Oh for crying out loud, THERE ARE NO FRAGMENTS showing in my image. The two main culprits, showing white, are stars. Two others are artefacts, tufts of coloured noise showing in only one sub. Their faint reddish colour in the stack is a dead giveaway when you see it in RGB DSLR shots. I sorted all this out yesterday morning first thing although I didn't bother identifying the star designations because I knew they were stars, not part of the comet. Please see attached image:

That's all you had to post in the first place, Rob, to clear it up. If they're stars, then that's what they are. I said as much in an earlier post. No need to get upset about it!!!.

I wasn't interested in the rest of the objects you identified there....I had no qualms about what they were, just those near the head in that line.

In any case, I've politely asked Terry could he rustle up another comet for us, around June/July, but something a bit larger so it puts on a really, really awesome display and then we won't mistake any "problems" with the nucleus

Comet Lovejoy on Christmas Day 2011

Photographed from Kiama, NSW. This was the best I've seen it, and I've had nothing but overcast skies since then.

In the last photo, below, you can see Kiama Lighthouse on the left, comet Lovejoy on the right, in the rapidly brightening morning sky. What a show!

lovejoy from the gippsland lakes

here are some images i captured yesterday morning from the gippsland lakes where i'm supposed to be concentrating on being camp director.. 30 kids arrive tomorrow!

bright green airglow visible in first image (just 30 seconds). seems much less obvious in the longer exposure (5 mins). captured the extent of the tail other people were referring to as well.

was much fainter this morning and only got a few shots through some short gaps and haven't processed any.

have setup gear tonight and hope it will catch the comet without me having to get up!

cheers
Phil

Great shots Phil. I've been waiting for you to post some more! It sure does stand out nicely in the long exposures. I had the same green airglow the last couple of nights too.

"have setup gear tonight and hope it will catch the comet without me having to get up!" - you lazy bugger! Stay up and tend to your equipment like the rest of have to! haha. Half your luck... although there's something wondrous just standing there staring at the comet rather than your eyelids! I don't have 30 kids to look after though...

And great shots Rudi - love the way you framed them with the trees.

Photos from the 27th

Here are some more 'arty' shots from the morning of the 27th that I posted in another thread. I noticed that there was a green glow on the horizon showing up in the first hour or so of photos that I took, which is probably airglow. Later images didn't show it at all. All processed in PS5. #2 was processed from RAW file while others were jpg.

#1 ISO 6400, 30 sec, f4 at 12mm
#2 ISO 6400, 30 sec, f4 at 22mm
#3 ISO 6400, 30 sec, f4 at 12mm
#4 ISO 3200, 30 sec, f4 at 12mm
#5 ISO 3200, 30 sec, f4 at 12mm
#6 is a stack of 6 images to show the full ISS transit, ISO 3200, 30 sec, f4 at 12mm.

Is the time for viewing still

Is the time for viewing still 3am SA time ?

As it looks like we might finally have a clear sky

If you have a clear unobstructed horizon below the pointers you'll see it right now! If you don't, then wait for it to rise a little at about 3am...

The tail is about 26 degrees long this morning. It is hard to tell where it ends because the tail ends in front of the milky way.
It is easy to see the tail to the right of alpha Cen, and the tail can be seen to the tight of beta Cen, but that is not easy. The comet is fading.
I observed with 7x50 binoculars, moving them back and forth across the tail.

Photos from the 28th

This set may be the last photos I'll take as I need some normal night-time sleep now! And I've probably taken enough shots at this location!
I have a time lapse from this set that I'll post when I work out how..

#5 shows the ISS passing in a 30 sec exposure
#6 is a stack of 7 images to produce the complete ISS transit
#7 A stack of 100 30sec images. Although the comet can't be seen, it is there! The time lapse I will post is based on an extended set of images from this set.

There is so much in crap data. (blue halos on stars)

This is set 1 of 2 this morning with the Pentax DSLR tracked.
A stack, then a Keller curve, then extract luminance..and a star tweak.
Negative shows the extent of the tail.

Seeing was better this morning in Adelaide, transparency was better.
It shows, comparing this morning's to yesterday's.
Glen C is dead right, the tail does extend past Beta Cent!
They must be good binocs, and well trained eyes Glen

Edit: added set 2. 03:31am-04:31am local

If you squint at the first colour shot until only Alpha and Beta Cent are
visible, that's about what the comet looked like from suburban Adelaide.

And finally, set 3, the last set which includes twilight and
the comet head finally showing above the house.
That TV antenna HAS to go

Beaut images guys, really well done..

I went out last night but for some reason my camera decided not to play nicely, I didn't realise this until I had downloaded the images onto the computer, sigh...

here is a rough stack of 42 images each 1 minute long. Stacked in DSS. Artefacts were caused by the field rotation during the course of the exposures. Comet is still showing a nice little central bar. Something that was visible naked eye from where I was shooting from. This will be my last night out with the comet so I am happy with what I have got so far.

Oh and here is another image of me watching the comet...

Nice shots, Andrew

Actually, I think that first shot looks quite effective. Looks like that "pencil drawing" effect you can get in many image software packages

The second shot isn't quite right...you need to be doing something wacky in the shot to make it look good

I don't agree, the shot speaks volumes for me.
Great work Andrew
