Pixel mining IC4628

[Peter Ward]

PixinSight's weird user interface, I suspect is causing me to drink more than usual...yet the unexpected results it delivers, simply stagger me (perhaps in too many ways )

So now I find myself going over old data that until now, hadn't presented well.

I simply needed better processing tools....with Pix being one of them.

An example of what I'm on about is linked below:

P.S.
Clearly substance abuse was going on during data capture, as I decided fishing line, placed in front of a sublime AP objective, was a good idea at the time

so Mr Ward I take it you are liking PI? do you have the before processed shot to compare?

Yes...and err, yes.

GReeeaat! so where is it?

[LewisM]

So which PI routines did you use Peter?

Fishing line diffraction spikes... ACK!!! Substance abuse indeed...reckon you drank a little avtur with your scotch

Lovely lobster Peter ! I would prefer it without spikes, but as usual that a strick matter of personal taste (and I also add spikes time to time to some objects )

Great details and dynamic range. Very sharp in the core area. Nicely done.

Thanks for the feedback guys... For David... old version here

I still finding my way with PI, hence my processing is still scatter-gun, but I have found HDRmultiscale transform/ wavelets, masking and noise reduction to be very useful .

Massive difference with that data, not even chalk and cheese. I note the stars are tighter and smaller, the patterns and structures of the gas clouds are well defined and you have achieved a darker background whilst maintaining and increasing the gas cloud brightness. Impressed with what a difference PI makes…..

Looking at both side by side now I like the details in the repro but just realised its dynamic range is all scrwed up, like HDR gone wrong. Maybe a compromise in between is the way to go. Details + correct luminosity.

Yep, I still need to get a better handle on PI.

.....as David would say: "respect the light".

Bah! I can do that kind of thing in PS - piece of cake! AND I don't need therapy afterwards because the PI interface induced uncontrollable facial ticks. The question is, do I want images to look like that?

Agree with Marc. I can see why it might have mass appeal, but it's a tad overdone for me, especially if you're trying to achieve something resembling "correct" tonal relativities. Somewhere between the two might be the go to avoid the typical hyper-contrasty PI look.

Cheers, Marcus

I have a tic!? What itc? But Marcus, don't be too hasty, wait till you see the Las Vegas neon colour version

That's the reason why your repro piccies are turning out so much better... the drink You're feeling loose and not so uptight, plus, the mojo is flowing

See what good software can do for you

Yeah baby !

Overcooked IMHO - too contrasty and the wispy details at the edges of the nebulosity are lost. PI's a definite learning curve - I'm waiting for another tutorial session with Rick! Something to satisfy one's astronomy needs during the monsoon season.

Was wondering what you'd done to create the diffraction spikes - you should be forced to give up your scope for such sacrilegious behaviour!

Fair 'nuff. Frank and fearless. I like that!

Well...at least they were physical diffraction spikes...and not the Photoshop variety.
