Went out to the dam at wyaralong yesterday and managed to get 10 frames of 300 sec on the horsehead. I could have gotten A LOT more but i had issues with dust on the camera which really demoralised me. Turns out it was easier than I thought to remove using the brush tool on photoshop. Oh well.
As with all horsehead images, alnitak is a bit wonked. I'll need to work on making it better.
