M42 Setting Over the Eastern Sierra: A Return to Astrophotography
It's a feeling many astrophotographers know all too well: the frustration of recalcitrant equipment pushing you away from your passion. After a year-long hiatus battling with mirror collimation on my Newtonian telescope, I was more than ready to get back under the stars. An opportunity arose during a trip to Lake Tahoe, and I couldn't resist.
The Scene: Alabama Hills Under Dark Skies
My journey led me to the Alabama Hills, a spot renowned for its breathtaking landscapes and, more importantly for us, its gorgeous dark skies. Just a short drive from my hotel, the trailhead for Mobius Arch offered a perfect vantage point for some untracked shooting.
Capturing the Cosmos
The image you see above is the result of a dedicated effort to capture the Orion Nebula (M42) as it dipped below the Eastern Sierra. Here's a glimpse into the technical details:
- Camera: Sony A7RII
- Lens: Sigma 18-35mm f1.8 (with Canon EF to Sony E converter)
- Exposure: 7 x 10" @ f1.8, ISO 3200
Post-Processing Magic
To bring this celestial scene to life, I utilized Sequator for stacking the individual exposures, effectively reducing noise and enhancing detail. Following the stacking, I moved to Photoshop for some simple stretches and color adjustments to the stars, ensuring the majestic landscape remained untouched and true to its original beauty.
This shot represents not just a beautiful image, but a personal triumph – a welcome return to the immersive world of astrophotography. The vibes are indeed perfect, and I'm thrilled to share it with you all!
