Title: Attempt to enhance fine Ha details for wide angle image of SMC by continuum subtraction using the R exposure obtained earlier

Description: 40min of integral Ha exposure of the Small Magellanic Cloud (SMC) with immediate surroundings captured remotely using Telescope #4 (Nikkor 200mm f/2, FLI Microline 16200) system of ChileScope observatory on Nov 22. 2020.

Continuum suppression applied using 17% of the R component of the image [1] (15 min integral exposure) obtained with the same ChileScope #4 instrument on Oct 7, 2020. Stars were not eliminated from the images intentionally to give plate solver a chance.
