Dim and difficult. This pair was invisible last night in milky conditions with naked eye limiting magnitude of only 4th mag. All I am seeing in today’s improved conditions are the central regions of these two galaxies. The view is much better through the Ethos than with the Clavé. NGC 2525 is the larger, oval object.
