My first time shooting at Hurricane Ridge. While the setup was a bit
crazy with cars driving in and out for the sunset, by 8:30pm the
parking lot was deserted. I only shot for a bit over 2 hours because
the moon was really bright and this was more about how to deal with
the moon.
Here is the Heart Nebula:
And the Ghost Nebula which is cropped:
On the Ghost Nebula, I did a screen grab of the asiair with
annotation:
One can see that IC 63 is centered.
I did not do the screen grab on the Heart, but I did run it through
astrometry to get the annotation:
Here I should have realized that the Soul nebula was being cut off
and I should have moved the center, as well as rotated the
frame. Something to remember for next time.
