Bad weather drives me crazy. In December last year I collected RGB frames for M45 Pleiades open cluster. I already had luminance only, but conditions during RGB collecting was very poor. However due to lack of new material I decided to put it all together, so here it is. I will get back to Pleiades cluster at least one more time, but not in my light polluted backyard. 

Pleiades are dominated by hot, B-type stars, that age is estimated to about 100 million years. The reflection nebulae that covers Pleiades stars is not related with this open cluster. It is just a interstellar molecular cloud, that M45 is passing through.
