355mm F/4.5 Newtonian, 2x and 3x barlows, ASI 174MM with red filter. Seeing 9/10.
Crater Posidonius in near perfect seeing conditions. This fantastic looking area has a panoply of rilles, starting with the very sinous one on the floor of Posidonius. The actual shape of the rille is only detectable in very good conditions and with larger aperture telescopes. The full resolution image is at the moment one of the best, in terms of resolution, acquired by amateurs using amateur equipment. Craters of around 450-500 meters are detectable in the full res image: https://maximusphotography.files.wordpress.com/2016/11/posidonius.jpg
