Partial eclipse viewing: Firecrest 18 Stop Neutral Density Solar Filter from the U.K.
Pro: Nice neutral color. Was in stock at B&H when others were out.
Con: Oh boy. I neglected to try this out on a non-eclipse day and didn’t debug a number of problems, maybe not due to the filter per se.
Cyan colored lens flare. Duh.
Hazy lens flare.
Double image— kind of like what you see if you have cataracts.
Curious: Why is the cyan lens flare image rotated 180 degrees from the main image? Why does the main image of the eclipse look like a banana? [see bottom tip of the crescent]
Upshot: The solar eclipse filter was disappointing.
Update: Photo was very overexposed. I suggest practicing ahead of time by photographing sun spots.
