Consistent equalization on set of images

I want to use exposure.equalize_adapthist() on a set of images, but a 
defined part of each image occasionally will have a very bright object in 
it, which I would like to ignore when calculating the equalization. 
Currently, the images with the very bright object are much darker than the 
images without it.

Really, one of two solutions would work, but I don't know how to do either 
with scikit-image:
1) Calculate a histogram equalization for the entire set of images and 
apply the same equalization to each one
2) Mask the area with the bright object, calculate the equalization of the 
rest of the image, and apply that equalization to the original image.

Are either possible? Thanks!
