Description

30. Oct-2021. Update, got  two evenings with reasonable astro weather conditions to take some color frames with different 2" filters :-)

The colors in the planetary nebula come mainly from the Quad Band 2" filter.

Notes:
Version "C" is a desaturated color version.
Version "D" a WF version of the SH2-188 Nebula. Total exposure, L-RHa,G,B: 48x60, 16x120, 13x300, 15x120, 16x120sec.


Due to the terrible astro weather conditions in CPH, DK lately I have decided not to wait for 'exposure time enough' status to show "final" images.

It can take years to get enough clear nights/sky to show "final" images, therefore this Ha picture submission even it's not what I call a "final" image :-)

My home build observatory is placed in my front yard/in the "red light" pollution zone, have a look here,
