Description

First try with the Star De-emphasizer script for PixInsight, inspired by the Adam Block technique. Helps enormously to isolate star colors while muting very dense star fields.

RASA 8 continues to show distorted corners; we intend to try some possible solutions in the near future, the distortion plays havoc with mosaics.

I think the bubble nebula was the first object that got me interested in narrowband imaging - we still have yet to get a good one in narrowband.

The nova 'V1405 Cas' is the orange star at about the 9 o'clock position from the bubble.

A note about stacking with Deep Sky Stacker -
With so many subframes, I had to stack them in groups (one stack per night) and then stack all those results. Trying to do them in one go was too problematic - no fault of DSS. On Windows I had to set up Microsoft Defender exclusion folders so as not to interfere with DSS.
