NGC 4565 is one of the most beautiful galaxies seen edge-on. Visually with a telescope the dust lane can be seen stretching from end to end. Amd ti is comparatively bright.
The slight warp of the disk is caused by several nearby galaxies.
There were setbacks during the change to N.I.N.A. After some initial successes it didn't work very well; observing was demanding: sometimes the telescopes were not aligned correctly, and then I made wrong decisions in N.I.N.A.
Probably have to put it under learning.
As so often I imaged this object some time ago already:
