      The Phantom Nebula, M74, in LRGB

      The Phantom Nebula, M74, in LRGB

      This is data from the Officina Stellare ProRC 700 telescope in Oria, Spain. It's 5 hrs 30 min of exposure with 4 filters, L, T, G, and B. I became interested in this galaxy because it's the archetype for understanding spiral galaxies, this one having 2 arms and being face on to us. I've imaged this galaxy with my own gear but found it too small in the FOV I have so the detail wasn't particularly good. So I wanted to see what I could do with a significantly better dataset.

      Dataset from which the image was processed

      M74
