Thanks Glen,
great advise re the imaging exposures.
I took many images during the night, and varied the exposure
times as well as ISO.
Agreed, it does produce a very bright core, especially at such a
high ISO for that long an exposure.
I seemed to have had a `sweet spot` of 10 seconds at ISO 1600,
that night, but wanted to see what I could get the camera to provide over every available setting,
as it was the first time I had used it.
I think you are correct, it would have been a gust of wind that
gave me the unusual image, as there are none to be found in other
images taken.
Though it does look like a fleet of starships or such in flight across the sky...…?
The Celestron Skyportal was doing a fairly good job keeping things
where they should have been, with only a slight amount of drift occurring.
A word of thanks to Turbo Pascale (Rob) and Startrek (Martin), for their posts on finding Solar Noon,
it was a great help with alignment.
