Description

This is NGC 6357 and the region around the head of the lobster nebula.

Imaged in Ha Oiii and combined using perceptual representations of each band and a boost of x2 on the Oiii channel because there is only a small amount of Oiii near the center.

EdgeHD11 f/7 guided with OAG and MetaGuide.

21x5m Ha + 20x5m Oiii

No processing other than slight background color adjustment and application of levels in PhotoShop, with slight cropping.
