Hello Glenn,
Thanks for sharing! Very nice image.
I too, just recently started to capture the Elephant Trunk Nebula but still need to process the images. I use a quad narrowband filter with a ZWO ASI2600 color camera on a 130GTX. Did stacks at 240, 360, and 720 seconds. Here in California, even with a nearly full moon I got decent results with the filter in place. Now I need to start processing in PixInSight.
Having your image as a reference is helpful.
Best,
Alex
