Description

Another image from my Veil Nebula series. Before I figured out I could get both the Western and Eastern Veil in one frame, I took a few hours of images on both separately. This image adds an additional 2 hours data for the east side to the 5 hours data covering both sides of the Veil for a total of 7 hours worth of subs covering the Eastern Veil Nebula. I feel like the additional 2 hrs data really improved the image. I guess this shows me I need to commit to some longer integration times which is tough for me since (a) I typically only get 2 hours per night on a target through my small observing windows and (b) there are so many cool targets to image I keep jumping to something new.

Imaged on the nights of September 15/17/18/19, 2019 with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, Optolong L-Enhance dual narrowband filter, and full spectrum modified Nikon D5300.

Pre-processed using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, bias, and flats. Stacked 70 subs (360 sec at ISO 400) for a total integration time of ~7 hours. Post-processed in Pixinsight using RGB workflow: Cropped, gradient removal with ABE, MLT for noise reduction, Background Neutralization, Color Calibration, SCNR, stretched using Arcsinh then Histogram Transformation Tool, Curves Transformation, HDR transform, Local histogram transform, and Color Saturation boost.
