Bubble in two color modes

Hi Folks,

I'm posting an image of the Bubble nebula in RGB and HaRGB to show how adding H-a adds some detail and maybe detracts from the ascetic appeal.

This first image, a pure RGB, was taken by Anthony Ayiomamitis in Greece with an AP160 refractor and ST2000 CCD (Anthony likes diffraction spikes so these were added via string across the aperture). It shows the bubble as an ethereal bubble hanging in space, almost 3-D like.

This second image adds H-alpha detail taken by me with an AP 160 refractor, STL11k and Baader narrow band filter, added to an image taken by Gilles Cohen in France with an AP155 refractor and ST8 camera(most of the HA data is Gilles'). This is a multi-national effort.

This image shows how H-alpha seems to cut through the mist of the bubble, rendering the insides in more detail, but making it look somewhat more flat, no?

In the future I will add closeup data of the inside of the Bubble taken with my AP 10" Mak-Cass. It shows some tiny protostar bubbles within the bright twisty thingamajig - but more on that later after I've had a chance to process several hours worth of H-a data.

Way cool images Roland!

Certainly the Ha adds impressive detail. The color of the bubble in the RGB is impressive. I con't decide which I like best - I just keep cycling back and forth between the two.

Isnt there some kind of law that prohibits putting diffraction spikes on an image taken with a beautiful AP triplet? If there isnt, there outta be. grin

OF course, I say that in jest, he can do whatever he likes, its his image. grin
