1. A method of recording images within a furnace using a thermal imaging camera comprising a borescope connected to a digital camera unit, the furnace having an interior, the method comprising: (a) inserting the borescope into the interior of the furnace, (b) collecting one of more images of the interior of the furnace using the thermal imaging camera with the borescope at a first position, and (c) moving the borescope from the first position to a second position and collecting one or more images of the interior of the furnace as the borescope is moved from the first position to the second position, wherein borescope movement is guided by means of a guide device comprising a movable borescope mounting, mounted externally on the furnace, wherein the movable borescope mounting provides a circular movement from the first position to the second position, thereby causing the borescope to describe a cone within the furnace as the borescope is moved from the first position to the second position.
