Note that the full moon was coming up from behind some trees and the some of the lights in my house were still on.

I hope this is not a dumb question, but does the BiPH work in conjunction with eyepieces, instead of (i.e., it provides its own magnification), or with its own (proprietary?) magnification assistance?

B Cuddihee, handholding was not a problem with the unit and the 105mm camera lens. It's very lightweight.
Wes, Doug said 60 days, that puts it around late September or October.
David, it works very well with the Ha filter. In fact there was talk of bundling it with one.
Brad, it does not work in conjunction with eyepieces - rather think of it as it's own eyepiece.

If I want pictures, I can have these from the Hubble website in uber resolution, or on APOD.

The tool itself is interesting tho. There were definitely times I prefer the naturally aspirated views, but that added capability the image intensifier gave was absolutely amazing. The ability to cut through light pollution will be more than worth the ticket for some folks.

One thing I am curious about-- I know the BIPH will work great on nebulae and clusters, less so with galaxies. I have not heard how it works with comets. Would this be a good tool for comet hunters?

Sounds OK... but it's probably not for everyone. Personally, I don't care for the green view that these devices provide. A while back Gary and I spent a good bit of time using his I3 in my 25. I thoroughly enjoyed the opportunity to use one, and determined that it's not for me.
I too tend to prefer the "naturally aspirated" views, but there's no denying that these: 1) allow you to see more than you would otherwise, 2) present a completely different version, and 3) cut through light pollution.
These is more appealing to me than something like the Mallincam because of the ability to use it in real time. Not only is it a live view, you don't need a tracking mount.
If at all possible, I would suggest a try before you buy approach with this - although honestly - that's not probably going to be all that possible. They ARE trying to get units around to the major star parties tho, so if you do that circuit, you just may get a chance.

It's a neat idea, but it's a shame that such a thing is necessary for some observers. Until we can get light pollution laws with teeth here in the US, desperate observers will have to rely on light amplification gadgets.
There would have to be no lights anywhere to darken the skies enough to compare with the BIPH. We'd be back to the pitch-darkness of the 17th century, dark enough so that in downtown Seville Count Almaviva can mistake his wife for the serving-maid Susanna (Mozart's "Marriage of Figaro", Act IV). But if it were that dark, I'd never able to find the bloody focus knob on my scope much less anther eyepiece.
Like everything in our hobby, the BIPH can't do it all. It's better for some objects than others. It's monochromatic, which may or may not bother you. There's scintillation to a greater or lesser degree, which may or may not bother you. There are a few black spots on every tube, which may or may not bother you. It's expensive, which may or may not bother you. On the other hand, it triples your aperture and allows you to see things you've never seen before. The last time I saw the North American Nebula was with 7x50 binos from 9,000 feet in the pitch-black Colorado Rockies; Doug showed it to me from his driveway in suburban Westchester (maybe 150 feet above sea level and 35 miles north of Times Square) on a very hazy, very humid night, with a H-alpha filter in front of the cheapie 105 mm C-mount lens on the BIPH. It's hard not to be a believer. And the thought of it on a 30" scope!
I figure the conversation will probably go like this:
LARRY: I ordered a BIPH.
ELYSE: You're spending 4 grand on ANOTHER telescope thing?
LARRY: No, I'm saving $50,000 by not buying a 20" Meade.
ELYSE: Come on, that's not really saving. You're still spending $4 grand.
LARRY: But when you bought your mink coat you explained that you actually hadn't spent money, you saved thousands because of the discount.
LARRY: [Reminder to self: buy some jewelry for her, too.]

If it worked on galaxies I'd be more interested though, it doesn't sound like its the complete package, yet.
