Place the 4th magnitude μ Hya at the N of the field and NGC 3242 should appear about halfway to the edge on the opposite side. If you have trouble identifying it, flash a UHC or O-III filter across an eyepiece, when it will not "blink out" with the surrounding stars.

What You Should See:

The Ghost of Jupiter appears stellar in smaller binoculars, but is distinctly non-stellar with my 37×100, although I have not been able to detect the oblateness that gives it its common name in these. It is about half the apparent size of Jupiter.
