Therefore, photoreceptors of nocturnal geckos, despite the rod-like shape, ultrastructure, and function [1-3], are actually cones evolutionary adapted to fulfill the role of rods and allow scotopic vision. This hypothesis was originally proposed by Walls and it is known as "transmutation theory" [4, 5].

V and B photometry was invented by astronomers for scientific work, not for amateur astronomers using scotopic vision. Perhaps the visual estimates from many years ago found in old catalogs are not so bad after all - at least the correct bandpass was used.
