An Altair Starwave Ascent 60 ED doublet refractor with Field flattener-reducer and a Pegasus FocusCube V2, and fitted with an Altair 2” Magnetic filter holder with an L-eNhance filter and a prototype SC715C OSC camera, was mounted on a Celestron AVX mount. An SVBONY SV165 guide-scope fitted with a QHY-5II-M guide camera was mounted on the imaging scope.
The mount and focuser were controlled by AstroDMx Capture via an INDI server running on the imaging computer indoors. PHD2 multi-star pulse auto-guiding was done via the INDI server on a separate Linux computer indoors.
The data were debayered, calibrated, stacked in ASIDeepStack and further processed in GraXpert, Cosmic Clarity, Gimp, ACDsee and G'MIC. Three renderings are presented here:
