Hi everyone, ​I am getting an error message while trying to run the SpectroPhotometric Color Calibration (SPCC) tool in Siril. The process halts and displays the message: "Catalogue error: no stars identified". ​I have already downloaded the required astrometric and photometric star catalogues to my local computer. Specifically, I have downloaded all the data tracks visible from my location here in Italy (omitting only the Magellanic Clouds). ​This is the first time I have encountered this issue since I started using Siril, and it has previously always worked without a hitch on my other images. ​Could anyone help me understand what might be causing this error and how I can go about fixing it? ​Thanks in advance for your help!

@jinouss you could try this out since you are good at Siril processing,@DILCHSKY ,@StuartTheAlien👽🖖 in case you didn't already try this target with your telescopes The reason? Simply because using a external battery will give the Seestar enough energy to shoot for the whole night instead of only 3-4 hours. After gathering as much light as possible, stack separately each of the panels in Siril or the app, and no matter what your astrophotography skill level is, do your best to process them with any astro software like Siril, PixInsight, GraXpert, Cosmic Clarity, Astroforge etc. After that, assemble your 6 panels with Microsoft ICE, PixInsight, Google Photos if you don't care about anything, or any other software you like.

哪位大佬能教我后期剪辑，搞不懂延时摄影。 Who can teach me post-production editing? I don’t understand time-lapse photography.

When "Save Each Image" is enabled, the Seestar currently saves both the FITS file and a JPEG version (plus its thumbnail) for every frame.For users who perform their own post-processing, the FITS files are usually the only files that matter. In my case, I routinely delete all the JPEGs immediately after copying the data to my computer.It could be useful to add a small option next to "Save Each Image" allowing users to choose what to save:☐ FITS + JPEG (current behavior)☐ FITS onlyThis would reduce storage usage on both the device and the mobile device, especially during long imaging sessions where hundreds or thousands of frames are collected.The current behavior would remain the default, while advanced users who only need the scientific data could save considerable storage space.

Happy Summer Solstice (tomorrow)! Neolithic peoples and other ancient cultures celebrated the solstice for many reasons, mostly agrarian. Some worshipped the sun, some used it to mark the time between planting and harvest, some marked it as a new year. But we northern Astrophotographers celebrate for a slightly different reason. Here we mark it as the turning point. We have made it through the long days, and short nights! Every night from here on gets longer and darker (for some). Congratulations to my northern hemisphere brothers and sisters! To my southern friends- I’m sorry 😂 Clear skies!

I will be attending the Astronomical League Comvention in Cincinnati, USA Aug 12-16. If anyone else is also attending, it would be nice to meet you!
