  1. It's not so much about the actual star shape rather than the diffraction spikes. Each filter produces an intermittent spike (dotted?) which has a different pattern for each narrowband filter. When all three channels get combined this results to "longitudinal rainbow" diffraction spikes.
  2. I see your point. There are two reasons that make me want to try RGB stars. One is that I don't like magenta SHO stars even with inverted green SCNR, but that is sort of fixed with adding HOO stars instead. The other reason is that ultra narrowband filters produce really weird diffraction spikes with my newt that don't coincide between filters. Other than that I completely agree with you, no need for true colour stars in a false colour image.
  3. I would definitely use a beefier tripod to make the mount justice. In my setup (harmonic mount & eq6 tripod) even finger pressure on one of the legs, sends the guiding RMS from 0.6" to more than 1"
  4. The lobster claw in SHO palette with HOO stars. Although HOO stars are better than SHO, I think that I should really try to take half a hour worth of data in RGB for the stars from now on... Equipment used: Bresser 150NT-s & lacerta GPU cc, pegasus astro NYX-101, QHY9mono, Baader UNB filters, OAG with sv305pro Ha: 47x1200sec binx1, OIII: 49x1200 binx1, SII: 27x1200 binx2
  5. This is another nebula I captured this summer. As I mostly image during July through September, summertime is for harvesting data and winter for processing. Equipment used: Bresser 150NT-s & lacerta GPU cc, pegasus astro NYX-101, QHY9mono, Baader UNB filters, OAG with sv305pro Ha: 45x1200sec binx1, OIII: 40x1200 binx1, SII: 21x1200 binx2 Hope you enjoy it!
  6. Well, in science you need an assumption (theorem) and the actual verification (through multiple observation & experimentation). We observe and verify, so are actually doing science, especially in times where even our planet's shape is questioned.
  7. This is my version of NGC 6820. Faint nebulocity with interesting details, might have to go back and gather more data next summer. SHO palette with HOO stars. Equipment used: Bresser 150NT-s & lacerta GPU cc, pegasus astro NYX-101, QHY9mono, Baader UNB filters, OAG with sv305pro Ha: 29x1200sec binx1, OIII: 23x1200 binx2, SII: 31x1200 binx2 Thanks for looking!
  8. I like playing with equipment too, but to be honest, it's like an endless tweak. Perhaps the best route is to concentrate on a decent one scope/camera setup, iron out all of its quirks, and image, image, image, process, process, process.
  9. @sajmons It would very nice to see a CC plugin for NINA. Would it be very difficult?
  10. Thank you for your kind words. It certainly deserves more attention. I've shot the central part of the nebula as well as Sh2-170 (a.k.a. the small rosette) in the past, with a mono camera at 750mm, so I may try to integrate the data in this widefield image.
  11. This was my last imaging session for 2023. Shot over two clear nights during Christmas (full moon of course 😆). 90x300sec, total of 7.5 hours. Equipment used: Nyx-101, Canon RPa, Canon FD 300L @ 2.8, IDAS NBZ. Thanks for watching! 👍
  12. That's a great attempt on this target, congrats!
  13. No need to start a new thread, this is the full 56 hour SHO version.
  14. This summer I managed to gather approximately 55 hours of data in Ha, OIII & SII of the wizzard nebula (NGC 7380). Things didn't go smoothly, as my collimation had to be redone after three nights and my data aren't as good as I expected. Anyway I am starting to process them, starting with hydrogen and oxygen and this is my take on a HOO image using 36 hours of 1200sec subs. Equipment used: Bresser 150NT-s with Lacerta GPU cc, Pegasus Astro Nyx-101, Qhy9 mono & Baader ultra NB filters. Bortle 6 Thanks for watching!
