LBN468 - more northern dust

LBN468 is from Lynd's catalogue of "bright" nebulae as opposed to the LDN dark nebulae. This field also includes some LDNs and also a bunch of Herbig-Haro objects. The most famous, but still not very well known, of these is a bipolar reflection nebula named after its discoverer, Gyulbudaghian's Nebula. It is also known as Herbig-Haro 215 and is the small fan-shaped object at around 4 o'clock. It is a variable nebula and changes significantly in appearance over relatively short periods of time. There is some interesting detail in this area at 2x drizzle resolution that I'll post when I get a chance to process a close-up version.

Captured at SRO in California:
Scope: FSQ-106ED
Mount: Paramount ME
Camera: QSI683
Filters: Astrodon Gen II LRGB
Guiding: QSI OAG + Lodestar
Image scale: 2.094 arcsec/pixel
Exposures: 34x900s L, 15x900s R, 16x900s G, 15x900s B (20 hours)
Processing: PixInsight 1.8

As usual, I'm not completely happy with the processing. These dusty ones I find particularly difficult. Happy to entertain constructive comments, thanks...

Cheers,
Rick.
