This very small cloud failed to pick up anything using a hydrogen-alpha filter so this appears to be a small molecular cloud. As you can see in this image there are similar objects like SH2-70 around the area. However, a larger telescope can be used to pick up a little more structure. This is an extremely faint object so you will need a lot of exposure time, mainly using the RGB filters. I used a clear luminance for the black and white image, but did not use it for the color because it tended to wash out the color. The red filter seems to pick up a little more than the green and blue, but the black and white tends to show more contrast.

Although usually classified as an HII region, this peculiar high latitude nebula, also called LBN 102, looks more like a dust cloud in this image, and indeed this object is in the same direction as the small molecular cloud [CB88] 124.
