It is imperfect. The stars are not exactly good (there seem to be some pinched optics, a bit of miscollimation), there is light pollution etc. But, I think the data are salvageable!</p> <p>You can download a zip file with the LRGB stack here: <a href="https://github.com/deepskydetail/data-downloads/releases/download/M45_Bortle_6/final_M45_Test_LRGB.zip" target="_blank" rel="noopener noreferrer">M45 Data</a> </p> <p>Here is a tutorial I did on Andromeda:</p> <div style="position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden;"> <iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share; fullscreen" loading="eager" referrerpolicy="strict-origin-when-cross-origin" src="https://www.youtube.com/embed/0Ft8_TO-Gw4?autoplay=0&amp;controls=1&amp;end=0&amp;loop=0&amp;mute=0&amp;start=0" style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; border:0;" title="YouTube video"></iframe> </div> https://deepskydetail.com/about/ Mon, 01 Jan 0001 00:00:00 +0000 https://deepskydetail.com/about/ <p>Hi! I&rsquo;m Mark. I like astrophotography. I&rsquo;ve been doing it for over ten years, trying to stay on a budget. This forced me to think about how to make the most out of the data I collect. I decided to make a <a href="https://youtube.com/@deepskydetail" target="_blank" rel="noopener noreferrer">YouTube</a> channel to share what I learned. I have an extensive background in statistics and modeling, having been trained as a cognitive scientist whose job is to find the signal among the noise. And believe me, data taken from humans can be extremely noisy!</p>
