I was reading these verses and I wondered if the red dragon could possibly be Ison with its tail casting stars ( meteorites and debris ) down to the earth. After this happens the rapture takes place ? Just a thought, what do you think?

 Revelation 12 vs 3-5

3 And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.

4 And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.

5 And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne.
