I have never seen a photo of a moose laughing! A great photo. And I hate to say it, the moose does appear to be laughing at you. It must be you!

I bought a solar filter for the eclipse. Now I am wondering what other events I could use this filter-
Bill Seng


I know that the others have suggested sun photography and welding photography, but I suggest more eclipse photography. There are some others to go to. On August 12, 2026, there is Iceland and Spain. On August 2, 2027, there is Spain, Morocco, and Egypt. On July 22, 2028, there is Australia and New Zealand. And then we go into the 2030's.

Maybe. But if the energy from the light were to focus on any of the elements for any amount of time, and it damaged any of the elements, that would trash the lens. I don’t want to take that risk. (Very expensive lens. $14k)

Since we don’t have another total eclipse for another 20 years, I have time to make a solar filter to cover the front element of the lens. Will do using this. 8"x8" Solar Filter Sheet for Telescopes, Binoculars and Cameras

No eclipses in the US until 2044 (the tail end of one at the US/Canadian border) and 2045. But there are a bunch to go to in other continents and countries. There are at least three nice ones before 2030.

I shot the eclipse. Would have preferred to use my 400 f/2.8 but I did not have a large enough filter to cover the front element. I used my 100-400 because I had a 77mm solar filter.

My question is, my 400mm uses a 46mm drop in filter just in front of the camera, not in front of the front element, will the sun damage the elements and coatings in front of the filter? I did not want to take the chance of damaging my lens, so I did not use it. I have ordered some sheet filters large enough to cover the front element in the future.

Thank you for answers.

Here are a few I was able to get.

The main problem with a drop-in filter is getting it out fast enough for totality. There is a chance depending on where the aperture iris is for possible damage to it and depending on how strong the light is concentrated on the filter itself (overheating, cracking), but they usually are located far enough away from the most concentrated light and tend to be sturdy enough. But there is a chance for damage depending on their locations in the lens. Obviously, killing the light levels before any of the lens elements start concentrating the light is the best way to go.

Western New York had beautiful clear skies April 6,7, and 9. April 8 was socked in from Buffalo to Rochester and beyond going east. So many had travelled here, and so many here had such high hopes for great eclipse photos. My son put out huge expense renting equipment and even an airplane so he could get great photos. All we got was dark clouds.


Do not get discouraged. I have traveled to three eclipses. One was A- rated, B+ rated, and one total clouded out one minute before totality. And the clouded out one was over 6 minutes long and from other unclouded places showed prominences. C'est la vie. Just go for the next one.

I am wondering if anyone can explain what happened with my photos of the 2024 eclipse. Here's the setup.

I was near the center of the path of totality. There were a few high, very thin clouds, but the view was pretty much clear and unobstructed for the entire time.

These pictures were taken with a Nikon D5500 with Nikon 18-55mm zoon, set to 55mm.
Focus set to infinity.
Solar filter was installed.
Exposure was manual (I think F8, 1/30 sec, ISO 800).
Pix taken every 1 minute via remote shutter release.

I also had a Nikon D5100 with a Sigma 600mm reflector lens. Same exposure settings. Solar filter installed. Pix taken every 1 minute using an intervalometer.

The D5100/600mm took decent (although overexposed!) photos. You can plainly see the eclipse progression from beginning to end of the partial.

The D5500 only took pictures of a round image - no eclipse change noted, other than position. Just a round dot.
I know that the setup should have worked because I could see a difference when I moved my hand in front of the lens (using LiveView).

I've also checked the D5500 since then to see if there was any kind of damage to the sensor - everything looks fine.

I would like to understand what happened to cause every image to be the same dot.

This appears to be a focus problem as some of the others have mentioned. Many cameras cannot autofocus on the sun, moon, and stars without having firmware that handles it. The best way to take solar exposures is to practice before an eclipse by taking just photos of the sun. This helps to iron out many of the problems that one faces during an eclipse. Although the next US eclipse is the end of an eclipse at the Montana/Canadian border in 2044 and the California to Colorado to Florida one in 2045, there are other ones to go to. Iceland and Spain in 2026. Spain, Morocco, Egypt in 2027. And Australia and New Zealand in 2028. And there are a number of them in the 2030s including ones in Australia, Japan, and New Zealand. Practice on the sun and go to one of these. There are all worthwhile trying for.

We had both high and low clouds for today's eclipse, fortunately just before totality the low clouds drifted on leaving a good view of the eclipse. I had to shoot handheld resulting in many poor photos. My first pass revealed this shot just as the final diamond ring appeared with the bonus of several flares (hope that's the correct term). May find others when I can give all shots a good review.


