Welcome to the Zoo ! Great spiral

Thank You!

SDSS 588017978352599061

I thought that one looked familiar! Just to give a different view - here are some data from the Russian 6m telescope. First the false-color picture shows the northern galaxy (also known as Karachentsev 293N) through the acquisition view of a multifiber spectrograph, and the lower picture shows a raw image of spectra through 96 fibers in an array matching the rectangles above. (Alright, the SDSS image is prettier, but spectra are nice too). I worked out from this once which way the galaxy is spinning; I hope that information wasn't only on a disk that's gone away since...

NGC 3433 Hubble and SDSS images below, prev. posted here

SDSS 587732772657758339, Note: the two small edge-on spirals at 8:30 and 5:00 are unrelated distant galaxies.
Distance=129Mly (redshift independent), z=.009, NED classification SA(s)c, Apparent magnitude=12.3
Visible in constellation Leo, Cancer-Leo Cloud^{Starry Night}
In 1970, Lynds stated, feathers are "thin dust lanes with large pitch angles cutting across the luminous arms."
A 2006 reference, A Hubble Space Telescope Archival Survey of Feathers in Spiral Galaxies finds that
"feathers are coincident with interarm filaments," and
"at the primary dust lane coincident with gas surface density peaks."
