  1. As Alex.K is in the USA and the image is on a Belgian website, it's unlikely he was the person who appropriated it. The site it's hosted at is: http://telescopemaking.be/ Changing the number in the filename suggests that site has appropriated many of your files. Which links to http://users.telenet.be/telescoopbouw/Welkidex.htm and http://users.telenet.be/telescoopbouw/Welkidex-e.htm This misled me into thinking it was your website (I thought you were something to do with the Urania Project). You might want to do a 'whois' search on telescopemaking.be, but I suspect you may struggle to find who has appropriated your images. According to google it can't find any examples of it, so it must be on unindexed pages. Assuming Alex is nothing to do with that website, he may have found it embedded elsewhere, and it may be a long and complex search to unravel the truth. You can contact the registrant via this website, although their personal details are hidden: https://www.dnsbelgium.be/en/whois/info/telescopemaking.be/details
  2. Traditionally it would probably be a drop of shellac, that is easily dissolved with meths or loosened with heat. UV sensitive adhesive is great for jobs like this, although harder to remove. You can reposition to your heart's content then set it in seconds with a little UV LED torch that comes as part of the glue tube. I've used it for wire cross-hairs.
  3. It's an embedded link, rather than a cut and paste, which, rightly or wrongly, appears to be generally accepted practice. Although an acknowledgement is polite, the URL of the image does show the source and its appearance here should encourage search engines to locate your website. It's legal in the EU and (presumably still legal in the UK) and explicitly does not infringe copyright: https://www.copytrack.com/embedding-images-legal-theft/
  4. I found this on Thingiverse, apologies if I have posted it before. It took some tweaking to get it to run, I can see the clock will be a much bigger challenge! Apologies for the tongue-in-cheek 'clickbait' video title too!
  5. The bit that is often overlooked is that the tooth passing across the lower surface is what gives a kick to the pendulum.
  6. Hi Gina, just to get me following the thread....
  7. No doubt 'Mannakin Skywalker' will have something to say...
  8. Did the retro thrusters fire for the crew capsule? Looked like a hard landing to me...
  9. The platform is more or less horizontal. I have no worries about thread drift! It all seems relevant to me.
  10. Yep, you can get them 300mm diameter. This one has a capacity of half a ton - search 'lazy susan bearing': https://simplybearings.co.uk/shop/product_info.php?products_id=42341&vat_inc=true
  11. I've gone to my laptop and updated/reinstalled everything and now the camera barely works at all on it... still works on the desktop!
  12. OK, my findings; The 'compatible.iic' version: Old desktop: Works in 16 and 8 bit mode in Sharpcap. Works in 8 bit mode in PHD2, but with all split frames. New Laptop: Works only in 8 bit mode, but unstable, doesn't always start unless I change mode) in Sharpcap, doesn't work at all in PHD2. The 'standard' version: Old desktop: Works in 16 and 8bit modes in Sharpcap. Works in 16 and 8 bit mode in PHD2, sometimes with split frames. New laptop: Works in 16 and 8 bit modes in Sharpcap. Now only managed to generate one frame in PHD2 over multiple tries in 8 and 16 bit modes. So... the conclusions are: The 'standard' iic seems to be more reliable than the 'compatible' version. Sharpcap is better able to manage a connection to the ASI120MC with both sets of firmware. The difference appears to be something about how USB 2 is implemented on the two computers (note the 'old' desktop is bang up to date - it did the latest Windows full update yesterday). Looks like I need a new camera for guiding. I've ordered a cheap Svbony one as a stopgap, even if the max exposure is only 500ms my system can cope with that.
  13. If remaking, I would be tempted to use a 'lazy Susan'-type bearing rather than teflon pads on the top - I may even retro fit one. The main issue I found was the draw with pads was enough to cause wobble when manually slewing.
  14. Couple of Osse's 'eads and a Soul from Christmas Eve: HSO SHO: Soul, SHO:
  15. From the night I got my Sii data for the California nebula, 15 December. Note the large, faint halo beyond the blue nebulosity is an artefact. SHO: HSO:
  16. OK... on my desktop, the compatible version stopped it working in RAW16 mode, but the three 8-bit modes were OK. I've gone to the standard firmware and it works in all three modes. I will have to see which version works best with the laptop I use. Thanks!
  17. The current links on the website are to a Windows .EXE and I couldn't find any iic files in the current linux or Mac zip folders. I'll try yours and see what happens!
  18. Can anyone help with a copy of the ASI120MC-compatible.iic file? It doesn't seem to be on the ZWO website and the firmware updater just opens a folder on my computer.
  19. Hmmm... I have the firmware updater. It seems I need ASI120MC-compatible.iic But I can't find it on the ZWO website or anywhere else. Lots of mentions of it, but no download.
  20. It is the USB2 version, quite possibly this is the result of a helpful windows update. The laptop does have a USB3 port, I run my ASI1600MM off it. I didn't realise ZWO had a support forum, I will check there.
  21. Direct to a good spec Windows 10 laptop.
  22. Back from a break A productive evening was the 22 November. I have a strange field of view at home, so along session means I get data on several targets, and at this time of year I often can't revisit for more data. This means these images need to be seen as 'works in progress' that will need more subs adding in the future. Also, I've used Jpegs because my broadband is playing up some of the subtleties are lost (he claimed!) All Baader narrowband filters, except the Plieades, ZWO RGB. 130P-DS, ASI1600MM-pro and HEQ5 The Tadpoles NGC1983 in Hubble Palette: The California Nebula HSO, with the S from an evening a few weeks later. No Oiii under my skies. The FOV is a bit limiting with this setup: Which do you prefer? Pacman in Hubble (SHO) and HSO, in contrast these are crops from a larger frame: Finally, the Pleiades in RGB, knocked off at the end of along evening so just 75-second subs and not very deep: All in all, a worthwhile evening, even if my Witch Head was a complete fail and these do need more data next year
  23. Hi Ken! Looks like a pig that way up...
