Description

NEW PROCESSING for my six panels mosaic of North America and Pelican Nebula - NGC7000, IC 5070 and IC 5067 - LRGB composition - Hybrid narrowband palette L=H-a+POSS-II Red R=SII G=Ha B=OIII

Data from POSS-II Survey and David Lindemann

POSS-II Survey (http://www.astro.caltech.edu/~wws/poss2.html) (20 panels of 60x60 arc/min for Red data)

Captured 04.14.2013,04.15.2013, 04.17.2013, 04.23.2013, 04.24.2013, and 04.25.2013 with Takahashi FSQ106ED @f/5 530mm focal length with Apogee Alta U8300 monochrome and Astrodon H-a, SII and OIII 5nm narrowband filters.

28 x 1200s H-a unbinned = 9h20

24 x 1200s OIII unbinned = 8h00

23 x 1200s SII unbinned = 7h40

Total exposure time 25h (except POSS-II data)

Software: MaximDL to capture, calibrate, register, normalize, data reject and combine - Registar for mosaic composition - Photoshop CS5 and PixInsight for color combine and non-linear streching.
