Well, I went out to the Mojave desert for a couple of nights last weekend to gather luminance data on this object, but seeing was very poor and I had a constant 8-12MPH westerly wind that made focus and guiding a nightmare. I was only able to salvage 9 out of 49 subs over the two nights... with the good subs falling into the 1.8-2.5 FWHM range, and the rest waaay above that.

Just enough to show the potential of this object... I'll try for it again later.
