Would you please be able to publish some small pics
of separate RGB frames for your Eta Carinae?
I would especially like to see a blue frame.
OK...I've done better than that.
This is a link to a mouse-over of the blue versus H-alpha channel data, complete with spelling errors
As you will see H-alpha (a very deep, but visible red which DSLR's are quite insenstive to) dominates, with many features simply not emitting in blue at all.

Thanks for that Peter,
I can see that the blue is no where near as strong as the red.
It would be interesting to see a different processing with
equal RGB colour graphs using curves in Photoshop -
in other words artifically balanced.
Oh I do like the field of view and the star sizes are sublime. Like pinpoints. Not keen on the main nebula though. Lacks punch to me, but each to their own.
Now show me somthing like that NGC3576 finished. Please.

Appreciate your frank comments Paul.
If by punch you mean: some sort of sharpening... decided to keep it "au naturel ". As you say, dealers choice. But I might fiddle at the edges at tad.
I wont bore interested viewers by heralding the changes, they'll just happen from time to time.
Another object!? What? move away from the program??
Yes, I think it's time to move on. 3576 I've decided looks poor in wide field NB. RGB seems to be the go
As for when...Did I mention the forecast again today???
Recently I entered an informal partnership with Dean Salman who has a remotely operated observatory with a 20cm F4 Maksutov Newtonian about 50 miles from Tucson Arizona. Dean is going to allow me to use the observatory about 2-3 times a week and in return I am to provide him with some data on selected southern objects. Dean’s main speciality is the Sharpless catalog and he has a web site of his Sharpless images here:
I’ve been taking some images for a few nights now and here are the preliminary results. The camera is a QSI 583 WSG. All the images are black and white at the moment but some colour should follow soon.
M101. This has always been one of my favourite galaxies. The image is a 60 minute luminance shot taken under fairly bright moonlight.
PuWe1 is an incredibly faint and large planetary nebula in Lynx only discovered in 1980. It has a diameter of about 20’. This image is 5 hours 20 minutes Hydrogen Alpha.
Hi Peter,
I hope you don't mind ?
I took a small crop of your photo &
adjusted it to give more blue & less red.
It's only a tiny jpg.
What do you think?
I like the effect of the different coloured areas.

(Thanks! 
Remembering it's from the corner of the frame too - it's amazing!
