Description

This wide field image of the NGC 7000 (North America Nebula) and the surrounding region was captured on the nights of October 2-3, 2020 using a short telephoto lens, a dual narrowband filter, and a OSC DSLR. This is image includes the H-alpha data from the red channel.

Imaged with 85mm/F1.4 Rokinon at F/2, STC Duo Narrowband Clip Filter, and full spectrum modified Nikon D5300.

Total integration time was ~6 hours using 87 subs at ISO400 x 240 sec. Pre-processed using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, bias, and flats. Extracted red/green/blue channels using BatchChannelExtraction script. R, G, & B channels registered and stacked independently using StarAlighment and Integration. R channel data gives the Ha image. Averaged G & B channels using Pixelmath to generate OIII image.

R and Average of G+B channels individually post-processed in Pixinsight: Cropped, gradient removal with ABE. Noise reduction using EZ Processing Suite for PixInsight EZ Denoise. Stretched using masked stretch, TGVDenoise for further noise reduction, HDR transform, Local histogram transform, morphological transform to shrink stars.
