15 frame mosaic of the Rho Oph area. Never had the right camera gear to do justice to this widefield, and was constantly frustrated when shooting my FSQ field of view at small parts of it. Decided to shoot a 3x3 mosaic, which turned into a 3x4, which then required another 3 frames to tame nasty diffraction spikes from Antares.
All up 3 winters-worth of imaging from dark Leyburn skies (2017-2019). Thank goodness for PixInsight's mosaic tools and John Murphy's Photometric mosaic script. Most individual frames are around 7x5mins of L, R, G and B data, so its not super deep, but happy with the final resolution. Some of the final frames had as many as 22 frames/filter when had bit more time and clear skies. Won't be doing a 15 frame mosaic again anytime soon though
