We went to the summit of Mauna Kea last night to see if we could image Comet PANSTARRS. The sunset was beautiful but we couldnt visually see the comet. After returning to our hotel, I scrubbed the images I took and found that my very last shot at 300mm captured the faint comet in the fading glow of the Sun.

After trying every day in the past 9 days to spot it, I finally viewed Comet C/2011 L4 (PANSTARRS) today in the eyepiece of my 8 SCT from Singapore where I live. It was quite faint but clearly cometary, with a fuzzy tail extending upwards. I doubt it would have been readily visible through binoculars even today.
The low horizon levels in the tropics are almost always heavily laden with clouds or haze, making viewing this comet very challenging.
The image quality is poor, but I least I managed to image and view it. At last!

I took some more photos of PanSTARRS this evening. With clearer skies and possible brightening of the comet as it approaches the Sun, the comet appeared noticeably brighter today - even visible from suburban skies.

I photographed this tonight, March 9th at 5:52 PM from a roof deck in Upper Manhattan with a Canon Powershot SX260HS digital camera using a 12 second exposure. The comet was not visible to the naked eye, but did show up on this exposure. Mostly clear sky with some thin after-sunset clouds.

PanStarrs at an altitude of 5 degrees was not visible through the early evening haze but was imaged with Canon 20DB using f/2.4 170mm lenses. 25 RAW frames captured at 30fps with 1/80 sec exposures along with flat frames. Light Frames converted to TIF and calibrated with the flat. Calibrated light frames stacked and aligned on comet.

Well here is a shot of Comet PanSTARRS. We climbed up a hill (the kids and I), to get a good western view. It was NOT VISIBLE to the naked eye. I found it in binoculars first, then pointed the camera in the direction and fired off a dozen exposures. Its REALLY faint and washed out in the twilight right now.

Details:
A break in the weather finally allowed the comet to be found after 6 days of trying. I found PANSTARRS through an auxilliary Observatory 4 1/2 inch Zeiss refractor at 6:31 p.m., P.S.T., March 9 (March 10, 2:31 UT), and in 7X50 binoculars 3 minutes later. This image is cropped from a 2.5 sec exp at ISO 1600 with a Canon 200 mm lens at f/5.6 using a Canon D20a. The parabolic envelope of the coma looked very orange.

Details:
After 9 attempts from 9 straight days. Finally I have the clearer version of Comet C/2011 L4 PanSTARRS heading north just a while after the sunset. Very lucky to have a clear horizon to get this shot with a bit of landscape as the background.
