So I have always wanted to image this but it is really low and we have high trees so I actually never though it was possible at all. Just for giggles after finishing another object I pointed the mount and camera in the direction of the Helix and it was there just above the trees. It soon disappeared however I did get 14 minutes on it before going away. If it were visible for an hour it might be worth imaging with larger setup but for less than a half hour this will do. Actually I was happy to get anything.
I cropped it heavily and was very creative with new noise reduction as it was bad, not to mention the gradients. Also, there were no support frames for this either - not even darks so I had to remove hot pixels by hand. If you are a pixel peeper see how many you can find. I decided to make a gif of the 14 subframes so you get an idea how close the trees are to it - the gif is my first ever attempt and is low quality.
