May 2020 AP Challenge No. 1 - The Blackeye Galaxy

#1

Post by Gordon »


For the month of May our challenge will to be to attempt to process the linked data. Post your completed image along with the softwares and steps used to process. Again this is not a contest. So just give it your best shot. Others can comment and make suggestions to help our beginner AP's get the hang of how to process images.

Thanks to member Jockinireland (David) for submitting our first challenge data!!

Here's the information on the image:

The Blackeye Galaxy M64
8" LX200 GPS on a Wedge
EOS1100D unmodded
Guided in PHD2
89 X 180s ISO800
Stacked in APP with full set of calibration frames.

This image has some nasty coma and field curvature out at the edges but seems to have nice detail in the galaxy and especially the core.

Here's mine!

Opened in Gimp selecting Imaging Composing Naxix=3. Dunno what that means but the default opens a fits file in grey shades.
Stretched the image in Curves and adjusted the black point in Levels three times. The third stretch didn't allow a black point move and I had to adjust the mid point to get some more black in the background.
Cropped to centre the Galaxy.
Then I added a subtraction layer and attempted to remove the gradient with the gradient tool. Worked a bit but it's not perfect.
The Clone tool removed the red and blue hot pixels after I found out it wasn't working because I had the gradient layer selected!
Sharpened with unsharp mask.
Tweaked up the saturation.
Tweaked a slight S curve.

The galaxy outsides look a bit over processed and the background is a bit too dark for my taste but if I lighten it the red in the top right corner becomes too obvious!

Thanks for the data David.

Graeme,

That looks great for a GIMP processed image! I still need to find time to play with Davids data. I want to run it through StarTools and see what I can do with it.

OK,my try. Did a sharpening of the center and contrasts enhancement with Carboni tools and stacked this and a smoothed deeper image in PS by a layer masking method. Cropped to fit better, this eliminates the edge effects that don't really matter anyway.

Given the image a try in star tools.
Processing is not my strong suite!

Basic rundown.
Bin 50%
Crop
Wipe , gradients and vignetting.
Stretch 93%
HDR
Final noise reduction
shrink
I am not always happy with the colour module so I left the colour as is.
My question is this, how do you get rid of the hot pixels with star tools? Once I get that done I can better process this image, I think.

You can use the "Heal" tool and select the hot pixels to remove them.

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 calibrated DSS export. Should that process not have removed the hot pixels?

Either way, I gained knowledge of the clone tool getting rid of them!

Hi there, I'm really not sure what those are - you are right though that the consistent shape throughout the image suggests something other than straight hot pixels. Then again I have seen something like that before but bigger, when I was not guiding and put it down to the hot pixel moving when the image was stacked. Today I will look at some individual frames and see in there are hot pixels showing in those locations.

I am not expert with APP and I know its possible to tweak settings to better remove hot pixels - maybe I need to look more at that.

Also, these were stacked in APP with 40 each Flats and dark flats, 100 Darks and 200 bias. The large numbers of darks and bias were because I'm scaling the darks and dark flats within APP (I've only done it a couple of times) and the word is that to do that you want to use large numbers of darks if you do that. They were fairly closely matched for temp (+/- a degree or too), matched for ISO 800 but the darks were 300s. I got advice from the APP forum that that should be well ok. But now I'm wondering if there is something going on with that.

Any ideas anyone?

I'm going to go back now and have another go at my one because there are a few things I've seen above that may help with my version.

This is a really great way for me and others to learn.

Without a doubt!

I look forward to seeing what you come up with on your darks investigation. Would the variance in exposure times be the culprit?

Possibly but I don't think so. I was told that APP is able to handle that type of scaling, so long as you include bias frames and that scaling down, i.e. using longer times for the darks is best. But I'll get the old Sherlock Holmes Deer Stalker hat on and dig into it.

Another try at this.
Thank you to Gordon for the healing tool suggestion.

First up is a zoomed in image of the "hot" pixels. Hope it helps determine what they are, you can see both the red and blue in this image.

Thank you to Gordon for the healing tool suggestion.

First up is a zoomed in image of the "hot" pixels. Hope it helps determine what they are, you can see both the red and blue in this image.

And now my revised version along with the star tools workflow log. I have cropped this image more than my previous version.

Hi Clinton, that looks really good. You've got rid of the noise I got on the outer areas of the galaxy. A d I love the colour and the softer detail of the core.

Looking at your workflow I see that you have used develop instead of auto dev. And I dont see the colour module. Does that mean that if you use dev you dont need to use colour?

Thanks David.
I don't like the auto dev., I prefer develop on it's own.
I also do not like what the colour module is doing to the colours, so I skipped that and left the colour as is after stretching.
The noise is not bad at all and I was able to give it a good stretch before it showed up.

I must give that a try because i do like the output and the colour is pretty much where i got to after the colour module.
