Although a deceptively small 6' X 4' in size, I have always loved this galaxy in Eridanus, NGC 1300, it reminds me of a lawn sprinkler spinning slowly
When Hubble released it's version in around 2004 I was gob smacked by the number of very distant background galaxies that could be seen
through the disc of NGC 1300

.. it was an incredible site!
Well now almost 10 years later and armed with my little AG12 I can actually pick many of them up, which to me is really quite remarkable. I have no idea of their magnitudes but if there aren't some in there fainter than magnitude 23 or so, I'd be very surprised

Unbelievably MEGA distant galaxies!

Sigh...Oh to be imaging from Cerro Tololo
