After a few cloudy nights on the trot, I finally had a nice clear night to capture this spectacular comet.

The first image was taken last, with a 50mm lens and shows about 18 deg of tail.

Nicely done Joe. :thumbsup:

Weather around the Sydney region has been rubbish....hence no joy
from my neck of the woods.

Thanks Peter and Derek,

My previous attempt was last Saturday night and I had to drive 70km west to escape cloud. Clouds on Sun, Mon, Tue. Frustrating, two of those nights saw an almost completely clear sky with just a line of blocking cloud along the western horizon. Unusual weather for me, I normally get between 2 out of 3 to 3 out of 4 of my nights clear at this time of year.

cheers

Great comet images Joe. Ditto what Mr Ward said about the coastal weather.

Hi Jeff,

Sorry about that. Unfortunately, warmer ocean temperatures off SE Australia related to global warming are producing much more atmospheric water vapour and this inevitably produces more coastal cloud especially at night when moist air from the ocean meets cooler air over the land.

Very well executed indeed.
Reminds me of Comet McNaught..
Say what are those other three or four type tails @ 1:30 - 2:00 & 2:30 as the clock face from the nucleus.
Are they an ion tail plus other forms ? ?
Super interesting and great work Joe !

Hi Bob,

Thanks for your kind comments.

My understanding is that they are other dust tails ejected during the sungrazing perihelion. I believe their formation is due to drag caused by something called the Poynting - Robertson effect.

You can see the formation of those extra tails in this photo taken near perihelion:-

I have seen them appearing in other photographers images from last night.

kind regards

Joe
