Using my home made IIE (Image Intensifying Eyepiece) which is virtually the same as a Collins unit I have seeen the seen the central star in M57 once while using a 15-in f/5 dob. This was on a good night on top of a dark mountain near 5000 ft.
Last night here was partly cloudy and very hazy. Using a 91mm f/6.6 apo and the IIE I viewed (among other things) three globulars: M4, M13 and M92. All were just blobs rather than globs. No stars resolved with magnifications up to 150X. But with the IIE working at 25X about a dozen stars were resolved in M4, two dozen or more in M92 and and 40+ in M13. I would expect the BIPH to perform even better.

Two dozen eyepieces, a dozen binoculars, a half dozen refractors, two reflectors and a homemade Image Intensifier Eyepiece (IIE). All products subject to change by the owner at any time.
