This is one of my results last weekend.

71FL F3.9 + 5D Mark II + LPS-V4 filter, no cropped

Unfortunately tiny stars disappear. The brightness might be too dark? I don’t know why it got dark during the processing. Anyway, this is the result as my current image processing skill. I’ve heard no-hood increases illumination around 5%. I will try to do without hood next time or I might take the flat. The flat was not taken and applied in this image.

  1. I don’t see how a hood could affect illumination. It only blocks off axis light or at least that’s all it should block
