  1. Decoding the CYGM (Cyan, Yellow, Magenta, Green) colour matrix of the Lodestar to RGB colour space is actually quite tricky. I had several revisions of the algorithm and bias it towards astronomical imaging as opposed to natural daylight colour reproduction. Paul
  2. Starlight Live has a dark frame mode to capture darks (which are not applied to any of the raw image FITS files - only to the live stack). You can capture a bias with a 1ms exposure (but the bias is reasonably well contained in the dark) and you can capture flat frames by following the same as image capture but turn off live stacking.
  3. This is a good idea and shouldn't be to hard to implement. I have raised Issue #17 to document adding this as a new feature. Haha - yeah I've seen that one a few times now :-)
  4. Superb comparison - this was one of my main aims with the FITS export to allow people to play with the data in a full-fat image processing application when the clouds have rolled in. I would always expect expert post processing could pull out more detail as there are limits of what you can do on the fly. On the sharpening and de-noise front, I prototyped a wavelet based algorithm for SL at the tail end of last year and it works quite well and can make quite a remarkable difference. So this is something to look forward to in V4. Its a bigger change than anticipated as i realised i needed t
  5. You are welcome - I'm always glad to see it's useful and opening up more of the sky to people!
  6. Really like the animation - shows the dynamic nature of the comet! Great stuff!
  7. Wow - outstanding! Hyperstar is proving to be spot on for EAA! Always glad to see the software proving to be useful! I haven't had much time to work on it recently - I must look into the OSX bug with the image repeat so you can upgrade to the latest versions :-)
  8. Thanks chaps! Was pretty cool to read about SL in Astronomy Now :-) I haven't been able to dedicate anytime to SL recently due to work and moving house but pretty much sorted now so can get back to business very soon :-)
  9. Spot on guide, certainly makes it easier! With regards to the high DPI display command line argument, I have a test build that should hopefully mean this is no longer required. Do you have a high res display? If so would be able to try it without the command line argument? The test build is available to download: StarlightLive.win32.BETA-3.4-TEST-BUILD-170131.zip Cheers Paul
  10. It's only SX filter wheels, should work with all USB models!
  11. Hi Paul I think the issue you noticed is the same root cause as issue #11 on the bug tracker (https://bitbucket.org/Paul81/starlightlive/issues/11/v32-remote-image-window-zoom) - I was planning on looking into this one quiet evening as I don't have a second monitor for my Mac but I'm hoping I can replicate it when plugged into a TV - in theory it should be the same...! out of curiosity, does the display come back if you modify one of the display settings (which forces a redraw) - say tweak the histogram stretch? Paul
  12. Hi all, StarlightLive V3.3 is now available to download: OSX: https://bitbucket.org/Paul81/starlightlive-downloads/downloads/StarlightLive.osx.3.3.zip Win32: https://bitbucket.org/Paul81/starlightlive-downloads/downloads/StarlightLive.win32.3.3.zip Bug fixes and some feature updates - from the README: - Image display processing and stacking performance (speed) enhancements. - Added option on the settings tab to select night mode which modifies the user interface to use a subdued dark room theme. A separate option also allows the main image display to be rendered in l
  13. There is a new test build update which fixes issue #13 - the colour channels separated on the histogram display when applying stretch with auto align enabled. Hopefully this is the last beta and then will release this as the official V3.3. Download links on the wiki page: https://bitbucket.org/Paul81/starlightlive/wiki/Home
