This photograph was taken from my back garden in Kirkby-in-Ashfield (Near Mansfield) on 4th and 5th August 2016 using an Officina Stellare Hiper Apo 115mm refractor on an NEQ6 mount. This was guided using an Altair mini-guide scope with QHY5II camera and PHD2 guiding. The image was captured using an Atik 383L+ with an Atik EW2 filter wheel and Astrodon HA, OII and SII filters. I took 16 x 5 minute exposures through each of the three filters i.e. 48 exposures with total exposure time of 4 hours. I used Bias, Darks and Flats as calibration frames. Captured using Sequence Generator and processed using PixInsight and Photoshop CC.
