Description

This seems to be the limit of my current equipment and light polluted backyard location. Almost 4 hours exposure time with the Nikkor pre-AI 135 mm f/2.8 stepped down to 4. Single picture exposure time of 150 seconds at ISO 800. The single images are bright as shot in daylight. It is very hard to remove the background light pollution, and there is only residual luminance of the nebula left. I had to crop quite strongly, but you still see this background in the top left corner. I need to go to the mountains (but it is still too cold) or use a light pollution filter.

Nevertheless it was fun to shoot and process, I am still lerning alot and it is wonderful to get a picture of a deep sky object which you do not see at all with eyes or even binoculars.

Best wishes from Lausanne,

Jan

B: Reprocessed from scratch. Could not control the color problems at the borders, so I cropped quite extensively. Used a very stringent noise reduction workflow in PI and a protected stretch. Finetuning in Lightroom. I think the you can see the witch's laughter a bit better in this version.
