Description

Image of two objects in the outskirt of the SMC. It has some combination of problems, gradient plus background homogeneity but, it is the first go.
I believe there are two problems, one is the variation of the background sky while taking the set of images, particularly the first set, just after sunset, and the second is that complex fields, full of objects, tend to be more complicated in stitching. 
So, I will prepare another analysis of the background to do the match.

Title: More data and a few issues solved

Description: New stitch parameters and removal of the sort of gradient using DBE. 4 more hours of data and slow stretch, one go using maskedstretch and then slowly using histogram and curves. Still some aspects can be improved with the same data, but maybe next time I shall try NB images.
