This image is the result of a 2 year scientific project between professional and amateur astronomers (PRO-AM). While a lot of time and effort is spent by amateur astronomers to obtain visually appealing images of astronomical objects, only few data is taken in such a way that can be used for real science. In this work we present the current limits of amateur technology for doing low surface brightness science when a proper observation strategy and data reduction is carried out. We have observed the M101 galaxy (in luminance) for a total time of 101 hours using an amateur telescope of 8.5 cm aperture. After a professional data reduction, we reach a surface brightness level around 28 mag\/arcsec2<\/sup>\u00a0over a field of view of 1.2 deg2<\/sup>. This result shows that current amateur astronomy still can compete in depth with professional telescopes when large areas are explored.<\/p>\n

This project was presented during the 355 IAU Symposium \u201cThe Realm of the Low-Surface-Brightness Universe\u201d that took place in Tenerife (Canary Islands, Spain) in 2019. Everything started at the podcast Coffee Break Se\u00f1al y Ruido.<\/p>\n

[icon name=\"thumbs-up\" prefix=\"fas\"] Support my work. If you want to help me continue with my work, please feel free to buy, just for a few pennies, one or several of my images. The price does not reflect the amount of effort involved in each one of the images. Some of them implied weeks, months and even years of hard work. With your purchase I will be able to continue capturing photons of our amazing universe.<\/p>\n
