Hi Scott,
Great that you found a way around light pollution and screwing open (up?) camera's. The results are surprisingly good!
I never had heard of that planetary either, but I'll have a look at it at Astrofest.
I experimented with the unmodiefied D70 and a Japanese LPR filter a year ago, and found out that the colour balance of the RAW was surprisingly neutral, compared to the green stuff that you get with an unfiltered unmodified shot. But since that filter had only 50% transmission at H-alpha I had to increase the exposure time fourfold, and back then the Baader UHC filter wasn't available. So I decided to screw up.. uh open my camera.
Sofar I haven't had the urge to make deepsky images with the modified D70 from my light polluted home site, but when that day comes I'll certainly consider that UHC filter.
Cheers,
