Comment : The galaxy NGC 5907 is like a needle, with a better photo it could be seen a tidal stream around the galaxy from earlier collision with other galaxies. The photo is a 1:1 pixel crop. To get a better quality a longer focal length or smaller pixel had been good. A RC (Ritchey Cretien) 10" f/8 telescope had been perfect for me.
