  1. Messier 106 shines as a magnificent intermediate spiral galaxy in the constellation Canes Venatici, lying 23.7 million light-years from Earth. This large galactic system reaches its highest point in the night sky during mid-March, offering Northern Hemisphere observers their best opportunity to witness this distant cosmic wonder at astronomical midnight.

  2. The Hamburger Galaxy, NGC 3628, is a magnificent unbarred spiral galaxy located 35 million light-years away in the constellation Leo. Seen edge-on from Earth, its distinctive shape and dust lane give it its appetizing nickname. This distant spiral reaches its annual culmination at astronomical midnight in early March, making it a prime target for northern hemisphere observers during spring evenings.

  3. astrocamp planner

    Planning my astrophotography sessions used to mean juggling Excel spreadsheets. I turned one of my own planning files into a WordPress plugin: the Astrocamp Planner.
    Right now, you can use the plugin on my webpage but you can not install it on your own wordpress.

    Feedback, bug reports, and suggestions are very welcome.
    Here on mastodon or as a comment on the blog.

  4. Five clear nights during an unusually long stretch of good weather yielded my deepest and highest-quality image of Messier 101, the Pinwheel Galaxy, to date. Three sessions used the UHC filter on the RGB sensor, with two more marking the first light of my new ultra-narrowband H-alpha filter.

  9. New blog post: How to calculate the correct ADU target for flat frames

    Flat frames correct vignetting, dust shadows and uneven illumination. But what ADU level should you actually aim for?

    The answer depends on your camera's bit depth and offset value. The formula: ADU Target = Offset + (Max ADU - Offset) x 0.50

    Examples for 12-bit, 14-bit and 16-bit cameras included.

  10. Sh2-171 – The Question Mark Nebula in Cepheus. A two-panel mosaic covering over 100 light-years of active star formation, powered by Berkeley 59 — a cluster just 2 million years old. Its O5V star BD+66 1673 burns at 45,000 Kelvin, sculpting the dark pillars visible throughout the frame. Processed in Hubble Palette (HSO).

  12. 📸 NGC 6946 and NGC 6939
    This deep-sky image shows two cosmic neighbors in Cepheus: open star cluster NGC 6939 at 5,600 light-years and spiral galaxy NGC 6946, The Fireworks Galaxy, at 22 million light-years. Over 68 hours of exposure reveal stunning detail and faint dust lanes.
