This is a framing of the bright Messier spiral galaxy M101, with a number of its nearby galaxies in Ursa Major. The odd galaxy below M101 ins NGC 5474. NGC 5473, 5485 and 5486 are above M101. an edge-on at top centre is NGC 5422, while at the top edge is NGC 5443. The elongated galaxy above the blue star 86 UMa at right is 13th magnitude UGC 8337. This is a stack of 15 x 6-minute exposures with the Astro-Tech 90CFT apo refractor with its 0.8x Reducer for f/4.8 and 430mm focal length, and the filter-modified Canon R camera at ISO 800. No filter was employed here. Autoguided with the MGENIII autoguider. A starless layer created by RC-Astro StarXTerminator plug-in that contained just the galaxies helped to bring out the galaxies separate from the stars in processing. Plus I applied a Detail Extractor action in Nik Collection 6 Color EFX. Shot from home May 14, 2023 as part of testing the 90CFT scope.
