- Thin Galaxies (Dra) -

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.

NGC5965 (GLX)

../dss/dss2blue_153402.46_+564108.16_5_web.jpg

The observation with the 4.5 inch Newtonian was made about three years later than with the 8 inch Dobsonian. This impressively shows the impact of experience of an observer.

4.5" f/8, 60x, Bortle 4, SQM-L 20.9
Quite thin, elongated, evenly bright. Fairly well seen with averted vision.
