    M27 'Dumbbell Nebula' with Canon Rebel T7i 'modified' using a Baader Ha 7nm and Baader Hydrogen Beta 2in. filters
    for 691secISO6400 each with a TeleVue .8XReducer/Flattener for 951mmF/L with a 152mm A+M Refractor(OfficinaStellare 1200mmFL) and
    'guiding' with MaximDL Pro V6.16 with Astro-Physics 1200GTO Mount . One image with each filter last nite and then clouds came in so I
    didn't get to a Baader SII filter I have but all these filters are 'parfocal' . The two TIFF images were combined in "ImagesPlus" and the
    FeatureMask was used . The JPG is Scaled to 2.0 and cropped , the FITS is done thru MaximDL Pro and the 'Half Size' applied two times and
    it is cropped also and "PinPoint Astrometry" 'solved' for 951mmF/L .
    Someone else's .Au PDF which might be Australian is here that talks about the filters .x
