WebAnswer: Always put the more reflective side towards the telescope side. To guide you we already put a small arrow on the filter rim, on those filters were the position matters. This arrow indicates which face of the filter should be directed towards the sky (telescope-sided). All cell-mounted filters are already oriented in a way that the most ... WebEach filter images a section of sky nearly, but not exactly, simultaneously (each filter is separated by 71.72 seconds). The filters always observe in the same time sequence: r, i, u, z and then g. A mnemonic for remembering the order is “robert is under ze gunn.” The multiple bands allow a determination of the colors of detected objects.
