just a thought gaj
  11. I started with a Nextstar 4SE. I had a camera with adapter connected to the straight through and a lens on the upper position. I made an extension to ensure that the lens was in focus when the camera was in focus. It got me started. I got some results for Saturn and Jupiter but it wasn't any good for deep sky objects. I haven't tried any guiding with it. The tracking is fine for viewing but wont be much good for long exposures. Here is my advise. First read the excellent book Making Every Photon Count. Then read it again. You need to decide what you want to photograph. Planets require different techniques to deep sky objects. Be prepared to spend time and money. Good luck
  12. Hi again thanks for your help, but it's that last statement that is my problem. I don't know how to find out what it is called. On my PC the BT home hub page on my PC browser shows the pi as "gajjer-desktop" with as the ip address Also interesting that you refer to port 8264 whilst the INDI documentation refers to 7264. It's all very confusing The PC and pi are on the same server. Think I have a lot more trials and reading to do. thanks gaj
  13. OK. I'm not sure why I would need to load kstars/ekos onto my remote PC unless I was doing more than guiding. Also, if I did, how exactly do you go about connecting to the Pi - ie commands I think that initially I will just try the second option of remote access from the PC. What I need is a precise sequence to carry out. Do I just use remote desktop connection? Of so what is the name of the pi? How can I find out? I know what my login name is but I suspect that is not it. thanks gaj
  14. Here again I've got another Pi 3 now and I've loaded up the INDI software, kstars and ekos. I'm reading through the documentation now. I think I understand what it does now, however I do have some very basic questions 1. I can fire up Kstars and ekos on the Pi. What do I need to do on my PC. Does it need some INDI software there too? I'm running Windows 7 on the PC. Or do I use remote desktop? If so what is the INDI server called and how do I access it? Hoping someone can help. cheers gaj
  15. Hi again Thank you all so much for your input. Ido appreciate it. It does seem sometimes like "well I was going to get there, I wouldn't be starting from here". I had a go at this once before using the pi motion software trying to just do remote capture with a headless pi. I got so far with VNC : I could control but not see the captured image. I was told at the time that VNC couldn't do that and gave up., ( My head will only take so much banging against walls ) The advantage of astroberry seemed to be that it was all contained in a single image and did more than I wanted. I will find some time to play over the weekend and let you know how I get on. Thanks again Gaj
