Shelbydiamondstar Photography with the Star Adventurer! WOW

Orion "deepscape" over Bond Falls.

This telephoto view really brings Orion closer!! ❤

The jewel of the winter sky! I did have to pano this shot to get the entire field of view. These shots are so tricky, but I just love the telephoto compression effect so much! I have grown to really enjoy the winter skies, despite the extra effort in hiking to locations through snow and the bitter cold.

EXIF -
Nikon Z6 (h-alpha modded) - Nikkor 70-200mm F/2.8FL lens on a SkyWatcher StarAdventuer tracking mount.

Sky (Tracked) - A mosaic of two panels - 3 images each for stacking. ISO 1200, F/2.8, 60-seconds each. Integration and initial processing done in PixInsight.

Ground - A mosaic of two panels - ISO 3200 - F/4 - 45-seconds

The entire pano put together in Photoshop and final edits done there, too. ...

"Dawn of Orion" by Skypointer Photography

Ralf Rohner says:
This deepscape image shows the sword of Orion rising over a scenic mountain formation in central Switzerland. The famous Orion Nebula, the Horsehead and Flame Nebula and part of Barnard's Loop are colouring the sky in a stunning way.
Deepscapes are an attempt to take landscape astrophotography to the next level. This image is not a digital art collage of an unrelated sky and foreground, but a real alignment. A snowshoe hike with a mobile deep sky imaging rig to a carefully planned site on a mountain slope was required to capture this scene. Foreground and sky were captured back to back during the same night and from the same tripod position.

Capturing and processing the image required both deep space and landscape astrophotography techniques. The foreground and RGB color image of the sky were captured with an astro-modified Canon EOS 6D and a 200mm lens. The sky image was enhanced with 55min of H-alpha data captured with a cooled monochrome astrophotography camera through a narrowband filter and the same lens. As I used two different cameras I labeled the image as a composite.