You did a great job of getting a difficult shot beautifully! As far as the term flares, flares is correct along with the term prominence. They are interchangeable - but flares is easier to spell, pronounce, and understand.

Hello all,

I'm off to Iceland in a few weeks. I was wondering from anyone who has gone in the past, what focal length they found most useful. I realize much has to do with your subject matter and style of photography, but in your opinion what's the widest and longest focal length actually needed for mostly landscapes. Let's not worry about puffins and whale watching, since I realize that's longer focal lengths, but I'm speaking mostly for landscapes.

I know I'm taking a 24-120. I'm likely taking a 20mm prime. I'd deciding between a 50mm prime or a 70-300.
I'm not sure I have room in the bag for both. I'm taking 2 camera bodies as well. I'm trying to keep the weight down somewhat.

thanks
Mike

I would consider taking the 24-120 on the body of most preference and the 70-300 on the other body. Based off of bhapke's info, I suspect you will use the 24-120 about 90% of the time. If you have the room and don't mind the weight, take the 20 also. But I would suspect you will not use it much.

Sad to say, you are correct.

It’s a difficult thing to try and get your camera dialed in for the eclipse.

In doing so, don’t burn out your retna! Or your camera chip! I did testing today. With filter, on manual, at 1/1000th at f/8, I got great exposure. In Clevland.

I used bracketing, 5 shots, at 1/3rd increments.

At totality, remove your filter and go for it.


You are in one of the few possible cloud free areas. I wish you all the luck with your shooting. Out of the three I have gone to, two were an A- and a B+. The third one was clouded out one minute before totality. If you get some good chromesphere shots, be sure to put them up. Some of the other things to look for, the shadow coming towards you, the darkening of the horizon, the narrow strip of yellow/orange atmosphere on the horizon, the darkening of the sky such that the stars and planets come out (download a map of where the planets and stars will be), feel the temperature drop (especially at totality), and look for possible sunbands (shadow bands, similar to waves, on the ground). If there are animals, watch their behaviors as totality approaches. Photos to try for are Bailey's Beads (coming and going), diamond ring (coming and going), and bracketed exposures of the chromesphere. And don't forget to just take a moment from everything going on around you and look at the eclipse. Most of us that see one want to see as many more as we can. Eclipses can be addictive. And usually anything short of seeing another total eclipse is just a "ho-hum" partial eclipse. That is why I am going to check NASA's site for where the next ones are. Again, good luck tomorrow.

There wont be any chromospere here at ~43N/74W. I have no interest in recording a partial eclipse as theres no aesthetc quality to those. Its just an orange disc and a black disc playing tag. A child could easily draw exactly that same image in Corel Draw.

I was merely curious as to how scrap plastic stacked up compared to the "official" filters. Verdict: Due to haze, I cant speak to possible slight loss of sharpness from an 1/8" piece of plastic but otherwise no hey problemo. If you ever saw pix of any partial eclipses you have seen that perfect sharpness actually doesnt matter anywho.

I know theres paranoia about unsanctioned filters. Acoarst there was no risk to my eyes and Ive attached a test frame showing that the sensor is unharmed.

I will be watching this one on TV. I am just packing camera equipment (smaller camera case; one body and two lenses) and getting ready to go to my granddaughter's wedding. There will be more for me to see. Just none in the USA until 2045. And like you said, after one's first total eclipse, anything short of another total eclipse on the centerline is not that exciting.

Most folks are simply not paying attention to the solid month or warnings.
Be careful, be safe


Unfortunately, there will be people with damaged eyesight. People think of the sun as an everyday thing that causes sunburn with long enough exposure. Then they try "viewing" the concentrated sunlight of a DSLR telephoto lens. Usually instant burning and blinding of one's eye. There will be an unfortunate number of them tomorrow.

I know nothing about the properties of black plexiglass -- all I am saying is be really sure you are correct.

Welders glass is acceptable for visual viewing of the partial phases of the eclipse. Welding produces copious amounts of intensity light and UV rays. I have used welders glass for welding, solar viewing, and solar photography. It is safe as long as you use welders glass that is 16 to 19 stops. 16 stops is too bright and 19 stops is too dark in my opinion. I have used 18 stop welders glass for three eclipses with no problems.

Today Sunday the sun was partially eclipsed by various trees. Also the sky was slightly hazy and I was curious what effect that has.

My solar filter is a piece of black plexiglass, such as can be harvested from discarded consumer electronics.

Pix attached.


Looks like it did OK. It should be good enough for partial shots. Post some of your chromesphere shots if you take any.

No; it just means you wipeout your camera, not your eyes. Do you remember when you were little and used a magnifier to burn sticks, leaves, and ants? A DSLR is just a bigger and just as dangerous magnifier. It will burn eyes.
