October 2013: NGC7331 galaxy group

In a moonless, dark night, I imaged this beautiful galaxy, surrounded by other minor galaxies.

As usual, I applied deconvolution in postprocessing, using luminance and custom star masks to do so. I boosted the blue color of NGC7331.

Guiding was quite good, and I run a Pempro alignment process before imaging, to allow for a smooth guiding. In fact, I was able to turn off corrections along the Y axis (declination) during some time while imaging (close to the meridian).
