  1. Hi, Am after a Nexus DSC (ideally Pro version) and/or encoders suitable for same and mounting on a Dobsonian mount.
  2. Hi all, So I'm now the proud (and sore - it's heavy!) owner of an OOUK VX16 400mm Dobsonian, and am now learning how to use it and figuring out all the things I need to add on to make it really usable in my environment - but would appreciate some advice from other Dob owners! I managed to get a first light tonight - lots of cloud about so it was a bit hit and miss but I managed to collimate fairly well and look at some bright stars. Defocused, tube currents were very, very obvious - I'd kept it outside in a shed for half the day but it was still clearly a bit warm (the back of the mi
  3. It really is I came in at the start of the Pentium era, though had a fair bit of time on Amstrad and friends prior, but no coding. i386 was my first chip - we've come a long way! If shipping all the image data around wasn't so prohibitive for most people I think there'd be a huge case for a render-farm style service for PixInsight and others; it's bursty, not something all users do all at once, so quite well suited to workload sharing. I did toy with the idea of using an AWS virtual desktop instance for PI (pay by the hour when you need it), but since I did my last PC upgrade I've not n
  4. True. The latest PI release with the quick subframe previewing has helped a lot in my workflow for that sort of thing, particularly noise reduction - but things like TGVDenoise, MureDenoise, and Deconvolution are still very processor intensive with poor previewability (and in the case of deconv particularly a lot of trial and error required on most images).
  5. It's actually not quite as good - the platform doesn't extend far enough to fully support the base! It's a 3-in-one so you can lie it down and use it as a platform, and it has some other weird configurations I've not played with yet. 16" is quite a lot to lug around as one person, especially in a very non-flat garden, but I managed to set up a base for it with some spare paving stones and park it in the shed without dropping anything - I think a Telegizmos 365 cover is in this scope's future so it can sit out most of the time. That's an absolute beauty. Congratulations - that im
  6. Yep - I normally just have KStars sat on the graph view so I can keep an eye on things. Once I've finished writing this Rust INDI lib I'm hacking away at (or give up and fix some of the pure-Python ones) I do want to hook up a watchdog program that can alert me if imaging or the mount stops - I've had one too many kstars crashes on overnight imaging sessions!
  7. FWIW, I'd consider myself PixInsight competent/familiar and WBPP confused the hell out of me - it relies on a lot of stuff in filenames etc which is pretty unobvious and the documentation isn't great! I'd strongly recommend starting out with the Inside PixInsight book and/or doing manual processing to get started. It'll be slower and less straightforward but it's a much easier way to learn the software than running straight into WBPP, in my view.
  8. Quite likely, yep. For what it's worth I use KStars on a Pi remotely via VNC and it's plenty quick enough in my experience (I actually run VNC'd into a Pi4 sat in the house which is running KStars, with INDI running on another Pi4 which is strapped to the back of the telescope). This is with everything wired through a good 1Gbps network, though!
  9. Yeah, excellent point - full frame I would argue demands a pretty high-end PC, realistically. Technically so long as you've got a reasonable amount of RAM you can get away with a lot, but practically it's really painful. I've got some images off a Nikon Z6 which is 6048x4024 natively and I think if I were doing an awful lot of that, I'd be looking at something Threadripper based with 64G or more RAM, especially for mosaics! The ASI183MM I'm using today is reasonably high resolution but since it's monochrome the resulting files aren't huge, and once you've got an LRGB master set the processing
  10. You should be able to set this up on the imaging sequence by selecting upload to remote only and inputting the path there or in the camera settings under the Options tab, at least on recent-ish KStars. If you've got a reasonably fast (wired) network then you'll likely find it doesn't win you that much performance - I think KStars will still pull the image down from the remote end in order to show it and do any analysis (e.g. HFR for automatic focus triggers), so saving it locally isn't a big overhead.
  11. The bats are decorative (we've got pipistrelles living in the outside of the house, so thematically accurate) and the BBC Club sign was rescued from Television Centre before it closed for good Definitely looking forward to first light - which looks like it might be this evening, if I'm lucky!
  12. Alright, so the postman didn't bring this, I had to go get it myself - but still worth a post I think! OOUK VX16 from @Commanderfish now being checked over, tweaked, and roughly collimated after a 2h drive up. Bit of play in the focuser to sort and the mirror cell wants a fan fitting, but otherwise good to go and a superb "little" scope I'm looking forward to trying out!
  13. If you're on Uist then some friends up the north end of things have good internet - up on Berneray. BT did FTTC to the islands as part of their government-funded builds (though failed to actually connect it up till a few competitors started pointing out they hadn't actually delivered anything to people), but there's also a lot of fixed wireless stuff back to the mainland which is pretty quick! http://sealview.com/gettinghere.html Last time I was up there I wasn't really doing astro stuff, but knowing how populous it is (my friend had to go to Lewis to do their driving test because it
  14. Do they work well in darkness without IR? I've got a fair few Reolinks and they're practically useless with their IR switched off, even if the manual exposure is maxed out.
  15. Try this: sudo systemctl disable gpsd.sock To explain a little more - both gpsd.service and gpsd.sock are things provided by gpsd to systemd, which will ensure that all the dependencies for the service/socket are met. That includes, if you just disable the service, bringing it back to ensure the socket is available. If it's still booting up then try systemctl list-dependencies --reverse gpsd.service - this will tell you what is dependent on it and bringing it up.
