Subject: [AZ-Observing] M16 - Hubble Palette
With a portable imaging rig and the difficulties that come with deep sky
imaging during the monsoon season - M16 had always been at the top of my
list of things to image. Until this year, I'd not been able to do it. Now
that I have my equipment set up remotely, I was able to start imaging this
target as soon as it was getting high enough above the horizon as far back
as early May - even if it was just one frame per night. I was able to
finish the image in mid-June and started processing.
This image is a total of 37 hours of exposure time shot in the standard
Hubble palette:
Red = Sulfur II filter (3nm) - 12 exposures @ 60 minutes each
Green = Hydrogen Alpha filter (3nm) - 13 exposures @ 60 minutes each
Blue = Oxygen III filter (3nm) - 12 exposures @ 60 minutes each
All images were captured with an Explore Scientific ED152CF f/8 triplet and
an SBIG ST-8300 CCD camera in Benson, AZ. All image processing from
calibration to final post-processing was done in PixInsight v1.8 RC7. I
was really happy with the end result considering that by the time I took
the last few frames, thermal noise was becoming an issue with the
encroaching summer temperatures.
Comments and criticisms are always welcomed. Thanks for looking.
