    Well, at least peering at the skies...
    Oh, and fish, computing, photography, music and others...

  1. Have you contacted Juan ?? I've always found him very approachable ....
  2. If you have more nuts\washers of the correct size, then you could probably do away with the springs altogether by locking the parts together. Think of the thread as fixed pillar, that you can run the bed up-down on and lock in place... It's how I fix the beds on my printers. It takes longer, with repeated levelling routines, but once adjusted, with everything tightened up, it usually doesn't need further adjustment for a long time.
  3. If you have a Pi, why not install the AllSky software & give it a go, the ASI cameras 'tested' cover a wide range, so I suspect your Altair cameras will work ok....
  4. As Vlaiv, has stated, a decent stepper motor with appropriate drivers, combined with micro-stepping, will easily do what you want.... If you want further info on a 'home-built' system, then have a look at Tom Carpenter's excellent AstroEq system (https://astroeq.co.uk/tutorials.php). I use this system to convert a non-goto EQ5 system to a fully remote controlled system, with all adjustments to rotation etc., being done in software\configuration.
  5. If you already have the connectors\crimper, then buy some of this (https://www.ebay.co.uk/itm/External-Outdoor-Cat5E-FULL-COPPER-Network-Ethernet-Cable-FTP-UTP-Reel-Lot-Cat5/381837841197?epid=14001991729&hash=item58e74f132d:m:mwQOmL3g59EZPfeqt8CT6tQ) At 50m for £16, which to my mind, is a no brainer, you can just tack it to the side of fence panels etc. then forget about connectivity issues.
  6. Just be aware, that there are many bad copies of the DS18B\S20 series of devices. To ensure you get pukka ones you need to buy from a reliable distributor, i.e. RS Components, Farnell etc....
  7. Astroberry is based on Raspian Buster, while the Polemaster software requires Ubuntu Mate, which is what I've got installed\running on a Pi4, so I don't think it will work ok, but I may well be wrong ....
  8. If you've ordered the board from Aisler.Net (Germany based) then they usually only take a few days to come.... As for the temperature probe, I use variants of these DS18B20's e.g.https://www.ebay.co.uk/itm/DS18B20-Waterproof-Digital-Sensor-Thermal-Probe-Temperature-Thermometer-Arduino/111431573979?epid=1386221694&hash=item19f1d6e1db:g:ekwAAOSwxH1T5i~D They are simple 3 wire probes, which I wire up using 'stereo' headphone plugs & chassis sockets...
  9. Sorry Derek, I should have waited to your confirmation, but I just finished packing the trailer, for a trip up either Sat\Sun, and was sorely disappointed....
  10. Hi Peeps, sorry to be the bearer of bad news, but I've just been in contact with Ralph, to check on conditions before I set off, & I'm sorry to say that he tells me that they've had to cancel the party !! as there's just been another torrential downpour, with more forecast....
  11. There's a learning curve with all software, also consider the value of all your equipment compared with the value of quality software to drive it all..... Having said that BackyardEos, APT, SGPro, SharpCap etc. on the windows side, while on the Linux side, you have Indi\Ekos .....
  12. No, you don't need a 9x50 finder, just follow the requirements section of the Sharpcap polar alignment tool....
  13. I must admit, I have 2 600D's, one modded, one not, which for the adhoc, OSC shooting I do, suits me fine....
  14. As reiterated elsewhere, the lower the numbers in a Canon camera series, the better the camera... So the 60D(a) will be better than the 600D(a) camera.
  15. I'd go with the wait, but keep an eye out for a 600d or similar....
