Dr Druckmüller discusses the need for flat fields for normalize images in his instructions for TSE 2009.

I am familiar with taking dawn/dusk flats but this is something else altogether.  Other than flipping a piece of white cloth over the end of the scope, does anyone have a clue how to make flat field images right after the eclipse?  It seems that anything one would do would have very poor uniformity.  I have an EL panel but that would be a challenge to use in middle of the day.

Miloslav Druckmüller advertises that he uses the following software: Astro D3F 2.0, PhaseCorr 6.0, LDIC 5.0, Corona 4.1, Sofo ACC 6.1. Has anyone any idea how to get hold of any of this software? Thanks.

 

Cheers, Peter

You can't and you don't need it either.
You can create a better looking more natural composite using Fred Espanek's old tutorial. He references a link to the original article in his 2017 Eclipse blog. My two cents.

That's a beautiful image, but looks less like a solar eclipse as it does the Moon on fire.

Not really. During the 2017 eclipse I had a brief glimpse of it through one of my telescope's finder scopes and a 5-inch Newtonian.

The view was close, if not almost identical to, Druckmuller's eclipse images.

IMO, Druckmuller's approach comes closer to what an eclipse looks like through a telescope, compared to Espenak's naked eye routine.

Here you go:

Russel Brown's eclipse techniques using radial blur and layers.  Second tutorial down.

Here's what I came up with using my images.  Neglected to use RAW unfortunately so not the best it could be, but for never having done any kind of total eclipse processing, I don't think I did too bad.
