NGC 4151
Found in the constellation of Canes Venatici a mere 62 million light years away NGC 4151 has recieved the nickname 'Eye of Sauron'. This unusual spiral galaxy has an active black hole at it's core. This AGN (Active Galactic Nucleus) is one of the closest to us.
How many background galaxies can you count?
Data was gathered from my Bortle 7 back garden over 3 nights during the 1st week of April 2025. I had to delete half my subs due to guiding and star trailing issues.
Boring Techie bit:
Telescope: Skywatcher Quattro 8"
Mount: EQ6r pro
Camera: ZWO 533mc pro
Filter: Optolong UV/IR.
Guided and controlled by the ZWO asiair+ using Altair 60mm guide scope & ZWO 585mc.
60 light frames 180 seconds each.
Stacked with darks, flats, dark flats & bias using WBPP in PixInsight.
Processed using Graxpert, StarNet2, PixInsight & Affinity Photo.
