Description

This is to test a prototype filter made by STC:
http://stcoptics.com/en/astro_duo/

Ver.B is the image taken with the filter, containing 30-minute of exposure.

Ver.C is the image taken without the filter, also containing 30-minute of exposure.

Ver.A (final) combines both.

Ver.D is developed from Ver.A. It's a reprocessing in 2020 based on the latest taste of mine.
