My wife (Denise) and I had a the great fortune to experience last week's eclipse with a fine group of eclipse chasers on the beach in Western Australia.  This was a short eclipse of about 48 seconds and we were a bit off centerline.  This was my 6th successful eclipse and each is different - shorter ones like this can actually be the most beautiful!

The flower shaped corona was a treat and the largest of the prominences were easily visible to the naked eye.  One interesting feature of being a little off the center line is that I captured a diamond ring effect 90 degrees from 2nd and 3rd contact !  That will be in a future version.

From an imaging standpoint I was more focused on short exposures to control the bright chromosphere that the small Moon would reveal.  I also expected significant prominence activity due to the Solar cycle.  Also, with the Moon so small, the bright chromosphere was likely to bleed in too much to try to  capture Earthshine. 

I traveled with a lighter setup than in the past; Sony A7R4, Sony 100-400 lens, and a Fornax tracker.  Unlike my old Canon equipment, I discovered that there are no full eclipse automation programs for Sony cameras.  So this was done with a manual shutter release and an auto bracket of 9 images from 1/3200-1/13th of a second at F11.  I managed 3 sets between diamond rings and all 27 of those are stacked here in this image.  I used a low ISO of 320, which I understand is one of two "native" ISOs for the IMX455 chip.  I've learned from testing that this sensor (as most are) is ISO invariant so while it doesn't look like a lot on the back of the camera the data is there when stretched.  Keeping the ISO low allows the highlights to be captured with the minimum of pixel saturation.  This is also how I'm shooting Milky Way shots these days and it is great for retaining star color.

Shooting at ISO 320, F11 and nothing longer than 1/13th, I really didn't expect to get an extended corona.  But after stacking and stretching I got more than I expected.  In fact I am glad I didn't shoot longer than 400mm as the corona in this uncropped shot is nearly filling the vertical space.  That said, 800mm might have been nice for a higher resolution shot of the prominences and inner corona details.  Last thought on this: I've found telescopes to be much sharper than camera lenses even when the lenses cost multiples of the telescopes.  

For processing I stacked similar exposures into groups of 6 and then layered the results using masks to blend them down to the lunar limb.  To get a little more detail I applied a blurred version in subtract mode and blended that back in.  The process was inspired by Sean Walker's tutorial here: https://skyandtelescope.org/astronomy-resources/astrophotography-tips/revealing-totality-in-hdr/   I did not follow it exactly as I wanted something that looked closer to what I saw than the extreme detail version this process can produce.  

I expect next year's long eclipse will be quite different and much more focused on long exposures.
