| 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. |
