  1. Came across this page on Sourceforge which lists all the astronomy projects. I've found individual ones before but never this section with all of them; perhaps I haven't been going about it the right way. I arrived at the page from Millionshort.com which is a search engine I've only just found. Interesting to be able to filter out all the big names - ebay, amazon, wikipedia etc. They claim to be hot on privacy. Hmmmm. Eric.
  2. Does the motor not move at all? Or does it rotate but doesn't turn the focuser? If the latter, then the rod needs to be more firm against the focuser. I did this mod to mine, and the motor now moves the focuser with an 800gm spectroscope. Eric. https://youtu.be/ofOSAMlqZWw
  3. Why no Sky at Night TV program this month?

    I've felt of late that the Sky At Night was losing it's amateur appeal. It's very interesting finding out about latest advances in astronomy, but those are covered in other one off astronomy programmes. Perhaps more of a down to earth approach for amateurs, especially new ones. Projects to complete, things to look for in the night sky, up and coming events, practical things which ordinary people can do to help them in their observations. Eric.
  4. I use one. It's a leftover from an eye exercise program I bought a few years ago. I find it easier than squinting. Eric.
  5. Sorry to hear it doesn't work for you. I only mentioned it because mine has worked ok. Hopefully you'll get some response from their support, or you can always return it to Amazon. Eric.
  6. My devices don't power up either if they're only plugged into the transmitter. You need to complete the connection to your laptop using the Cat6 cable and the receiver as well. Connect the receiver to the laptop with a USB cable, start the laptop and once its booted up the devices should power up. Eric.
  7. No. Just a couple of Altair Astro cameras. Eric.
  8. I use these from Amazon https://www.amazon.co.uk/dp/B01EV33R8S/ref=pe_1909131_77697001_tnp_email_TE_AMZLdp_1 I use all four ports with one Ethernet (RJ45) cable back into the house. Cable can be up to 50m. I've noticed some devices (or software) are a bit picky about which port they like. For example, with a camera connected to SharpCap it seems to prefer to be connected to no.1 port. Once I figured that out the whole system works very well. Eric.
  9. 12v Power Connectors

    I use 3pin XLR connectors. They are quite substantial and lock into place. The cables are also gripped firmly. I bought them on ebay https://www.ebay.co.uk/itm/121793510831 Eric.
  10. Greeting from Genoa,Italy

    Welcome to the forums, Andrea. I visited Genoa about seven years ago when I was staying in Santa Margherita. Also did the Cinque Terre walk, wonderful scenery. I hope you have clearer skies in Genoa than we have here in the UK! Eric.
  11. Try this link: https://github.com/Stellarium/stellarium/releases It seems to have all the available releases of the software. Eric.
  12. Congratulation! My StarAnalyser still gets a lot of use even though I'm moving on to higher resolutions. It's a fascinating aspect of astronomy. Even on bright moonlit nights you can still capture spectra. Zero image on left, spectra on right, and as level as you can get it. Eric.
  13. This one has been under discussion on the astronomical-spectroscopy Yahoo group. https://en.jeulin.fr/simple-radial-slits-212076.html Eric. ps. Welcome to the forums! (Just noticed this is your first post)
  14. Yet another power box thread

    I made a wood box to hold the leisure battery, with a lid which I leave open when recharging. I used 3 pin XLR Audio sockets and connectors because they lock in place and can't come out accidentally. Much better than the ancient cigar lighter plugs. Eric.
  15. Is this power supply ok for the HEQ5

    Does this produce what is known as a linear output, as opposed to switching? I'm no expert, just asking. Eric.
