type /names #channel_name
if lucky, list of names will reveal itself
showing who is op and who isnt.
if you find op's on list (nicknames with @) just
/msg them or /query them
if that does not help then type this:
/window @debug
then type: /who #channel_name
in new window called Debug you will find
results simmiliar to this:
server_name WHO #channel
server_name 352 you #channel irc_name host server nickname H*@d : bla bla bla
if @ sign is in that/those lines (depends how many lines you have as result),
then nickname is OP
so this is alternate way of finding ops in channel
