Tulip Nebula Area: Narrowband Images

The tulip nebula is the bright object on the left, also known as SH2-101, cataloged by astronomer Stewart Sharpless. Sharpless created a catalog of HII objects, many of which are good but challenging targets for amateur astronomers. The natural color technique is described on my astronomy workflow page. I really like the pointy dark nebulae on the right part of he image.
I like the presentation/orientation here, but it is mirror reversed which makes identifying things a bit of a challenge! Barnard 147 is the top-right pointy area that aims mostly right, and B144 seems to be a catch-all for general dark areas in the frame. I believe LDN 858 must be the pointy area in the far right. Here's a link to a tulip image that identifies some objects. I believe the bright stars right middle are NGC 6871, if this page is right ;-) (mouse-over to see the ID). The dark blob top center/left is B146. So, key dark nebula visible include B146, B147, B144, and LDN858.
This narrowband image features the Tulip nebula and the surrounding area. It's a slightly different version than that shown on my Wimberley 2015 trip page here. I really like the pointy dark nebulae on the right part of he image.
I was inspired to tackle this area by Don Taylor's excellent image shown here. I need a lot more exposure to come close to what Don accomplished.
Image Details: This is a Hubble Palette narrowband image, composed of 6.5 hours total exposure: 37 * 5 min H-alpha, 18 * 5 min SII, and 23 * 5 min OIII. Image captured at Starry Nights in 2015. AP 900GTO mount, SBIG ST-8300 camera along with the Takahashi FSQ-85 "Baby Q" telescope (without the reducer). My processing techniques and workflow are discussed here. I used the Carboni "Enhance DSO and Reduce Stars" action on this image, which is the primary difference as compared with the version on the Wimberley 2015 trip page.
