Description

M45, the Pleiades, or as I knew them when younger, the Seven Sisters. I love M45, and I like a bright and blousy rendition, but I just pulled this back from completely blinding with a little HDR processing, which has brought out some of the detail in the reflection nebulosity. 

Processing was fairly minimal, and I've just let the stars be as big as they want to be. I was aiming to present a wider field, with more of the dust in the area, but had big reflection artifacts in all four corners, forcing more of a crop then planned. And I still had to do a bit of fiddling about to remove a bit from the remaining frame. Despite lots of matt black paint and flocking tape, I still haven't worked out where the reflections are coming from!

I also lost 46 subs to the cloud, so I'm quite pleased with the result from 37 minutes of data.
