We've had clouds and clouds lately. I'm starting to chew on old data. Two are new images to the blog, however.
All of these images were taken with the SXVF-H9C.

This image is only 5x20'. It was taken very early in the morning on the 20th of July. I thought I was going to get some more time the next night, but clouds moved in. So I was able to get no more luminance and took no color data. Fortunately, there are many images of vdb152 around the web. The color data you see above was donated generously by Bob Fera. The Feras' lovely image, which I think has the best color balance of any for this object, can be found here (just scroll down through the great images till you find it). Through the magic of Registar and Photoshop, I can superimpose just the color from the Feras' image over my own grayscale image. Thanks to the Feras.
Here is my data in grayscale:
