It has been a long wait since April, when I made my last images, through abysmal spring weather and the bright summer nights.

Initially shot 4 hours of the Crescent Nebula on Saturday.  Star background had a reddish tinge, which I removed by making an inverted mask around the nebula, and then toning red down.  While it made the nebula stand out fine in a more 'clean' looking image, a check of some other Crescent images revealed the entire area to be full of Hydrogen clouds.

So more data needed; added another 3 hours Sunday, for a 7 hours total, which brought out the Hydrogen much better, to produce the attached image.

Equipment as per signature.  The 200PDS was used for this.

Crescent Nebula is Caldwell 27 / NGC 6888
