Image Information:  The Pelican Nebula (IC 5070) is part of a large star forming region with large dust clouds obscuring portions of bright ionized gas. The entire nebula is over 30 light years in size and about 2,000 light years away
Processing Comments:  First image with the RC-16 properly callibrated and with an accurate T-Point Model. Seeing was about 1.8-2.4 arc-sec.  Images were collected over a 2 week period along with L, R, G, B, SII, OIII data (see next images).  Processing again minimal, using CCD Stack abd PS for image data stretching and smoothing.
