Tonight I’ve been diving back into the Pleiades (M45), one of those targets that never really loses its charm. Most people recognise the bright blue reflection nebulosity at the centre of the cluster, but the real magic lies in the vast cloud of faint dust that surrounds it. This is where the challenge — and the reward — truly kicks in.
I’m currently sitting at just under five hours of exposure time across luminance, RGB and a touch of Ha. That’s already enough to start revealing the delicate, smoke-like structures stretching far beyond the bright stars. Every extra frame deepens the view, smoothing the gradients and teasing out subtler and subtler texture.
Of course, no astro session is complete without something going slightly off-script. Somewhere in the luminance stack a rogue frame slipped through with a plane streaking straight across it. So this early working version has a little surprise trail running through the field — thankfully it won’t survive into the final image once I finish the full stack. Just another reminder that astrophotography is half art, half chaos!
Processing this one has been all about balance. Reflection nebulae like M45 are soft, gentle structures, and it’s very easy to overprocess the dust and make it look crunchy or artificial. So I’ve taken a careful approach: a bit of background cleanup, controlled noise reduction, star removal and reintegration, and some very restrained contrast shaping. Little steps, but each one helps the dust breathe without overpowering the natural look of the scene.
There’s still more data to gather — especially luminance — and I’m planning to deepen the capture when the next clear night arrives. Once I push the integration further, the final image should show even richer dust detail with smoother transitions and cleaner colours.
For now, this is just a behind-the-scenes look at how M45 is taking shape. Even at this stage I’m really happy with how the dust is emerging, and I’m excited to keep building on it.
More updates soon… and hopefully fewer planes next time! ✨🔭
