    Processed my friend Lee Nelson's image of NGC 2244 recently, which he captured with the amazing Altair Astro Hypercam 294c ProTec with the Altair Tri Band filter. What a camera! Just 3 hours data

    Mein Highlight des Tages: wenn Vollhonks, die einem Vollidioten in den Arsch kriechen, der nicht einmal die Siegermannschft des Super Bowl korrekt verorten kann, sich über einen Programmierfehler lustig machen.

    My visual mag from last night was 1.60 (robust mean of 13 observations). That is 0.03 mag dimmer than the robust mean of the 5 previous nights (n=83, 0.8σ).

    I ❤ StarNet++ Do y'all use it? 🤔 I have found it to be an excellent way to quickly remove the stars from my astro-images! If you haven't tried it yet (you should, it's free). Here's how:

    Flaming Star Nebula. In this version the blueish star in the center of the image (AE Aurigae), a runaway star originally ejected from the Orion region millions of years ago and responsible for the emission nebula, shows its brightness very well.
