This is a framing of the bright Messier spiral galaxy M106 at top, with a number of its companions and nearby galaxies in Canes Venatici. The edge-on spiral to the right of M106 is NGC 4217; the elongated spiral at upper right is NGC 4096; the edge-on spiral right of centre is NGC 4144; the more face-on spiral at bottom is NGC 4242. Many other NGC and PGC galaxies down to 15th magnitude dot the field. The location of the galaxies of interest leant themselves to a classic Rule of Thirds composition with M106 at the intersection of the upper horizontal and vertical third lines. 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 12, 2023 as part of testing the 90CFT scope.
