AstroDMx Capture was used to capture 110min of 5min RAW exposures of NGC 6755 and 6756 and associated dark nebulae in Aquila with an SV605CC OSC camera, 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 data were calibrated, stacked and part processed in PixInsight and further processed in GraXpert, Seti Astro Suite Pro and GIMP.
