I'm not going to get to see the total eclipse; only about 90% from northern NJ.
I have a Nikon D200 and Sigma 70-300mm f1:4 5.6 zoom.
I purchased a white mylar solar filter at
B&H anyway, as I have always been curious about photographing the sun.
Today I tried the filter out for the first time. I mounted the camera on my K&F Concept tripod and used the cable release.
Settings were as follows:
Format: RAW
ISO: 200
Mode: S - shutter priority
Focus: Manual
I first set the shutter speed to 1/125.
Spotting the sun wasn't difficult with the lens zoomed out to 70mm. After centering the sun, I zoomed in to 300mm
With the lens focused, I could clearly see a sunspot.
I took several photos at 1/125 and at 1/160 - the highest shutter speed I could get before the camera's meter read 'Low'.
I was just trying out the filter, so didn't try changing the ISO or going to a faster shutter.
I downloaded the NEF files from the camera to my Windows 11 PC.
The only program I have that can read NEF is the Windows 11 default photo viewer.
On one of the photos, I could see the sunspot as an orange spot.
I also converted the NEF files to psd so I could view them in my old version (7.0) of Photoshop. What I could see was pretty much the same as what I saw with the Windows photo app from the NEF file.
I realize that I need a much longer lens to get any detail of the sun, and that using the type of filter I own I'm not going to see solar flares.
Since I cannot afford a 1200mm lens, I thought perhaps a 2x teleconverter might help.
Also, I read something about using a polarizer.
When I took the photos today, I attached the solar filter to the UV filter that is on the lens.
So I'll try replacing the UV filter with a polarizer, since I already own one.
Do you think buying a 2x1 (or maybe higher) teleconverter would do anything for me, or would it just make the image larger but less sharp.
I suppose that if I could get to a spot in the path of totality, I would rent a longer lens, but it's not looking good for me to get there.
Any thoughts?
Thanks
