I recently built a new computer and it is running Ubuntu 18.04. I installed a copy of PixInsight and updates. Was able to get PixInsight working.
First processing run, I found that I could not register the images. I ran the Batch Preprocesing Script and then StarAlign on the calibrated images. Either would register: batch script registered none and StarAlign like 6 out of 58. Using Blink the subs are good and only movement is the dithering.
I was able to use my old Win10 computer and that PixInsight version was able to calibrate and register the images no problem.
Any reason why a fresh Linux install would not StarAlign?
Thanks,
Steven
