Ok so my initial thought is this was a starlink train... BUT I have captured a starlink train before and it did NOT look like this.
That is the link to the video file i created using PixInsight.
things to note here... this is with a WO RedCat51 with an ASI 294MM
there are 4 total frames.
each frame was 5 MINUTES long so a total of 20 minutes for these objects to pass by
this is my green filter imaging the Horsehead/Flame nebula
