NGC 1977, M43, and M42
HDR composite of NGC 1977 (Running Man Nebula), M43, and M42 (Orion Nebula). Click on image for a magnified view.
Instrument: 130mm f/6 Astro-Physics StarFire EDFS refractor operated at f/6.8 with field flattener
Exposure: 7 x 8 seconds, 7 x 30 seconds, 7 x 120 seconds, and 4 x 482 seconds @ ISO 800 and 44°F
Camera: Canon EOS 20Da DSLR
Location: B. Everett Jordan Lake, North Carolina, USA
Only 50.6 minutes of integration, so results are pretty noisy even for these bright objects.
Lightroom used to apply white balance, a simple gamma 2.2 stretch, and color noise reduction to the raw files before outputting them as double-sized (4672x7008 pixels) tiff files. All tiff images aligned in ImagesPlus 6.5, subsets combined with Min Max Excluded Average, results combined with Adaptive HDR Add, then stretched with DDP Stretch. Photoshop used to assign color space, crop, mitigate horizontal banding, and set black point. Lightroom used for final adjustments.
