        CSOG Interim Update + new editions

        It will probably take me a month, but an interim update to CSOG is coming soon, along with 9 new editions.

        New editions

        The interim update will bring 9 new editions:
        • Struve-Straka nebulae
        • Dorschner-Gürtler nebulae
        • Van den Bergh Reflection Nebulae
        • Rojkovskij-Kurchakov nebulae
        • Bernes Bright nebulae
        • Neckel-Staude nebulae
        • Peimbert-Bátiz & Peimbert-Costero planetary nebulae
        • Merrill Planetary Nebulae
        • Herschel Regions
        The information in these new editions has been incorporated into existing editions where applicable. Lots of tweaks were made to existing content, objects added and errors corrected.

        This will be a huge update to CSOG, adding further unique content that cannot be found in any other publication. I am pleased to be able to release it less than a year since publication of CSOG 3.0.

        Coming soon...

        Future updates to the Clear Skies website will include:

        Weekly updates
        Monthly updates
