Starlight Live on Mac 10.15 Catalina?
richardlawler replied to richardlawler's topic in EEVA - Discussion
Sorry, I don't really know what triggered the fix. I was having problems as noted up-topic. And then when I tried to run Starlight Live again at a later date, I was notified of the problem and that it was being repaired. I think it was the result of some sort of integrity checking that Mac OS does automatically. -

Fixed: Mac OS reported a damaged file having to do with the Starlight Live software stack and repaired it. Since then Starlight Live has been working on Catalina. Yay! -
richardlawler started following EAA post-processing and Starlight Live on Mac 10.15 Catalina?

I've recently had to upgrade my MacBook Pro to Catalina 10.15. I find that Starlight Live 3.3 and 3.4 just crash on launch. I am trying to use it with my Starlight Xpress Ultrastar C. Has anyone had any success using Starlight Live on Catalina?

Have you tried Starlight Live? I believe it uses a whole different driver. You can download v. 3.3 from the Starlight Xpress site. https://www.sxccd.com/ultrastar-and-ultrastar-c

Thanks Paul. I forgot that with the 3.3 exposure control I can now go down to 1ms. I guess darks encapsulate bias as long as the exposure is the same as the light frames. So I should be good if I standardize on an exposure time for most of my images (as AKB suggests above) and the temperature doesn't vary too much. Flat fields might still be helpful, depending on the optics. But a few experiments with various optical configurations should determine if there's anything to gain. In spite of my desire to post-process, I'm really trying to keep it simple. I've learned the hard way

Thanks, that's exactly the sort of information and experience I'm looking for. I've been trying out Nebulosity, and it looks like it can do the sorts of things I want to do "the morning after" with the FITS files captured from Starlight Live. I can't get Nebulosity 4 to see the Ultrastar C camera from the Mac. (I've not tried it on a PC.) I don't know if that's a bug or just a gap in the supported cameras. But it's probably not necessary with Starlight Live doing the image and dark frame capture. Although Starlight Live doesn't capture bias or light frames AFAIK.

And this command too: open -a StarlightLive --args -load-image-rggb ~/Pictures/Astro\ Photos/Bodes_35x15s_median_2017.4.21_09.25.28.fit Note the full path and file name are required for the image file.

Update: I found this command worked: /Applications/StarlightLive.app/Contents/MacOS/StarlightLive -load-image-rggb Bodes_17x15s_median_2017.4.21_00.17.34.fit

Hello, all. I acquired an Ultrastar C for EAA last fall. (I only got a few chances to use it over the winter, but we got some desperately needed rain instead. So that's ok.) The Ultrastar C has been astounding on the few evenings where the fates have yielded to properly working equipment and clear skies. I'm looking for pointers to tools and techniques for post-processing the color FITs image stacks captured from Starlight Live. I'm on a Mac so that limits some of the software options available. The docs for Starlight Live say there is a command line option ('-load-image-r
