<p>This is the Great Orion Nebula, M42. I realized this is fairly easy to see with a sufficient optical boost from my backyard which is roughly Bortle 6/7. This is my second night trying to image this object (or any DSO, actually).</p>
<p>This is a stack of 10x88-second exposures (roughly 15 minutes total exposure time). Polar-alignment on my SkyGuider Pro proved to be a bit difficult (once I added the camera and counter balance I had to re-align), so this 15 minutes is the result of me fiddling for an hour and a half or so. I did all the processing for this photo using libre software. Camera/lens correction in RawTherapee, aligned using <code>align_image_stack</code> in Hugin, average stacking using G’MIC, final stacked image tone curve/RGB curve/saturation adjustments in RawTherapee.</p>
