  1. 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.

  2. After 9 months of research and countless conversations with fellow astrophotographers, I finally pulled the trigger: the WarpAstron WD-20P. Direct drive instead of encoders, 22 kg payload, open OnStep ecosystem, and guiding values between 0.3" and 0.5". The mount is the foundation of everything — and this one is built to last.
    Part 1 of 3 is now live on the blog.

  3. 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.
