Description

NGC 7380 Wizard Nebula - OSC using L-eNhance

Though this object was imaged before, I had never done it with the ASI071MC OSC camera and the L-eNhance filter. Though a pleasing image, the blue/oxygen regions were less pronounced than when using a mono cam with narrow-band filters. But upon comparison, this region appears with the same intensity as other examples of OSC users. Perhaps an L-eXtreme or L-Ultimate filter within narrower bandwidth would also yield some improvement here. But an OIII filter with my ASi2600MM would be expected to show this region more readily, especially if more integration in that channel was collected relative to Ha data.

Initial WBPP results in PixInsight using default settings for Local Normalization were disappointing showing complex gradients which could not be removed with ABE or DBE. However, redoing the registered frames with NormalizedScaleGradient and its default integration settings produced a much more even and easily processed background.

Details within the nebula were made more pronounced by extracting a luminance layer, performing deconvolution and adding back using LRGB combination. DarkStructureEnhance provided some shading and a slight 3D effect within the dusty regions.

Subframes acquired during the nights of August 12, 17,1 8, 23 and 24, 2022.
