Please note I have gone back and reprocess the original image with new learning and understanding.


I first took one night mix of the three filters O3 S2 Ha to see if it looked promising. I have been chasing cool to run the camera at -10c I have to get a 25c start. The one night looked very promising so I added an extra nights worth of shots to each filter to get close to 100 shots each.

My first shot showed my Flats was not very good there were some Lens train faults the showed up in the processed image. so I got up at 5 am in the cool of the morning to retake a whole new set of flats Restack the whole lot and start all over again. you can see the big dot in the very center and the normal amount of vignetting you see on a telescope around the edge.(darkened corners) its a case of retaking the whole lot all over again...but the shot below shows you what is removed from the stacked shots to get a clean shot for each of the three filters.



The Narrow band filters shows up a lot more of the Nebulas than a normal one shot colour camera. This is my first real shot into this world a lot more work but very interesting results.


You know this shot but not taken like this.
