Ive discovered a little trick that seems to work very well. My scope has an optic piece (I don't know what its called) that attaches to the focusing aperture. It is angled at about 45 degrees and has a mirror that is supposed to correct image reversal at the EP. If I place the barlow first, this device next and the EP last, my images become much clearer. Using the 20mm in this way provides me with a view much like using the 6mm alone. I was able to site Jupiter and pick out four of its moons. Using the 6mm with the barlow in this way also allowed for a better image than before, however there was a fair amount of degredation. I have also noticed that there is an abberation of some sort on the mirror of this "unnamed" device and since it is sealed I can not clean it. My next attempt (probably this evening) will be to view objects without this device and see what I can get. Thanks for your advice, I am hoping to get an opportunity to view some Messier objects as soon as I can get to a spot that has less pollution. Ive been viewing in my backyard in a small city during a full moon! Thanks again
