Trifid Nebula .... without Hermentaria

An attempt at the Trifid over two nights. 31x20 minute subs with a QHY8 and an RC8 on an EQ6.

During the first night I noticed a bizarre elongated "star" creeping across the nebula over subsequent exposures (at bottom right of attached crop of one sub). Turned out to be the asteroid Hermentaria, according to Cartes du Ciel. Largely disappeared in stacking thankfully, as it was quite bright (mag 10.8 apparently).

The perils of imaging near the ecliptic I guess - on the second night there was a similar fainter asteroid nearer the edge of the frame. Though I've never knowingly encountered that problem before!

Was hoping to get more detail of the neb than my last attempt a few years ago and also the jet. I think, with an optimistic eye, the jet may be just visible.

Comments appreciated. Full res on Astrobin or more browser friendly here.
