This object was found once again by blindly slewing the scope around with the 30mm ep. Adding the UHC-E into the mix definitely made it stand out more. however I could still not make out enough detail to even have an educated guess at what it was...
Interesting reading Alex

NGC 6629 is indeed a planetary nebula, with a magnitude of around 11, depending on the source. It is listed as such in many catalogues (SIMBAD gives 21 identifiers). The fact that the UHC-E filter made it stand out more is a pretty reliable indication that what you were looking at was a PN as opposed to a galaxy, since galaxies are usually continuum emitters (they emit many wavelengths across the spectrum) and do not benefit much from UHC type filters.
