| 説明 | E-620 + 70mm F4 5sec exposure , 2024/10/21 18:17 , Manual mode/Manual Focus/ISO2000 , 16 images are stacked by sequator.C/2024 A3 Comet could not be seen with the naked eye or binoculars in the city, but it was visible with a 5-second exposure. So I decided to continuously release the shutter and process the image later. 5 seconds is the exposure limit at the 70mm focal length. The sequator works like a software equatorial mount, superimposing multiple images. By superimposing the images, the sequator was able to clearly reveal stars and comet tails that had been obscured by noise. |
