No, you won't as they've just been discontinued alas, Datalord and I picked up the last two, at around £12k a time.

That's a brilliant image BTW, and yes, the Helix is desperately low from these latitudes.

Was the RGB only used for the stars or also mixed with the other channels ?

Thanks

Hi Frederic,

In the process I did all channels details separately at first Ha, OIII, Lum, RGB (RGB I did as one from MaximDL).

In  photoshop I used LRGB for the Stars and I had to the Red the Ha also.

Then I took the Ha photo and deleted the Blue and Green color channel from it and add the OIII has the Blue channel. Then I use an action that is part of the Astronomy Tools called "Synthesize Green Channel from Red and Blue" to create the Green color...the beautiful colors you just pop up. It is the first time I use this technic and I was very happy with the results.

 

I hope it answer your qestions

cheers,

Haim
