Sh2-88 in constalation Vulpecula
The data for this image was gathered during four nights, 23-24/08; 25-26/08; 16-17/09 and 14-15/10/2017. Imaged through an 8" GSO RC at f/8 with PrimaLuceLab 700Da camera cooled at -5 degree Celsius and -10 degree Celsius, respectively. With 8.5 hours this is my longest exposure series on an object. The image consists of 28x3 min. + 26x5 min. exposures without CLS filter and 58x5 min. exposures with CLS filter. The sets with and without CLS filter were stacked separately using different white balance settings in DeepSkyStacker. The stacking mode was set to auto adaptive weighted averaging. The two stacking results were then combined and further enhanced in PS. Background calibration was carried out with Fitswork. In the end a slight noise filter with Noiseware Community.
