Hi all,

ngc7789 is one of my favorite clusters to look at visually. I've hunted it down with a 70" and 100mm reractors and 6,8, 12 & 18 inch reflectors and it always provides a great view.

I took this image with a Televue Gensisis SDF and a ST10XME its a RGB with the Lum made up of the red and blue channels, 15 mins exposures each channel. The image was taken with a near full moon out and the gradients were wicked.
