Lagoon nebula-Attempt 3

Did this one last night.

10 x 30 second light frames at ISO 1600, 10 x darks removed, stacked and processed in deep sky stacker.

Celestron Nexstar 11, equatorial wedge alignment, Canon 400D, prime focus on a waxing gibbous moonlit night. Also used one of those ambient light filters on the camera adaptor. The resulting shot was a little darker, but way more detailed.

Removing the darks seems to have made all the difference.

Conversley, I opend the shutter on the same target and just let the telescope go with it's own tracking for fifteen minutes. (Fell asleep) Have a go at what it did! (Second image) I have no idea how to refine this tracking. I'm thinking when I get the ED80 on top, I will have to guide manually.
