    Messier 1 the Crab Nebula

    Messier 1 the Crab Nebula

    The Crab Nebula, captured on 17 and 18 November, 45x`120s each RGB and 14x600s Ha. Esprit 150ED, ASI1600mm, AZEQ-6. Processed in Pixinsight and Photoshop. I tried a number of different combination methods.. Top left RGB, top right RGB plus Ha using Pixinsight NBRGB script, bottom left RGB plus Ha as luminance, bottom right RGB plus Ha with Ha as luminance. I tend to prefer the top right one. Could do with some more data but with the moon and cloud about it'll have to wait. Thanks for looking Dave
  5. Maybe dithered hot pixels not being rejected when you stack... I'd just calibrate with matched darks, experiment with rejection and see what happens. If you weren't aware with the ASI1600 its important to use exposure, temperature, gain and offset matched darks. Dave

    It's going to be a long, cold winter

    But in a fridge the beer remains unfrozen.... and drinkable!

    I’d keep the beer in the fridge next time so that when it all works you can celebrate with one ... good luck and let’s hope it does

    Will it Buff Out?

    Was anything showing? Did it calibrate when you pressed the green button?

    PHD2 guiding

    I’m sure you have but, have you clicked on the green button to initiate guiding... your screen shot says ‘looping’ and a star is selected .. green button turns black when guiding and it says guiding where it currently says looping.. Dave

    Will it Buff Out?

    Hi, I wonder whether shorter guide exposures would improve that, my AZEQ-6 runs best At 1 second exposure Dave
