AstroDMx Capture was used to capture 2h 10min of 5min exposures of M27 with an SV605CC OSC camera and an Altair Starwave ASCENT 60ED doublet refractor with an 0.8 Reducer/flattener and a Pegasus FocusCube v2. An Altair 2” magnetic filter holder version 2 was placed in the optical train and contained an Altair quadband filter. The equipment was mounted on a Celestron AVX GOTO 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 on the Linux imaging computer. PHD 2 was used for autoguiding and was running on a separate Linux computer.

The image data were calibrated, stacked and partly processed in PixInsight and further processed in GraXpert, and Gimp.
