Picture taken during my Namibian astrotrip in May 2015.
I do like this part of the milky way, which contains a lot of tiny and weak deep sky objects. I had seen very nice picts on the net of this frame, so I tried on my own to picture this area. I went for a LRHaGB combination which was not very easy since I ve decided to shoot Ha channel in binning 2 (usually I do Ha subs of 10min in bin 1 but guiding issues force me to limit exposures to 5min) ... a mistake I wont repeat in the future !

Since Ha was in bin2 I was not able to blend it directly into the luminance data.
After many iterations in Pixinsight (using both HaRVB script and LRGBComb process) I achieved this compromise.

Thanks for watching, and if you have any tricks to improve the final result I would be glad to test it !
