How to use CRS for bbox that is not supported

Not at the moment. We will record this on the list of feature requests and come back to you once implemented. We cannot commit to the timeline though.

You might already be aware but Sentinel Hub itself does support EPSG:3035, just sentinelhub-py doesn’t (yet).

The support for any custom CRS has now been added to sentinelhub-py. Now it is possible define an area of interest in a custom CRS like this:

from sentinelhub import CRS, BBox

my_bbox = BBox((3000000, 3000000, 3005000, 3005000), crs=CRS(3035))

At the moment this is on develop-3.0 branch and will be released in version 3.0 on Monday.
