Thanks for the comments Mike, Marc and Mike.

Yeah, the colour is problematic, its soooo.. much easier working with single strong monochrome data. I need to find a suitable workflow for the colour data but that's what forums are for, right?

The Ha data came out nice. The others, not so much.... a much weaker signal. I often wonder whether I should bin the SII and OIII (something to try in the future). However, the biggest problem lies in combining the data, most of the tutorials I've seen are based around DSLR and OSC. I think I need to rethink the earlier workflow. The registering and stacking of each data set seems to be OK the later stuff is a bit of a mystery. Any suggestions are more than welcome.

The combined data image looks ok but the cyan in the bright parts is overexposed and looks wrong. I don't have a diffinitive suggested fix as NB imaging is so much like ..?..cooking a bolognese sauce, bit o this bit o that.. just have another go mate
How would you quantify the guiding quality of the SX AO? Is it easy to use?

Thanks Mike,
In the crystal ball, I see a (dare I say it....) Sidornio is in my immediate future! This is the first time I tried normalising the intensity of each stacked SII, OIII and Ha data set before combining. Is this the accepted protocol? Also, do you start stretching the data for each filter before combining or stretch the image after combining? Probably pretty basic questions but....
The cyan areas would be the OIII data overcooked, but also the Ha being too bright as well. I'll have to take it right back I think and see whether the normalising is doing something untoward.
As for the SX-AO, I really like it now (bloody expensive guide cam
). A couple of things annoy me but I think there are fixes around. An its getting easier to use as I become more familiar with it. With a good strong guide star it performs
and the lodestar has binning to help in this regard. It does seem rather cloud sensitive though. The HEQ5pro is too light for my latest acquisition (RC8 - which is why I bought the AO in the first place) but performs well with the 127ED. The crystal ball is predicting a new mount
and probably a trip to the Gold Coast too
.
This an expensive hobby.
