One of the brightest nebulae that can be seen with the naked eye is the one of the brightest nebulae that can be seen with the naked eye. Astronomical photographer Matt Harbison, who has continued to photograph the Orion Nebula for more than five years, combined his photos into one, completing a super-resolution photo of 2.5 billion pixels.
When you open the page, a large picture of the Orion Nebula is displayed. When you click the screen, it expands with each click. He spent more than 5 years taking 2,508 photos using the QHY 16200 CCD, a camera dedicated to astrophotography with a 16.2 megapixel KAF-16200 image sensor for $4,800.
It is said that it took more than 500 hours to be edited using several programs (SequenceGenerator Pro, PHD2 Guiding, Pixinsight, Astro Pixel Processor, Adobe Photoshop) to combine all the photos into one. When the first image processing was done earlier this year, it could not be processed due to the PC specification problem, and in the end, in August, I purchased a new PC with 256GB of memory in a Ryzen Threadripper with 24 cores and processed the image. It took 42 hours, including 23 hours for photo positioning and 19 hours for combining, and eventually produced one super high-quality image. Related information can be found here .
