G'day all,

 

I took another stab at my Bortle 1 Milky Way core data. I used RawTherapee's post-resize deconvolution for the first time. I was happy enough with the result to post it:

Cheers,

Beautiful golden light, and the nebulae came out well too.

Nice, I can see the blue in the Triffid in the shot.  Really nice.  Super curious what PixInsight can do with that image.  You mind posting the un-processed image?

Nice! I was shooting it last night on my skyguider pro (which I now have installed on a 6" concrete filled pier.  A bit overkill) and newly modded Canon 6Dii and Sigma 28mm lens.  ISO 3200, F4.  30s exposures. 15 min integration time. Polar aligned only with a compass.  Stacked in APP, run through PI and then into Photoshop for the drama!  I was so worked up by my frustrations with my other "proper" rig that I messed up.  Should have tilted down more to get Rho with some more headroom below it.

Thanks!

 

But I cringe at sharing the stack.

 

I chafe at the scraping of our outputs in the forums by anonymous third parties for their own enrichment. For instance, here are my Homunculus Nebula shots earning clicks for some Internet rando:

 

https://assignmentpo...lection-nebula/

 

Besides not being credited, I assure you I receive no royalties from the ads.

 

I will ponder whether and how to share the stack…

I shared some Stacked Unprocessed Data recently. Someone posted a link to an image that had their personal Copyright symbol on it, after processing the Data.

 

I was kind of annoyed, not about the processing, but about the Copyright symbol.

 

I learnt a bit about Copyright after this, and learnt that the Copyright for an image is always retained by the person who actually took the image.

surely you have a right to request the image is removed from those Advertisements BQ ?

Yep, I'm aware that as the title holder (owner) of the data, I am the holder of the original copy rights. But in the Homunculus case in point, it was my own **** fool fault for not watermarking the images. When I posted it, I was naïve and never imagined third parties would be scraping the forums for images. My first inkling was a bloke running his own website about AP who actually asked my permission to use one of my Jupiter red spot animations in an article on Jupiter (with credit). Then I found several revisions of one of my DSO images on astrometry.net, where some presumably good Samaritan was trying to figure out why the system couldn't find a platesolving solution.

 

The rub is two-fold. First, you don't know what you don't know…who knows how many of my pre-2019 images are out there? Fortunately, I don't stay up at night wondering who's profiting off my mistake of posting free candy. Second, once you find one, what outcome do you want? Chasing down a website owner is a real PITA. If the website owner is ethical and the perpetrator was one of their users, then it's just a simple matter of proving the data is yours (the astrometry.net abuse staff immediately removed the offending images). But the website with my Homunculus? I'd be happy to let them use it for image credit. But that site looks quite dodgy—and I don't care to dissect the website governance, find the page owner, and prove to them my image ownership—all just to have them add credit to my nom de guerre.

 

The Internet is still a global wild-wild west. So for me, copyright watermarks in the images are like like the KAPU signs in Hawaii—and I would actually prefer people with derivative works watermark theirs—otherwise, the data scrapers are screwing over two intellectuals' data rights! Technically, when I post data I am granting a license. Derivative works are also intellectual property with ownership and copyright protections. But  those derivative copyright protections derive from the license that was granted with the original data. I can state the license in the post where I share the data, and I can put the license in a text file zipped in with the data. I'm also looking at how to modify the FITS header to add a copyright and a license header entry.

 

My preferred licenses are the Creative Commons licenses used heavily by Wikipedia users. Since credit to the originator is really my only embuggerance, I'll probably go with the CC BY 4.0 attribution license. If someone finds a way to make money off my images, I reckon good onya mate!

BTW, I wrote a script in Python with Astropy to add the copyright and license to the FITS header. Maybe you'll find it useful to watermark your own stacks. Here's my code, licensed to all under Creative Commons Attribution 4.0:

 

# Python w/Astropy script to add header data to a FITS

# ©2023 BQ Octantis

# Released under Creative Commons Attribution International 4.0 license

# https://creativecomm...icenses/by/4.0/

 

print("Loading files...")
import astropy
from astropy.io import fits

 

FITS = "Pictures/_siril/20210731_MW_Core.fit"
OUTFILE = "Pictures/_siril/20210731_MW_Core_hdr.fit"

 

HDR = fits.getheader(FITS)

 

print("Adding headers...")

HDR['targname'] = ('Milky Way Core', 'Capture target')
HDR['cpyright'] = ('BQ Octantis', 'Copyright 2023 BQ Octantis')
HDR['license'] = ('CC BY 4.0 DEED', 'Creative Commons Attribute 4.0 International')
HDR['licinfo'] = ('CC Licenses', 'https://creativecomm...enses/by/4.0/')

 

DATA = fits.getdata(FITS)

 

fits.writeto(OUTFILE, DATA, HDR, overwrite=True)

 

print("Done.")

 

Enjoy!

I've sold a couple of books and a moon print. Not sure if that's commercial.

 

But everyone is a copyrights holder, and it applies to everyone who posts an image anywhere. Astrobin and the CN gallery even make the declaration formal:

 

Screen Shot 2023-10-07 at 8.33.36 AM.png

 

Screen Shot 2023-10-07 at 8.34.34 AM.png

 

Did you not read my Post #11 as to the source of my beef?

 

With this post, I simply invented a way to formally share my FITS images without embedding a © water mark.

 

Your reaction is clearly social. Had I not said anything, embedded the FITS headers, and included the license file in the share folder, would you even have noticed?

My least concern is CN users. The TOS requires a certain ethic—and in the one case in 7 years where I saw someone claim others' data as his own, the user got booted.

 

The oblivious bumblers and nefarious ne'er-do-wells I'm targeting are the Google freeloaders that treat CN as a source of free candy. Of course that assumes their enterprises play by international copyright rules…
