About this image

A total of 13-hours of exposure integration taken in 2021, 2022 and 2023. This multi-year project is allowing me to acquire significant total exposure integration for this summer target, in the UK.

The image has been cropped by about 25%.

As the integration time increase then the Ha filaments in the nebula increasingly resolve into multiple finer filaments.
