  1. I bought myself a very good second-hand inspection lamp. I couldn't resist using it to enhance my processing tomfoolery 🤣
  2. Credit to Octo from B3ta.com (Warning, the whole site should be considered NSFW lol)
  3. Yes, please post the image. Your console output says. "limiting to the 8 brightest stars" When I plate solve in PI, it usually finds thousands of stars. I don't think eight is sufficient to find a valid and unique solution!
  4. Definitely go for new usb cables. But don't go cheap! This is part of the problem. The cables don't need to be expensive, just good. I'd recommend Lindy.
  5. If it's on the internet, it WILL get copied and used whatever licence terms you think you have arranged. What licencing model did bahtinov use for his research and idea? Why are you upset? What are you really losing here?
  6. Maybe, by supporting the core of the area, could it expand as the perimeter residents realise the benefits? ... I'm way too idealistic \o/
  7. Forty+ years ago, I would go to the Portsmouth central library and borrow/read as many books on astronomy as I could get my hands on! Apart from the inspiration to build telescopes, I came across an Apple computer magazine with a rudimentary sky simulator program written in Apple basic. I converted this program into Sinclair Basic, which was not always trivial... ... but the real work was typing in the coordinates, magnitudes, and names, of as many of the stars from the library copy of the Flamsteed catalogue. I do not recall if it was the lack of memory on My ZX Spectrum, the lack of will-power, or my own teenage smelly funk that made me give up at about 1/3 of the way through. But the conversion did work!
  8. This will get you started: Google search results :) I'm pretty sure you will learn a lot. I do understand that when you are new to a hobby, you don't even know what to search for to begin looking! I've been there, and I'll be there again. lol.
  9. What part of the EM spectrum? gamma-rays? x-rays? visible? microwave? VLF etc.?
  10. Just remember that although your filters are parfocal, it is very unlikely that the rest of your imaging train is too. Any curved bit of glass has the potential to slightly change the focus at different wavelengths. Yes, for the best results, you should refocus at every filter change. In practice, due to atmospheric seeing and the sampling resolution of your equipment, you might not notice any difference if you just focus for lum every so often.
  11. I've done that and I've watched you do it too. It is a satisfying process in itself. However, without the luxury of time that a well situated observatory provides, platesolving is a fantastic tool to increase the total integration time over a session. Particularly if switching between multiple targets.
  12. Nice start. This integrates a lot faster with a mono camera and dedicated nb filters. Also you have several pairs of bad pixels that were not properly rejected from the stack.
  13. The capital M denotes "mega". Lower case m denotes "mili". But why let a factor of 10^9 spoil our fun! Lol
  14. From the Ebay blurb: "Power less than 1MW" I should hope so!!! ☠️
  15. I think the idea is to have a universal coordinate system (ICRS) that's independent of the nuances of the earth's motion and to harmonise the disparate (and sometimes less accurate) legacy coordinate systems. The article also seems to stress that the computers will deal with with it all, and we (plebs) don't need to worry our little heads about it. I can accept that bit, but I can see how it could cause you headaches, as you are creating a computer program to deal with this very issue! The paper also asserts that no algorithmic changes will be necessary to existing astronomical software. From this I assume that there is a relatively straightforward linear transform between ICRS and the other systems. I think.
  16. No shouts for Dylan O'Donnell yet? Maybe I just don't like to take stuff too seriously...
  17. You may already have found them, but these people hire out all kinds of stuff. http://www.athos.org/
  18. They're all nice but would benefit from more integration time. But you know that already...lol Sorry Happy new year!
  19. You can still drive all the road past the observatories at night, you just cant get in the gates and there are signs (IIRC) asking you to dim your headlights near the top... I totally recommend, nay, INSIST that you take a drive up there on a moonless night. I did. Words cannot ever describe it!
  20. These new RC tools are impressive indeed! 🤣 @ngc1535
  21. I concur with @sharkmelly If it was the chimmey stack, the artefact would move in relation to the sensor as the scope tracked and would largely be rejected in the integration process. As the pattern is well defined and looks like a bright star artefact, I also conclude that is what it is.
