  We present an analysis of the results of photometric investigations of two
distant comets, C/2002 VQ94 (LINEAR) and 29P/Schwassmann-Wachmann 1, obtained
with the 6m telescope of the Special Astrophysical Observatory of the Russian
Academy of Sciences. The comets under study demonstrate sufficient activity out
of the zone of water ice sublimation (at heliocentric distances longer than 5
AU). In the spectra of the investigated comets, we found the CO+ and N2+
emission. The presence of this emission may say that the comets were formed in
the outer parts of the Solar System, in a protoplanetary cloud at a temperature
<=25 K. We found that the photometric maximum of the ionosphere (in the CO+
filter) of the comet C/2002 VQ94 (LINEAR) is shifted relative to the
photometric center of the dust coma by 1.4 arcsec (7.44*10^3 km) in the
direction deflected by 63 deg from the direction to the Sun. Using special
filters to process the images, we picked out active structures (jets) in the
dust coma of the 29P/Schwassmann-Wachmann 1 comet.
