Large field dark nebula were imaged with a Canon T7i DSLR and lens mounted to a Skywatcher AZ GTi mount or on a tripod. Details are listed below with the targets.
Requirements
Image 70 dark nebulae. There are 35 required objects on this list that you must image. Choose 35 others from the list for a total of 70 to receive your pin/certificate.
The use of publicly available “remote” telescopes controlled via an internet connection is not allowed. Delegation of image acquisition is not acceptable.
“Go-to” telescopes are allowed.
Imaged dark nebulae must be identified by means of an overlay, companion sketch or other method to clearly identify the dark nebulae on the image(s). This is particularly important in cases where the dark nebula may be difficult to clearly identify on the image or more than one dark nebula is present.
Keep a log recording your imaging including:
Object name and number
Date and time of the imaging (local or UT)
Latitude and longitude of your imaging location
Seeing and transparency
Filters used (if any)
Telescope/optics used including aperture and focal ratio
The camera/CCD used, exposure times, film types, image software, number of stacked images, and other information relevant to the image production must also be provided
Include an estimate of how opaque (dark) the dark nebula is compared to other dark nebula and the surrounding Milky Way. This required estimate of opacity should be made on a scale of 1-6 with 6 being the most opaque.
Imaging Locations:
Home 38.631 N, 90.552 W (34 images)
Chesterfield Mall 38.652 N, 90.565 W (now demolished)
Sachs Library 38.662 N, 90.543 W (1000 feet away from the Mall)
Brommelsiek Park 38.723 N, 90.814 W (only three images)
Right:
My original Mall location was #1 in the picture. I later moved to #2 for a better view to the south and west. On October 19th I was asked to leave by security and then moved to the Sachs Library Lot at #3.
The second picture on the right shows the location of my Home and the Sachs Library on a not so dark Dark Sky Map.
Below:
Typical sky at Chesterfield Mall and Sachs Library. Only three stars can be seen in the enlarged image. While the sky is slightly darker at Home, sixty foot tall trees in the backyard prevent viewing from the SE to NW.
Visual transparency due to suburban lighting was never better than 1/5 from any of the imaging locations.
The poor transparency prevented seeing estimation because stars couldn't be seen.
Still, SeeStar imaging did produce results.

There is the concern that a five-minute exposure from a bright Bortle site wouldn't get the job done on dark nebula. I'm also a subscriber to Slooh telescopes. Just to test it out, I did capture a few of the OP's dark nebula with the much bigger Slooh scopes from their dark skies, and the data wasn't much better than I captured here in Chesterfield.
As an example I picked Barnard 145 and used the Slooh Canary Two Ultra Wide Field telescope for a 5 minute mission to compare it with a SeeStar 5 minute exposure run. The results are below.

For fun, here is a wide field that I took back in 2013 from Shannondale, MO with a modded Canon XT and 17mm focal length. I've always liked this picture, and it does show many dark nebulae. Since the camera was modded, much IR shows as red.

Wow!
