bringing the thread back on track. Here are the two scopes side by side. A first edition TV oracle probably circa 1986 and a chrome draw tube tv76 which probably early 2000s and is certainly pre 2005.
The first thing id say is that the case for the Oracle is in my opinion the high point for Televue cases. This is the version #1 Oracle with the screw in dew shield. Version #2 with the sliding shield may have come in the soft case. The modern soft cases are ok. But i prefer a hard case. And these Oracle cases seem better than some of the earlier ones (eg a Reneissance I have).
So as far as i'm aware...
Version 1 Oracle = Screw on dew shield, dull / satin finish to the black parts and Hard case. chromed metal focus 'mag wheels'
Version 2 Oracle = sliding dew shield gloss finish to the black parts and soft case. Black Plastic / Silver insert 'mag wheels'
The first version of the Oracle had a satin finish. Even though its older than the tv-76 by probably circa 10 years it looks more like the current range of TV scopes. The later version of the Oracle shares the same gloss finish to the black parts like the TV-76.
The clam shell on the Oracle doesnt have provision for a finder whilst the 76 does and is pictured with the tv red dot finder. The screw on dew shield works fine but isnt as convenient as the sliding shield on the tv76. Both clam shells have the standard tv threaded holes for the tv dovetail or other dovetails.
Both Oracle and 76 have the same style chrome draw tube and single speed rack and pinion. (Retro fit feathertouch 1:10 dual speed pinion units are available that essentially just replace the mag wheel part of the focuser and retain the name plate and serial etc). The single speed on both is lovely and smooth.
Both Oracle and 76 have the great (but squeaky) screw on lense cap.
Both Oracle and 76 have great fit and finish and feel completely bomb proof.
They are both 3”/76mm the tv76 is a shorter scope with a faster F.
Both work well with the TRF2008 x0.8 reducer flattener and a dslr. In the case of the 76 the trf-2008 gives approx an f5.
Optically the Oracle is a cemented triplet made pre ED glass. (Ive never seen any discussions about what glass it was -tv seem to keep tight lipped about such things) the tv76 is an air spaced doublet made with some sort of ed glass.
Ed Ting gave a nice review of the Oracle and 76 back in the day and had good words about both, favouring the 76.
Both I think give great views.
The oracle is relatively scarce, the tv76 much more common. A quick unscientific look at the last few sales here on cloudy night seems to suggest cost wise the oracle and chrome tube 76 are both in the 800-1000
dollar range. But as always condition is everything.
