This may be the last time I capture deep sky objects with my Celestron NexStar 8SE SCT. It served me well, but now I am in the hunt for a refractor with close to the same focal length. These are my astrophotography setup details for Sh2-112: Target: Sh2-112 Imaging Telescope: Celestron NexStar 8SE (1280 focal length) Focal Reducer: f/.63 Mount: Celestron CGX Polar Alignment: QHYCCD PoleMaster Imaging Camera: ZWO ASI1600MM-Cool Filters: Ha=60x180s OIII=50x120s Total Exposure Time: 4.7 hours Gain: 139, Offset: 21 Guide scope: Orion ST80 Guide Camera: Lodestar X2 Guide Software: PHD2 Calibration Frames: Darks: 50, Bias: 50, Flats: 50 Capture software: Sequence Generator Pro (SGP) Stacking software: PixInsight Post Processing: PixInsight Dew Shield, Dew Heater Strip Astrobin: http://astrob.in/311964/0/ #celestron #8SE #nexstar
