Hopefully the sky clears soon for those still clouded out, hopefully you all will get to see it before it fades,,,
The ion tail and Anti-tail have already disappeared, but the nucleus and dust tail remains bright enough to see in Binoculars. But Changing geometry will likely let us see the Ion tail again in the next few days...so keep watching.
How to see it and A Simple way to capture Comet Lulin!
You don't need a telescope to see Comet Lulin, it is barely visible to the eye, but looks great thru Binoculars or any even small department store type telescope.
But you do need to know where to look, it is moving Rapidly and is now approaching Regulus in Leo, here is a link to the sky chart or map at Spaceweather.com
You can capture it with just a regular camera & camera lens, I used a Canon Rebel Xsi Digital SLR + a Canon 75mm to 300mm lens, set to 280mm At F5.6, this is a 16 minute exposure or 4 (4 minute subs).
Don't have a 280mm lens? No worries...
I also captured it with a 50mm, and 70mm lens, it looks great at super wide angle as well.
My shot was captured on Tuesday Night from Yellow Springs, Ohio, shooting in between the high cirrus clouds.
I used a tracking mount, and stacked the 4 separate shots with the 280mm lens.
You can even see some background galaxies to the far right of the comet, 3 are easily visible in this image.
Don't have a tracking Mount?
Try a simple DSLR or SLR camera on a tripod,
Make sure you photograph the Comet away from city lights, this way your image will not fog up due to light pollution.
Set your camera to 30 sec. or Bulb setting or manual Exposure setting, you will need a cable release or a self timer, this helps a lot, so you don't have to touch the camera to start the exposure.
Focus the camera lens on a bright star first, (turn off auto focus mode) set your camera lens to infinity, but sometime Infinity is not perfect focus, so check it out on a bright star to make sure, if not focus it manually until it is sharp.
If using a DSLR, take a test shot to make sure.
Focus is very important. Note: Autofocus will not work properly with night sky shooting, it has a hard time locking in on stars. You must Focus Manually...once you are sure your in focus don't touch the lens any more.
Aim the regular camera & len (any lens 28mm to 50mm set to F5.6 or F4 or lower) at the general area of the comet, be sure to Lock the tripod platform so it does not move during the exposure.
Now take a ten 30 second exposures.
DSLR's Transfer your pictures to the PC,
If using Film, Developed them , then scan your negatives to make them digital,
Now stack the ten pics using free software on the web or Adobe, Nebulosity, Deep sky stacker, etc. Google the software names mentioned to find the software. Align the Images by aligning on the stars in the software, or alternatively you can stack on the comets head for a different view.
This simple Process will give you an equivalent of a 5 minute exposure, this is sufficient to capture Comet Lulin nicely.
Good Luck shooting and please post all your images up here on Universetoday!
