NGC 6357 The Lobster Nebula

While all those lucky buggers were swilling beer and lapping up all those awards in Parkes...I was out where I belong .. in the cold grabbing data

This is the first of two data sets gathered Friday and Saturday nights. The good thing was the seeing was excellent for a change and remained so for 1.5 nights woohoo . The guide star hardly moved all night and went for hours without a single even random excursion, outside the 1 pixel radius circle in Astroart (1 arc sec) = heaven.

The new camera purred like a pussy cat without missing a beat too, the air reached basically 100% humidity in the end too (foggy and everything was soaked, including me!) but with no sign of CCD widow fogging, a real pleasure to use.

Here is the usual data set of images of The Lobster Nebula in Scorpius. To see the largest file in each case, scroll to the bottom of each image page and click on "original" in the other sizes menu.

I think the Ha only version is my favourite actually, lots of fine wispy details showing up well in the Ha contrast.

Enjoy

Mike
