tomato Posted December 18, 2022 Share Posted December 18, 2022 This is another of my "how deep can you go" efforts, Abell 370 in Cetus. This is 305 mins made up of roughly half LRGB with the Esprit150/ASI178 and half with the Esprit150/IMX571 OSC. Calibrated and stacked in APP, processed in PI and AP. I have only used NoiseXterminator on this one, StarXterminator included the galaxy cluster with the stars, so BlurXterminator made them into neat and tiny red stars. This is the most distant of the Abell clusters, some 4.1 billion light years away. I was hoping for perhaps a tiny hint of the gravitational lensing arcs as seen on the HST images, but I was being too optimistic. This object only achieves an altitude of 35 degrees from my location, right above my neighbour's roof. Thanks for looking. Crop 17 Link to comment Share on other sites More sharing options...
