NGC891 close-up
Here an edge-on galaxy in the constellation of Andromeda. North is to the right.
Imaged through an 8 inch f/8 GSO RC on an EQ8. Camera was a modified Canon EOS 700D with cooling, which kept the sensor at -15 degree Celsius. No filters were used. 37 x 5 minute exposures were stacked with DeepSkyStacker in auto adaptive averaging mode (dark, flats and bias correction applied) and with the 2x drizzle function enabled and cropped. B-V colour calibrated with Regim and further processed in PS (background adjustment, lightened with curves and increase in vibrance). A very slight noise reduction and sharpened with Noiseware Community.
The next post shows the field of view with my full APS-C chip of my camera.
