Two different locations, more than 200 km apart. Two different telescopes, different size, focal length, light. Two different tools for collecting photons with completely different parameters.
Until now, my computer didn’t really have much to count, but everything changed when I get idea to try, to stack two totally different data sets together. I like such challenges. I’ve spent a lot of time on it with processing stack. The average of time consumed with one single stack processing, took me around 6 hours. It was test stacks + experiments…. I’ve lost in time how many there were, hours or maybe days spent only for the processing of the data itself. Anyway, the power meter count what it wanted and I will pay for this later.
An interesting fact for me was, that the result stack reached a resolution of 23k x 23k [px], and its size was of 6.3 GB. Displaying such an image greedy consumed ¾ from the available memory of my computer. Processing such a photo was a bit tiring, after cropping it was better, but the final .png file with photo, was just over 300MB in the resolution of 9085 x 6950 [px].
Well…. I must admit that I had a lot of fun with it and a lot of side text was written during processing of stack. Something will come of it.
About the galaxy itself
The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye.
