Scope: Explore Scientific MN152 Maksutov Newtonian at f/4.8, Location: Pine Creek, CA,  1 July 2016  Camera: ST8300M (Baader Ha LRGB filters)

Exposure: Exposure:  14 x 8 min (1x1 bin) exposure with IR/UV Block filter, 11 x  10 min (2x2 bin) exposure with H-Alpha filter, 8 x 4 min (2x2 bin) RGB exposures.

Processing: Data Collection -  Sequence Generator Pro (as FITs).  Calibrated, stacked (Kappa Sigma Combine) - Deep Sky Stacker. LRGB channel registration, equalization, and gradient removal - Astroart.  Curves, Levels, RGB combine - ImagesPlus. Luminance Layering, final stretch, and finishing  - Photoshop.  RGB calibration - eXcalibrator. This image is a  RGB combine with Luminance layering.  Color saturation in LAB color.  The H-Alpha filter exposure was screen blended into the IR/UV Blocking filter exposure stack and used for the luminance layer. Images processed at 3352 x 2532 resolution. Final Image size is approximately  2000 x 1500.

North is to the right in this image.  Sharpless 88 is the large red nebula on the right; Sharpless 87 is the one on the left. Just above Sharpless 88 are two small nebulae - one blue , one red - both associated with Sharpless 88. The blue nebula is Sharpless 88b2, the red is known as Sharpless 88b1. There are several dark nebulae in this field - some identified and some not. Of the ones cataloged by Dobashi, the 5 larger ones are notes in the annotation. These objects  are identified in the annotated image.   Horizontal FOV is 85'

Image center is approximately - Equatorial 2000: RA: 19h 46m 28s Dec: +25°02'36"
