  1. Nice, you've captured some detail. Focus does look a little off but not bad. The mask will probably help. Stars look fairly round to my inexperienced eye but some more experienced users may have more to say. Good job - looking forward to the next one.
  2. Wow, looks great and especially impressive that that is just one frame.
  3. Looks nice. There is some surface detail in there in addition to the pole. All I see through my scope is a coppery, sun-like ball.
  4. I agree about photoshop. Gimp is really powerful, but probably not quite as full-featured as ps and less user friendly. The main drawbacks of non-WIndows, to me, are no photoshop, fewer games, and no office for the case when you need to collaborate with office users (there are good alternatives if office compatibility is not important). Well, OSX has ps and office, so I guess that is a linux drawback. I do use high-end NVIDIA graphics cards for both visual and CUDA applications and don't have trouble with them at all. NVIDIA provides and frequently updates their drivers in linux as well as windows. The HPC (high-performance computing) world is dominated now by computers with CUDA GPUs and almost all of them run linux - GPU support is solid, at least for NVIDIA GPUs. I've found network printers are supported very well and linux finds them without any hints and gets the proper drivers for any printers I select. Haven't tried connecting a printer directly to the computer. My Nikon DSLR works well; haven't tried Canon. I guess operating systems are something of a personal preference issue and they all have their pros and cons.
  5. Well, there are a lot of things that just work in linux too. Speaking as a person who uses computers to get stuff done but doesn't enjoy trying to iron out issues I find linux more productive overall for me. Try installing a recent linux desktop, such as Ubuntu, and a fresh copy of Windows 10 on a new computer from scratch and you might have a different outlook on which comes the closest to just working. In the old days linux had a lot more problems but I suspect it now works out of the box much better than WIndows. The reason Windows has an "easy" reputation now is that the new computer almost always comes with Windows already installed for you. Granted there will be the occasional new device which needs a special driver and for which the manufacturer hands you a Windows driver but doesn't have one for linux, but it is getting rarer. I would also cast a vote in favor of a getting started with Kstars/ekos thread, thanks.
  6. Just ordered one on Friday with similar reasoning: planetary and can be guide camera if I ever take the plunge to a more expensive, cooled camera. Would be happy to hear your thoughts when it arrives. Mine is back ordered right now.
  7. OK, just wondering because that's a fantastic nebula image with no narrowband filters.
  8. Beautiful image, thanks for posting. You must have some dark skies out your way?
  9. I've heard that narrow band rgb can achieve a lot of the same benefits as adc, but since you already have adc I wouldn't expect any improvement from this effect. I'm trying to find out more about this - apparently the rgb filters need to be fairly narrow band for this effect to be significant. The usual rgb astro filters, I believe, are fairly wide band.
  10. Hard to believe that was a single shot. OK with me if we turn off those city lights.
  11. Nice, you captured some of the details in the arms.
  12. Thanks, olly and vlaiv, this makes sense and seems logical. I think what confused me most is one site where (I can't remember which one now) it was claimed that stacking would align the stars but not fuzzy things like nebula or galaxies, so even short subs would not help for those images. But this seems like it would mean the alignment software moved each individual star and not the whole frame to match the previous frames, which doesn't make sense to me.
  13. I was wondering if differential flexure is important if one usually takes relatively short subs. To be more specific, if a setup exhibits differential flexure problems over an hour or so, but for a 5 minute sub the effects are not visible in the images (tight, circular stars), can the flexure problems be ignored for the case of stacking lots of the short images? In googling this I've only managed to confuse myself as the answer seems to be yes and no. Thanks for any help you can provide.
