Meteor composite image production?

[michaelmorris]

I have two Watec 902 video cameras recording meteors every night.  I've been experimenting with making meteor trail composites from the peak hold  .jpgs produced the UFO Capture software I use. That is, a composite image made up of all the meteors trails recorded on a night or month. So far I've found two similar ways do doing this basic composite production.

1 - Photoshop. Import each jpg as a separate layer and set the blending mode to lighten.
2 - Use star trail production software such a Startrails ( www.startrails.de) to do exactly the same as 1, but much more quickly (and it's free).

This produces a pretty end result, but because the sky rotates between images, it doesn't tell a story. Ideally I want the software to read the alignment automatically align the stars in the image so that shower radiants become obvious.
So far I've only found two ways of doing this.

1 - there appears to be a tool called 'Panorama' in 'Metrec' software that does this, but as I can't use Metrec (you need a specific discontinued model of Matrox  video card) this option is closed to me.
2 - manually align each image in Photoshop ( http://www.davidkingham.com/blog/2013/4 ... ower-image) . With 99 meteors recorded on one night alone (Perseid peak) this is a non-starter.

Does anyone know of any other software/ methods for producing a star aligned meteor composite?

Thanks

Could you register the frames in DSS without stacking them, then you could layer them with already aligned stars using lighten mode in Photoshop?

With dithering turned off I would have thought DSS would keep the trails in the final image. It certainly does a good job of keeping them when I don't want them!
