Description

This is my first attempt at enhancing the Trapezium Cluster in M42 by combining 120s exposures with 10s exposures. It is actually straightforward in PixInsight using HDRComposition.

This evening the moon was a few days old and set very early, so it was a moonless night.
Average to below average transparency.
Average seeing.
Temperature dropped to 0C during the night, lots of dew and frost buildup on my equipment.

In addition to the 120s subs I took 105x10s subs for a total integration of 17.5 minutes at this exposure, along with 50 darks.  I will repeat this process and collect much more data once I fix my setup issues (poor collimation, non-optimal guiding).
