Cheers Troy
I usually do a straight RGB and blend it with the narrowband data until I like the colour of the stars, I recon they kinda need to match the palette of the NB rather than what I would use for an all RGB/LRGB version or what some guys like and that's all white but that's just personal preference. I then blend just the stars into the narrowband data, this can be tricky and the star sizes need to match and the registration needs to be good. If you look carefully I haven't nailed the registration perfectly in the bottom right and top left so may need to revisit that aspect but it is not that noticeable, so not a biggy.
I also mix some of the RGB colour into the overall completed narrowband, basically I get several different version going on the boil each with the best aspects and mix'em...like I am making a minestrone

Thanks Marc and yes I think it is the grub screw that tightens the small cog wheel to the worm gear shaft it comes lose, I can't tighten it as the Allan head is rounded so it just slips off once the slew starts...or it could be the worm slipping and...eerr?.. that would be no good and may require some worm block adjustments

never easy trying to trouble shoot at 2am when it is -2C and you are tired though

Hope the gearbox repair goes smoothly.

Thanks Mike..oh and what would you know about having technical issues with a mount and scope, huh?? I mean really

Cheers Terry, glad you like it and I non secularly pray for some more good weather for you

I like Bicolour images and although sometimes they lack depth from the missing tricolour bandwidth, your colour palatte is well chosen, well done sir 
Good luck with the repairs, it's seriously painful when stuff breaks.

Thanks Andy...yes, equipment troubles are very rare for me, my rigs over the years have always been relatively low tech and bullet proof...so I want to fix it asap

There is an informative article by Richard Crisp here http://www.narrowbandimaging.com/synthetic_rgb_page.htm. (Look down the page a bit to see the bicolour info)

Cheers Geoff, I was thinking of waiting until I have real SII but meah I may well give that a go, thanks
