Andromeda Nebula taken by NSP of Xingming Observatory, in combination with Mr. Maosheng Chen's originals (detailed below).
Exposure Total 46x180s at ISO 800; from which, 24 are acquired by Maosheng Chen. Thanks for Maosheng's generous offer of the raw files.
Processing IRIS: Stacking; two baches separately stacked, and added by an optimized ratio as discussed in Stacking_of_Two_Images (
MaximDL: MaximDL generates two layers: the nebulocity and star layers. Nebulocity layer: Erode (3x3) --> DDP --> Gaussion (1.5) Star layer: A simple stretch
PS: Blending the nebulocity and star layers by Ligher; and a high pass layer blended by Overlay. Finally, some final touch (Color balance, brightness and contrast).

Two PS operations greatly improved the quality
1. High-pass layer blended by overlay (or alternatively, by Soft Light or other lightening blending modes)
2. Gaussion blur on the nebulocity layer.
