  1. Typing in a hurry doesn't work does it..., too many thumbs, not enough brain power
  2. I used to run the obsy on Netgear ethernet over mains adaptors. When they worked they were good, but would drop out not infrequently. The obsy was powered from the breaker board in my workshop/shed next to it, the run from the house to the shed was cabled in SWA. The adaptor in the shed eventually gave up the ghost three years ago, when I was away for a month in winter, and powered it down. I assume it didn't much like the damp on power up. I now run the obsy in SWA ethernet cable from the house, seemed to solve all problems. Huw
  3. Right, got the Nano clone to work, I had the wrong drivers for the usb to serial chip Uno still miss behaving, but at least I've got something to play with Huw
  4. No, reset button works fine, if I press it the sketch stops then restarts
  5. Thanks Gina, I've actually got two arduinos, the other one is a nano clone, win7 is not recognising that one on USB, claims drivers are not loaded, but also claims drivers are not needed...Blinking computers...
  6. I have an Arduino Uno R2 which ran my autofocuser before I bought a Lightphase focuser. It's been sitting gathering dust in a cupboard, but since I've got some time on my hands I decided to have a play with it. For some reason I can't get it to run a sketch after power cycle, I've seen reports of similar on the Arduino forums, but this board used to run just fine. If for example I upload the 'blink' sketch, it runs fine, then I unplug the USB and reconnect, and the LED just gives rapid bursts of flashing not the steady one second flashes, am I doing something incredibly stupid? ( I admit to not knowing that much about the Arduino, as you can see) Huw
  7. Yes we did, spent two nights at at Denham, and two at Monkey Mia, we're both non swimmers, so topside only for us. Huw
  8. Yes indeed, this was our third trip. In the outback the night sky is well worth seeing, especially in their Autumn, trouble is the Aussies love their LED lighting and generators even in the remotest camping grounds. There was no such light pollution here, but what I was fighting was salt spray filling the air from the Indian Ocean swells breaking on the rocky shore, these are the famous Quobba blowholes. Looking down the line of the shore in daylight the spray was visible everywhere as a mist, and probably reduced the contrast considerably for my Milky Way image. Huw
  9. Yes, they are visible in dark locations, but only really come alive with averted vision. Huw
  10. Had a trip to OZ back in Oct, and finally got round to processing this panorama It was taken at point Quobba on the West coast. You know it's dark when the Zodiacal light counts as light pollution. Huw
  11. That is starting to look like a beast, what size cameras do you intend to hang off it? Keep it coming, it's good to see designs unfolding. Huw
  12. Just to clear things up, in my post above, I called the Gurley encoder an absolute encoder. IT IS NOT, what I'm sure I meant to write was mount encoder as opposed to a motor encoder. I'm not sure where my brain was when I wrote that post, apologies to those I mislead. Huw
  13. The Gurley I'm using (or not at the moment) is the 320K pulse R158 encoder, and it's £882 Huw
  14. If I may add my experience here with trying to add an absolute encoder to my Sitech controlled DIY fork, I bought a Gurley encoder as specd for Sitech (not cheap), and mounted it via a flexible shaft coupling to the RA axis, the body of the encoder was solidly mounted by bracket to the bearing block. I must have some axial offset in the centering of the encoder, it gives differing RA speed, dependant on pointing position, so will have to go back to the drawing board in its implementation. EDIT The encoder is not ABSOLUTE, don't know why I called it that!!! Huw
  15. Best of luck with this project, I've been fighting my equatorial fork mounted 400mm f3.5 Newtonian for more time than I care to remember Not sure, but I think the Sitech system can handle Alt-Az mounts, as well as guiding and de-rotation, see page 22 of this manual http://pgrasc.org/wp-content/uploads/2014/03/SetupManual1-1-a.pdf Huw
