The not insignificant amount of narrowband data doesn't look to be showing up much? At a distance of only 75 Million light years I wouldn't have thought you would lose much from the band width through red shift? What did the Ha stack look like?

Thanks Mike. I agree that the NB has not come through in any significant way, which might be down to the the method I used to incorporate it. This is the approach used: https://www.youtube.com/watch?v=jJFUZY5p6yQ

The NB stack is attached (just a basic auto screen stretch shown here). It may be that the NB signal is simply too low compared with the BB so that the ratio I used (from memory, 0.75xBB+0.25xNB) did not give enough weighting to the NB signal to make an appreciable impact. I might have a play to with the weightings to see if I can improve the result.

Thanks Dave. See above re Ha data

Thanks Alex, lovely comments

Everything has been really well handled.

Nice to see accurate RGB colour....I'm really starting to tire
of weird NB palettes that seems to be fashion trend of late.

Nice one
Thanks Peter, really appreciate your feedback and kind words. Out of curiosity, if I were to take it to the 'next level', I assume I'd need to increase the sampling rate to take advantage of the larger aperture and better seeing? (my sampling with the current setup is bang on 1.00 arcsec/px)

Detail and colour is superb
Great result, you must be pleased

Thanks Martin Yes, i've cropped in here to make NGC1365 the obvious hero of the image. I've included the sensor's full FOV over on Astrobin.
