This was a bit challenging after 3 years break. I simply didn’t take the moon into account… 🙁 I started to capture the Dark Shark Nebula a few days ago when the moon was already visible from midnight. Bad idea…Even at 4° altitude above horizon the Moon reflects too much light to capture dark nebulae, […]
My first shot of the Propeller Nebula in the “nebula-rich” Cygnus region. 2h21′ integration. Captured on my balcony. 2x drizzled, resized to original resolution (50%). Details Propeller Nebula cropped:
Drizzle was originally developed for the NASA’s Hubble Deep Field observations. It provides a flexible and efficient way of combining dithered data, preserves photometric and astrometric accuracy, optimal signal-to-noise ratio and approach the best resolution that can be reached with linear reconstruction. (from “A method for the Linear Reconstruction of Undersampled Images” by A. S. Fruchter […]
Finally a clear night to start shooting after 3 years pause… The Star Adventurer & Co. is working fine so far 🙂 Details Cropped Fireworks Galaxy
I shot this M109 back in 2018 but never processed the raw data. A good practice to become fit again after more than 3 years pause 🙂 Details
In PixInsight 1.8.8 a few new features are available for image stacking. Since I’m using flats now, its time to update my previous Stacking in PixInsight tutorial. All following CFA settings are suitable for CMOS sensors like in my Canon EOS 70D, using the Bayer matrix filter (RGGB). Select the proper settings for your camera […]
I created a little time lapse of the Lunar Eclipse. Shooted at 50mm and 560mm focal length.
First image: 22:04h Last image: 00:08h Details
It was a fantastic eclipse 🙂 Details
First preview from the Lunar Eclipse 2018. 22 images stacked (each 4s, at 560mm). I did more than 1000 images… so I have a lot to do this weekend 😉 Details
