An attempt to shoot the Vela Supernova remnant. Used the Canon 70-300L at 300 f/5.6, 14 frames of 4 minutes each.
The post processing after stacking was very tedious and took much time, finally I used the
Lonelyspeck method. He has a video with very clear instructions how to do this in Photoshop.
The result I consider rather poor, but you can see at least the blue 'Pencil' NGC2736.
