Description

An open cluster in Cygnus often overlook as buried in the sea of nebula. A bonus open cluster NGC 6989 also appears but does not plate solve in the upper left coner. This is an LRGB image with blended Ha. I'm waiting for an Oiii filter to come in, so no HOO or SHO till then. But I'm enjoying the RGB star colors in the meantime. I captured this in one night from Mt Pinos with fairly good seeing. Guiding with the ASIAIR PRO was 0.7 to 0.5 RMS. I worked on my camera's tilt plate. I have slightly better shaped stars in the top corners (cropped the worst out), but now the top left is slightly out of focus...more work and trouble shooting to do.
