    This image is a first for me in many ways:

    This is my first image taken with a CCD camera (Trius SX-814) before I was using a Canon 500D DSLR.

    It's the first time I have used all three Narrowband filters H-a, OIII & SII, before I just used H-a.

    It's the first time I have managed to take some 30min subs (was 10min), and also used FocusMax with Pinpoint for focus and plate solving, making returning to the same field of view much easier.

    This is also the first image I have processed completely in PixInsight (v1.8 RC7). Before I was just using the pre-processing and DBE and finishing in Lightroom/Photoshop.

    H-a 150min (12 exposures 600s and 1200s)
    OIII 140min (9 exposures 600s and 1200s)
    SII 181min (11 various exposures from 180 to 1800s)
    Total integration 7.9hrs over 5 nights from 2013/09/22 to 2013/10/15.
