This is one of my favorite. It is a barred spiral with a very weak arm nearly filling our
complete field of the ST10. Seeing was very good (at least for our average here in
Germany...). The image was streched hard to show the outside arm so it appears a little
noisy, even with a 0.8m light bucket.
A lot of back-ground galaxies are shining through the arms of NGC 4725, just an extra
bonus for this fantastic galaxy. |
