I hope someone can help me as I am stumped.  I have a Starlight Xpress SX674 camera which earlier this year was working fine.  However, I had to take a break from things and have now come to set everything back up again and have been testing everything to make sure on the next clear night I can get going again.  

Unfortunately the something to do with the data transfer from the camera is causing issues.  If I connect it via my Pegasus PowerBox Advance I get a small artefact around 2/3's of the way down the frame as per the first picture.  If I connect it directly to my Pi4 things are much worse and I get the second image.  I have also tried NINA on my PC and it works fine as per the third image.  I have tried everything; different USB cables, all the different ports, I have completely wiped Astroberry and re-flashed the SD card and have even tried a different Pi4 and the result is the same which leads to me to suspect it is a driver or other software issue.

My Altair Astro 130M works just fine as does my Sony RX10M4.  It is only the SX674 which is causing issues.

Note the fourth image is just a bunch of stacked frames so you can more clearly see the artefact.

Has anyone got any ideas at all?

Any help would be hugely appreciated sx1.jpg sx2.jpg
