- Thin Galaxies -

Here I will present some quite thin galaxies with an axis ratio of at least 1:5. Nevertheless this value is calculated from the given angular size, so the visual impression can differ.

8" f/6, 150x, Bortle 6+, NELM 5.2, SQM-L 19.6
At 100x just a hint of a galaxy at the limit of perception. At 150x the galaxy appeared as faint, elongated, thin glow. North of the galaxy an apparent field star.
