Mel111 and Galaxies (AT90CFT RMod).jpg
This is a framing of the large naked-eye Mel111 Coma Berenices star cluster to include some of the telescopic galaxies in the area, notably the edge-on Needle Galaxy, NGC 4565, at lower left and the spiral galaxy NGC 4559 at upper left. NGC 4494 is to the right of the Needle galaxy. Many other NGC and PGC galaxies down to 15th magnitude dot the field.
This is a stack of 15 x 3-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 1600. 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.
