Description

A crop of the last shot around the Prawn nebula IC4628

-------------
Thanks to SADR Team who welcome me onboard their Sadr association, and the 2 astrophoto setups in Chili. Southern Skies and its wonders just open to me !

My first Shot made with Sadr team in Chili with Fabien Trébuchet and Patrick Delay
After ten nights spaced out over two months, and hours of treatment, here is a first version.
Note also the pretty "blue-eyed fox" on the top right.

Mosaic of 4 tiles with TS 71mm 347 focal at 4.9
4 images of 25xLx300s + 30xRVBx120s + 50xHax300s

Fabien and Patrick => preprocessing,
Fabien => special thanks to him, who did all the mosaic assembling in drizzle mode : even with a powerfull PC, a pano x4 drizzle takes a lot of time , Fabien told us ;-)

The result is really fabulous : 4 frames at 16 millions pixels for each with x2 in Drizzle , it makes a final size of: 17193 x 13009 pixels, so it is around 223 millions pixels !

I share with you a REDUCED version at 5000x3788 pixels
