About this image

Known emission nebula in Cepheus, commonly called cosmic question mark, also resembling a mysterious dark cave

Data from 2021 reprocessed to which are added new ones also obtained on those dates with the Optolong L-eNhance duoband filter, adding a total of almost 21 hours of integration, which translates into a higher quality of detail and chromaticism.

Being two filters considered double narrow band (Ha and OIII), it has been processed as a typical RGB, highlighting its special characteristics, of course.

Taken on the nights of October 6-8 (L-eXtreme, 124 frames) and October 12-14 (L-eNhance, 125 frames), 2021
