    Description

    Data for this four narrowband channels composite image was accumulated during 40 to 50 nights (I honestly lost the count) over several months in 2018 and 2019:

    HA: 194 x 900s + 157 x 1200s
    OIII: 124 x 900s
    NII: 88 x 900s
    SII: 22 x 1200s + 167 x 900s

    All filters were 3nm.

    The image is a blend of 0.55 HA_SNO + 0.1 HA_HNO + 0.35 HA_HSO.

    For anyone interested in going deep on Helix, I recommend using a 5nm Ha and a 3nm OIII filters only.
