Comet Pons-Brooks (12P/Pons-Brooks), which returned for the first time in 71 years, recently gradually entered its best observation period. Its current brightness is about magnitude 5. As long as the weather is nice, you can find it after dark at low altitudes in the Northwest where there is no light pollution!
Comet Ponzi-Brooks
Comet Pons-Brooks (12P/Pons-Brooks), like the famous comet Halley (1P/Halley), had records of observations long before it was recognized as a periodic comet. Pons-Brooks was recorded in the Ming Dynasty history book “Ming Shilu” “-The Return of Comet Brooks in 1385. Furthermore, the periods and orbits of the two are also very similar, and they are both bright comets that appear only once Once in a lifetime. Comet Ponzi-Brooks will pass perihelion on April 21 and is expected to reach its maximum brightness of magnitude 4, but it will be too close to the Sun to be easily observed. It is recommended to observe it after sunset, from mid-March in early April, in a dark place, with binoculars and other equipment – you may be able to see its fluffy foliage and even its tail.
It is worth mentioning that on April 8 (2:00 local time on April 9) a rare total solar eclipse will occur in North America: during the total eclipse period of more than 4 minutes, there is a possibility of seeing comets and Comets. during the day. Wonderful sight of other bright stars appearing!
Photography tips
To successfully photograph comets, the method is similar to photographing the Milky Way. The first thing to do is look for an open place without light pollution: in Taiwan the mountains are the first choice, followed by the sea. As for equipment, we recommend using a camera or cell phone capable of long exposures, preferably combined with an ultra-wide or wide-angle lens so you can see the foreground and the comet in the sky. included in the photo. Since a comet is a dynamic object, it is recommended to use a long exposure to capture its trajectory and beautiful tail. However, you should also pay attention to the exposure time, so as not to drag the stars across the sky in star trails. For a super wide angle equivalent to 16mm, it is recommended that the exposure time is within 30 seconds.
When shooting, it is highly recommended to try to stabilize your camera or mobile phone and, if possible, try to use it with a tripod. In general, it is recommended to arrive at the preset shooting location before it gets dark, set up the camera/mobile phone and adjust the composition while there is still natural light, and then wait patiently for the dark comet to appear. If you are not sure where the comet will appear, you can download a starry sky app (such as Stellarium Mobile) in advance: by entering the correct date, time and location, you can know the direction and time it will appear . the comet appears. I wish you all the best in successfully photographing Comet Ponzi-Brooks.
