Orion Nebula and Horsehead nebula in Hydrogen Alpha. I used a Canon 75-300mm lens set to 100mm at about f6 attached to a cooled CCD camera via an Geoptik adaptor. This image was consists of 15 x 300 second exposures unbinned that were also unguided.

The Orion nebula has always been tricky as it’s core is so bright. This was still a problem in this widefield image, as Orion is still bright and the Horsehead is very dark. I still used DPP in Maxim DL when processing this, then just tweaked the levels, brightness, contrast and sharpened it in Photoshop.
