Nikkor Lens -> Atik 314L - No Support Needed - V6 with a little help to point the sky regions.

Adapter to connect directly the Atik 314L to all Nikon lens for large field deep sky images.
Without tracking i'll start to make 300-500 images with 2 secs exposure then stacking with some free DeepSky stackers.
Cinema 4D Scene provided, almost procedural all.
Someone know what cause the defect that you see in the photo?
