Comet PANSTARRS (C/2011 L4) remained a great target for astroimagers nearly three months after its perihelion date of March 10, 2013. This image shows both that both the wide dust tail and the straighter, much longer, ion tail are both active. Expert imager Damian Peach used a 4-inch Takahashi FSQ-106 refractor and SBIG STL-11000M CCD camera to capture this photo. He too an LRGB image with four 3-minute luminance exposures stacked with one 2-minute exposure through the R, G, and B filters, on June 6, 2013, at 5h49m UT.
Comet PANSTARRS (C/2011 L4) is still putting on a show. Unfortunately, at the time this imager captured it, the comet glowed at magnitude 9.3, much too faint to spot with the naked eye. Comet PANSTARRS is heading toward the solar system’s outer reaches. On the date of this image, it was 1.81 astronomical units from the Sun. An astronomical unit is the distance between Earth and the Sun, about 93 million miles (150 million kilometers). Bernhard Hubl took captured image using a 12-inch Newtonian reflector and an SBIG ST-2000XM CCD camera. He took an LRGB image with exposures of 20, 18, 18, and 18 minutes, respectively, on May 28, 2013, between 20h55m UT and 22h30m UT, from Nussbach, Austria.

Noted astro-sketcher Jeremy Perez of Flagstaff, Arizona, made an observation and drawing of Comet PANSTARRS on March 19 while he was out of town visiting family in Elk City, Oklahoma. He reported, "Despite Elk City having lower altitude than Flagstaff and more moisture in the air, the comet was in great form and showing off lots of structure in its tail. I noted three brighter plumes in the main curving section of the tail. There was also a faint straighter edge along the north edge. Along the southern edge, a fainter curving edge peeled away at a broad angle, and then further down, another short, straight segment emanated from the coma. It stretched about 1.5ÒÀ across the width of the binocular field. What a beauty!"
Astroimager Miguel Claro from Corroios sent in the following report: "After a few days of rain and clouds near the horizon, I was finally able toÒšphotograph Comet PANSTARRS in the Portuguese sky. Actually, I had just returnedÒšfrom a weekend photo trip and was exhausted, but the sky wasÒštotally clear, so I found some 'extra forces' to delay my sleep. I took the image in the city of Almada, near Lisbon, Portugal." Claro used a Canon 50D DSLR with a lens set to 108mm and f/5. He set his camera at ISO 1000 and took a 1/60-second exposure March 17 at 7:43 p.m. local time.

Longtime Astronomy magazine contributor John Chumack from Dayton, Ohio, sent in this great story about observing Comet PANSTARRS: On March 12, I drove about two hours to Indianapolis to catch a plane ride with one of my former University of Dayton engineering students, Kevin, who is now a pilot.ÒšKevinÒštook me up in his plane, in hopes of getting above the clouds to see Comet PANSTARRS ò?? or at least fly to an airport farther south with clear weather.
Unfortunately, a really bad storm was brewing to the west over Illinois, and gusty winds blew us around a bit. After a short ride, we landed and decided to we would have to wait for another day to see the comet. We put the plane in the hangar and headed out to eat dinner.
By now itò??s snowing like mad. After dinner, we headed on to Kevinò??s house. As we pulled in front of his house, we noticed the snow stopping, then a huge sucker hole to the west with the thin crescent Moon and Comet PANSTARRS visible. So I managed to pop off several quick shots. For this one, I used a Canon Rebel XSiÒšDSLR with a lens set to 135mm and f/4.5. I set the camera to ISO 400 and took a 0.8-second shot.
Goes to show, that sometimes itò??s worth traveling to increase your chances of witnessing something astronomical, even if your original plan does not work out.ÒšIò??m so glad I went to Indy. In the end, all we really had to do was to wait in front of Kevinò??s house for an opening.
Astronomy magazine image contributor Babak Tafreshi captured thisÒšdelicate shot of Comet PANSTARRS on March 12. He said, "We had some clouds at the horizon this evening from the observatory on La Palma, and it was quite challenging to find the comet and the very thinÒšnew moon (distorted at the horizon), so I'm happy with this lucky result. It was amazing that at that moment I had a passing astronomerÒšcar below the William Herschel Telescope which softlyÒšilluminated the dome!"

World-famous astroimager Adam Block captured Comet PANSTARRS from Tucson, Arizona, on March 10. He said, "Here is perhaps one of the first views of Comet PANSTARRS from Tucson. This might be a typical view from a city and this image is similar to what it looks like through binoculars. Look for the comet 30 minutes (exactly!) after sunset as it gets a little higher above the horizon each night this week. You will only have about 15 minutes to find and enjoy it before it sets. Needless to say, it is a challenge.ÒšThe comet will be shown each night from the Mount Lemmon SkyCenter as part of our public shows. The SkyCenter will also publish images of it this week as it becomes more easily seen in the twilight (check our website for updates!)." To get this shot, Block took a 4-second exposure through a Canon EOS 40D DSLR with a Canon EF300mm f/4L IS USM lens set at f/13.
