How much time spent on the prep side, capture time, and post production time?
Prep time did not take long. The images are 30 secs for each of the 9 in the slice, times 3,
making it total of 710 secs of exposure , with another 90 secs for dark frame for each of the slices.
Is there any way to get the lighthouse in focus?
Unless I use a single image, or I use an equatorial mount, or a darker sky resulting in shorter exposures,
I doubt I will ever get that lighthouse in focus. I have single image stacks as well but they all suffer the blurry
lighthouse. May be I try to tweak one of the 9 images and see if I can get acceptable results.
What are your thoughts on the results?
One thing I forgot was to use my Bright Star filter to fine tune the focus to infinity.
I will reduce the exposure and increase the ISO to minimize the trailing. I already managed
to make stars closer to point sources in the last image compared to the first image.
I am debating if my HDR technique is an over kill. Please see the image below.
Will there be more attempts?
Yes, but not until February. For us the Milky Way is below horizon between now and February.
I am hoping to get an arc next year.
Thanks.
You are welcome....
