Solar Eclipse 2021 – Surya Grahan 2021 Date, Timings, how to capture the last solar eclipse of 2021

On December 4, a total solar eclipse, the last of the year, will be visible from Antarctica. The southern tip of South America, Africa, Australia and New Zealand may also see partial phases of the eclipse, but they will not be visible from India.

Meanwhile, Ajay Talwar, astrophotographer and vice president of the Delhi Amateur Astronomers Association, in an interview with, shared tips on how to capture a total solar eclipse.

On October 24, 1995, he filmed his first total solar eclipse since Barkakana in Jharkhand and in 2006 he traveled to Turkey to capture it again. On August 21, 2017, he was in Idaho, United States, to take a photo of the total solar eclipse dubbed the “Great American Eclipse.”

Is there an ideal focal length to capture the solar eclipse?

If you want to click on a photo of the Sun with good detail, the focal length of the lens or telescope should be greater than 1000mm. During a total solar eclipse, the action is not on the Sun but around the Sun. The sun is overcast and you can see the sun’s corona or atmosphere which can extend up to two or four solar rays. The question is, where do you actually want to capture the Corona. If you want to capture the innermost Corona, you need a focal length of 1000mm. If you want to gradually capture the outer parts of the Corona, you can go down to 800mm, 500mm or even up to 200mm.

What is the ideal exposure range?

The human eye can see Corona from brightest to darkest. But the camera is not able to capture this whole range of brightness because the dynamic range of the equipment is limited compared to the human eye. So all exposure settings are good for capturing a total solar eclipse.

With less exposure, the inner crown will be properly exposed and if more exposed, the outer or outermost crown will be captured correctly. Astrophotographers use a range of exposures from 1 / 100th of a second depending on their focal length.

The secret to good astrophotography is planning and preparation. What are your planning tips?

I get to the exact spot about three days before the eclipse and do a full rehearsal. For the June 21, 2020 eclipse, my wife and I traveled through Haryana, Punjab, and Rajasthan before finally choosing a small resort in Sirsa as the perfect location to film the annular solar eclipse.

We usually schedule all of our exhibitions in advance. All equipment is controlled by a computer, even our cameras. At which exposures the photo should be taken and at which particular time, down to the second, are all scheduled.

The most important thing is that you should watch this great sight with your eyes and if you are busy photographing you may not be able to experience it. So we automate all our cameras and we immerse ourselves in the view.
