Description

Summer 2019 Project

Data adquired from July to September 2019.

H and O has been used in combination of starnet++ to create a starless HOO narrowband image. This HOO image has been processed and finally, added the RGB stars.

Update: Version J has RGB stars taken form narrowband following this methodology:
