Hey all,

I had first light on my SkyWatcher 300 f/4.9 and I noticed that the stars are looking kinda wonky. I made sure to collimate it after my first few images, and the primary and secondary seemed in line, but it looks like the stars are skewing to the right. Especially on the OAG (although it was still tracking at around 0.44", which to me seemed great). So I'm wondering what could cause this? Is it:

-Focuser tilt?
-Secondary mirror tilt?
-Tube currents?
-Bad corrector?
-Tube flex?

I've added photos of the full field around Achernar, a close up of the surrounding stars, what the guide camera is seeing, Achernar out of focus, and a 5 minute exposure of the Tarantula Nebula.

Thanks in advance!
