    Description

    This image shows a number of dark and light nebulae in Cassiopeia. The most prominent dark nebulae are (from left to right): LDN 1357 (just to the left and slightly above centre); LDN 1355 (above right of LDN 1357); and LDN 1358 (the largest). The reflection nebulae are: VdB 9 (just to the left of SU Cass – the bright central star); and VdB 7 (the ultra faint nebula around RZ Cass – the bright blue star in the right lower part of the image).

    These nebulae were photographed between 23 November and 29 December 2019 from a rig in Spain that is privately owned and remotely operated by Barry Wilson and me.

    Capture details are as follows:

    Telescope: Takahashi FSQ 106
    Camera: QSI 683
    Filters: Astrodon
    Mount: 10 Micron GM1000HPS
