Description

Imaged the NGC7000, the North America Nebula, towards the end of this past summer from my backyard in the northern suburbs of Washington, DC. This turned out to be a great target for me thanks to high declination (away from the worst of the light pollution to my south) and great H-alpha signal which really shines with the modified DSLR. Imaged in both OSC RGB and NB H-alpha.

Imaged with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, Optolong 12nm Ha Filter, and full spectrum modified Nikon D5300.

Processiing in PixInshight. Calibrated using batch pre-processing (BPP) script using darks, bias, and flats. Extracted red channel. Registered and stacked using StarAlighment and Integration. Total integration time of ~1.5 hours using 29 subs at ISO400 x 180 sec. Post-processed in Pixinsight: Cropped, gradient removal with ABE, MLT noise reduction, stretched using Histogram Transformation Tool, Curves Transformation, TGVDenoise, HDR Multiscale Transform, Local Histogram Equalization, and Morphological Transformation to shrink stars.
