David Rosenthal:



Here is my submission for August: NGC6992 The Network Nebula

This is a RGB = Ha (Ha*OIII) OIII Bi-Color process shot over 4 August nights from my LP'ed back yard in Northern NJ.

12*1200 seconds 5nm Ha [ 4 Hours ]
16*1200 seconds 5nm OIII [ 5.33 Hours ]

Borg/Pentax 125SD with Oasis #7878 Tripplet FR/FF
Losmandy G11 Gemini AP Wood Tripod
AstroDon 5nm Ha and OIII Filters
SXVR-H18 / SX Wheel / SX OAG / SX ExView Guide Camera
Mount Control, Guiding, Capture, Calibration and DDP in MaximDL
Processed in PSCS5 X64 with Noel Carboni's Actions and GXT



Mike Wiles:



Date: August 2012
Location: Goodyear, Arizona
Sky Quality Suburban Light Pollution - ZLM 5.2
Telescope: Explore Scientific ED127CF Refractor - 127mm f/7.5 Carbon Fiber Triplet
Mount: Astro-Physics AP900GTO CP3
Camera: SBIG ST-8300m and SBIG FW8-8300 filter wheel
Guiding: SBIG ST-i Mono and SBIG OAG-8300 off-axis guider
Exposure: 7 hours (Ha: 7 x 30 min, OIII 7 x 30 min)
Capture: Maxim DL 5.18
Calibration & Processing: PixInsight 1.7

Looks like it's Veil Nebula month. At this summer's Grand Canyon Star Party a friend and I were looking at Pickering's Triangle around midnight from the veranda of the North Rim Lodge through a 20" Obsession. I was so blown away by the detail in the background around Pickering's Triangle that I knew I had to image it soon. This is the result of that effort. Image was shot as a bi-color narrowband by mapping H-Alpha to the Red Channel, OIII to the blue channel and then H-Alpha and OIII were blended at a ratio of 50%/50% to generate a synthetic green channel. Processed entirely in PixInsight. A larger image can be seen at Astrobin.



Please note that voting will conclude on September 8th at Midnight EST.

Many thanks to all who took part in the contest!

Thanks David. I really like yours as well...especially the deep red "bubble" running horizontally across the image above the nebula.
