This should really be in the Skyrim section of the forum but the Oculory is suppost to used at daytime and you have to use longish bursts of magic (there are plenty of youtube videos to help show what to do). If it is bugged on a console the only fix is to quit and reload or go back to a older save and try again (leaving and coming back too but that can cause other bugs), if your playing on PC you can use the console command -

player.SetStage MG06 55

That should skip the quest forward a bit.
