Solar Imaging

Recommended Posts

I get the same results from my Sony A7III and Sony Lenses as I did with Nikon and Nikon lenses. I think the problem is atmospheric. I live in a valley. At night, I cannot see any stars because there is alway a fog overhead. It seems that the fog is here even during the daytime. Below is a photo of the sun using the Thousand Oaks solar filter.

Has anyone gotten any better and from what location?

That is only one of many images. I tried various exposures. All have that ring around them. Others in my area confirmed the cloudy/misty skies. A few hours after this posting, the sky became very dark. The sun couldn't even be seen.

It might already be so. I searched for photos from this area and never saw the clear sky that created such hard shadows in my images as I've gotten in the north of the USA. In some parts of Germany the sky is also rarely pure blue, caused by fog (f.e. valley of the Danube) ond/or dense air traffic.

Living in a valley implies, you are surrounded by mountains. Have you ever tried to climb one of those mountains and shoot from there?   Note my tagline  ;-)

Sure I considered it. But, I don't have the energy any longer to climb. I'm still dealing with the after affects of Lyme disease.

I regret to hear that.

But, provided you can still drive around, or have someone who can take you somewhere, it's always worthwile to get to a position as high up as possible for any kind of celestial observations. Because the lowest parts of the atmosphere tend to be the "thickest", haziest, foggiest and most polluted. It gets better the higher you go. For night sky views (stars) and/or shots it's advisable to select a place as far away from any artificial light source, like human dwellings.

Good luck with your recovery.
