My best versions of the Ring Nebula so far.

A couple of weeks ago I took some images of the ring nebula. They were posted at
https://www.uglyhedgehog.com/t-743442-1.html and
https://www.uglyhedgehog.com/t-743879-1.htmlThese new images used the same data but were reprocessed using some masks I created to greatly reduce haloing around the stars along with some additional processing to improve details in the ring and augment some of the small dim distance galaxies in the image. The most easily visible galaxy in the image is IC 1296 to the upper left of the ring. This is a barred spiral galaxy with a magnitude of 14.8 and has an estimated distance of 240 million light years. This is the only galaxy in the image that showed up in my charts. Most of the other galaxies in the image are much dimer and smaller but can be seen using double download. (Note: the ring nebula is only 2300 light years away.) I consider these the best images of the ring nebula I have been able to create so far.
The first photo used Luminance, Red, Green and Blue filters with a mono camera to gather the data for the image.
The second image added in just over 11 hours of Hydrogen Alpha filter data to capture the dim outer halo around the ring. The Ha data was masked to only include the halo around the ring nebula (Without masking everything turned red). Additional information about the exposures and equipment used can be found in the links above.
All questions, comments and suggestions are welcome.
M57 the ring nebula taken using LRGB filters. The blue color is manly florescence of oxygen gas excited by the hot white dwarf star in the center of the nebula. The outer thin red ring comes from the florescence of nitrogen gas.

M57 with Ha data added to the red channel. This brings out the dim hydrogen gas expelled long ago by the star in the center of the nebula

Who needs the James Webb ...., we have Ballard. Incredible shots and thanks for the descriptions.

Hi Longshadow
Thanks for viewing the images of M57 and for the Thumbs up.

Hi SonyA580
Thanks for checking out the images of the Ring Nebula and for the comment. The resolution is not up to Hubble or James Webb quality but came out decently. A couple of decades ago this type of image wasn't possible for amateurs.

Hi flyguy
Thanks for the Thumbs up and for viewing the images of M57.

I don't know - maybe you are a little too close to the subject..... (That's a joke! This is awesome! What would Galileo think?!)
Yu did very well with the equipment you have. We could all take Webb type shot if we had the $10 billion.

Love the last image! The universe has some wonderful stellar objects.
