In the debate of which object in the Herschel 400 is the most difficult object, this low surface brightness galaxy located just inside the southern boundry of Serpens is the other contender. I observed it also with my 6 inch dob from Pearson College. It was on July 22/08 at the same time in the evening as I had observed NGC 6540 on the previos evening.

By far, this was a more difficult object to pick out of the background sky. Getting the right balance of magnification and contrast was difficult. At 80X magnification and averted vision I was just able to make out it's very faint elongated shape. It had a very even surface brightness.

This is how I saw this galaxy with my 6 inch dob at 80X.

To myself anyway, the debate is over.
