Visible crew/equipment: When Adam, Barbara and Juno ascend a staircase, talking about how Adam and Barbara should start more simply if they want to scare the Deitz family out of their home, there are two tape markers - a yellow and a blue one, very clearly on one of the steps. (00:34:35)
Visible crew/equipment: When Barbara tries to leave the house and falls into the sandworm's world you can clearly see her knee pads. (00:19:00)
Visible crew/equipment: When Otho is doing the Seance, Adam and Barbara appear in their wedding clothes and then float above the table. When Lydia releases Beetlejuice, everyone gets up and leaves the table, and in this wideshot the black wires that Adam and Barbara are suspended from are visible. (01:15:25)
Visible crew/equipment: Barbara shows Adam their lack of reflections, then points out the book entitled "Handbook for the Recently Deceased" and its publisher. At the very start of the next shot in their bedroom, we can see the reflection of the moving boom pole/mic on the window above the bed. (00:10:10)
Visible crew/equipment: When the small priest emerges from the fireplace and then when he goes on to do the wedding ceremony for Beetlejuice and Lydia, you can see a thick black tube running out of the priest's right leg, trailed behind him. (01:18:30)
Visible crew/equipment: There is a unknown 3rd person helping Charles and Otho remove the model from the attic. You can see him briefly just as the scene ends on the left side of the screen moving the front portion of the model, closest to the camera, between us and Charles. Charles and Otho would be hard put to move that entire model by themselves. Otho says it is sectional, but they still seem to move the entire model in one piece.
Answer: No; it was left strictly to the imagination of the audience.
