Hood - South Collimator, Melbourne Observatory, circa 1880s Object Reg. No: HT 27291

Hood for the South Collimator Field Lens at Melbourne Observatory, circa 1880s. The South Collimator was erected some distance south on the meridian line of the 8 inch transit telescope, to assist in testing the soundness of the telescope's piers and pivots, or any other factor that might disturb the accuracy of measurements with the telescope.
Black painted metal box with rusted exterior, hinged cover and pentagon-shaped side profile. There are six small lugs with holes attached to the interior walls, possibly for latching the hood over the lens.
