Re: May 2020 AP Challenge
Something else I have noticed is that your image has star colour whereas mine they are all white.
I should have masked them sooner, might have to give it another bash.

Re: May 2020 AP Challenge
Right, so here is the result of my sleuthing on those hot pixels/artifactsGraeme1858 wrote: ↑Sun May 03, 2020 6:03 am
I wondered if those artefacts are hot pixels? They're all the same shape and orientation, reds and blues, two blobs, one bigger than the other and the fits file is a stacked and calibratedDSS export. Should that process not have removed the hot pixels?
Either way, I gained knowledge of the clone tool getting rid of them!

Images;
Single light frame Zoomed in on the light frame anomaly Single dark frame (same image location) Zoomed in on the single dark frame Stacked file Zoomed on stacked file. So its pretty clear those bright spots are mostly 3X3 groups of pixels visible in both lights and darks. Now I am not technical enough to know if this is a normal hot pixel type (i.e. 3x3 pixels or if this is something else - anyone?)The smeared out view in the stacked version is clearly because my tracking/guiding has been off and therefore the hot pixels have moved relative to the image.
What I dont get is why
I'm currently running the same data through

Re: May 2020 AP Challenge
OK, so after what feels like an eternity I've got the output from DSS . opened, stretched and background neutralised in APP to see the difference.
And indeed the hotpixels are gone. Vanished. Like they were never there!
Stacked inAPP
Stacked in DSS
Apart from the hot pixels there is not really much to draw between them i think.
So, Now I need to work out whyAPP failed on those hot pixels. Or go back to using DSS .
I will put theDSS stack in the same Drive folder as the original if anyone wants to see what its like.

Re: May 2020 AP Challenge
I typically start out with 'Autodev' just to see what I'm dealing with. It's not a permanent stretch so you can revert back at any time. Autodev can give you better detail on where the image has to be cropped if you are trying to save as much of the image as possible. In this case it was easy to crop it down to center and isolate the galaxy.
I very seldom mess with the colors. ST does a great job from the get go.
As to the hot pixelsDSS has a setting to remove them. It appears that there are a few and if you zoom in you can see how the stacking process 'stacked' them. [mention]Jockinireland[/mention] Take a look at DSS and click on the 'remove hot pixels' box. It appears from your last image, you figured that out!

Re: May 2020 AP Challenge
OK, so here is my new effort after taking looking and reading the above.
Less noise, less in your face sharpening of the core, nicer colour (I think)
Startools work flow as follows;
Type of Data: Linear and was Bayered, but not whitebalanced
--- Auto Develop
Parameter [Ignore Fine Detail <] set to [Off]
Parameter [Outside RoI Influence] set to [15 %]
Parameter [RoI X1] set to [0 pixels]
Parameter [RoI Y1] set to [0 pixels]
Parameter [RoI X2] set to [4278 pixels (-0)]
Parameter [RoI Y2] set to [2864 pixels (-0)]
Parameter [Detector Gamma] set to [1.00]
*** Like Jim (Juno16) I cannot get my whoe workflow in here - after the above the font turns red and huge. So I have put the workflow in the file where you got the data as a word document***

Re: May 2020 AP Challenge
It's a problem with the 'coding' in the ST log. We have a BBcode for using 'shadow' text. The log uses the word shadow with a bracket in front if it. I found if you edit each instance of the word shadow with a period (shadow.) the problem goes away.Jockinireland wrote: ↑Sun May 03, 2020 6:27 pm *** Like Jim (Juno16) I cannot get my whoe workflow in here - after the above the font turns red and huge.

I took a crack with StarTools with an eye towards exposing the outer areas of the galaxy:
General process:
Autodev (no ROI)
Crop - to remove most of the gradients
Bin to 71%
Wipe
AutoDev with ROI
HDR
Deconvolution
Color

Noise reduction (turn off tracking)
Repair to remove the hot pixels
Then a quick trip to PhotoShop to do a little Noise Ninja reduction and convert to .jpg.

That is a really great process. The way you have managed to get the outer limits of the galaxy showing but without any grain while also retaining the detail in the core is just fantastic.

Re: May 2020 AP Challenge
Here's my 2¢ adjusted for the cosmic inflation...
I did very little processing to this image really. Compared to some I've worked on, this wasn't too bad.
Cropped it down a bit
I used the clone stamp to remove the red and blue pixels.
Automatic background extraction for the gradients. (Division with no normalization applied).
Made a star mask to try to get some color from the stars, but they are pretty much saturated.
Made a range mask for the galaxy and used both local histogram equalization and HDR Multiscale transform to bring out the dust lanes and black eye areas.
Adjusted curves and levels to get a pleasing color balance.
Saved as jpeg for posting.
Pixinsight has a few nice methods for coaxing details out...
thanks for the data!
Cheers!

Re: May 2020 AP Challenge
The Global redo module brings out a lot of the outer limits. Decon and sharpen bring out some of the detail in the core. In the HDR module there is a setting called "reveal" that enhanced the core detail. The Denoise module in Star tools version 1.6 really works nicely to get rid of grain and noise.Jockinireland wrote: ↑Mon May 11, 2020 9:12 pmThat is a really great process. The way you have managed to get the outer limits of the galaxy showing but without any grain while also retaining the detail in the core is just fantastic. How have you achieved that?jerrysykes wrote: ↑Mon May 11, 2020 7:38 pm Here is my attempt at processing using Star Tools 1.6.382 Alpha.
Autodev
Crop
Bin 50%
Wipe
Global redo (Dev)
Decon
Sharpen
HDR
Color
Denoise
Repair
Heal (to get rid of hot pixels)

Hope this helps. I tried to post the entire work flow but I just couldn't make it work.

Thanks for that. It ooks like the only thing I've done different is to use autodev after wipe instead of dev - i'll give it go and see if I can get it as good.
I had problems with copying the full work flow and Gordon told me;
"It's a problem with the 'coding' in the ST log. We have a BBcode for using 'shadow' text. The log uses the word shadow with a bracket in front if it. I found if you edit each instance of the word shadow with a period (shadow.) the problem goes away."
I've not tried it yet though!
