I have no idea what they are; the fact that they are all orientated in the same direction told me that they weren't galaxies, and had to be artefacts
within the optical train. I thought I'd have a bit of fun, most of us would
know that there is no galaxy group anywhere near that area.
Could be a little bit of dew on the camera sensor or the scope's mirrors,
or a bit of wispy very light cloud. My collimation is pretty good.
It didn't appear on my other images that night, so I suspect cloud could
be the culprit. I just remembered that M57 got dimmer frame by frame, so I think
it must be cloud.
