Tail Of NEAT
Hi all,
Though I kept a generous amount of digital real estate to the left of the photo for the tail, it was not very clear.
From the blobby nature of head , can it be that the tail is behind the head on a vertical plane , at this time , I mean not sideways as with other comets ???.

Hi Kochu and all
Saw your wonderful image of Q4 Neat in the album, It's a good shot.
Finally got around to process my batch of Q4 NEAT images. With minor histogram stretching and curve adjustment in PS, the tail can seen extending beyond the 1/3 deg of FOV. Tail definition is not as spectacular as T7 Linear seen last month though. Due to the fast moving nature of this comet, i had to settle on a composite of 2 images.

Would like to try my hands on generating animated gif of this fast moving comet if time allow.

Neat From Dempsey
Hi Matthew,
The shot is amazing. Your talent had succeeded in bringing out the shy tail. It is true that the format is a bit too small for showing the whole size of tail.

Hi Matt.
yes....very nice and in full colour...! All those practice trips to Dempsey and Mersing certainly paid off. I seldom come across comet pics taken in full colour. Is this the true colour of the comet or due to your processing.
and yes, like weixing, I'm interested to see what the raw images look like.
cheers

Hi
For those who have miss or yet to see the comet, the following link leads an animated Comet Q4 Neat making her rounds in Monoceros, captured live on 9 May by 20 still frames.
http://pachome1.pacific.net.sg/~audiowo ... 09_ani.gif
Each frame is taken at a interval of about 90 sec. It show how fast the comet transverse across 10 arcsec in 30min. Image scale were cropped and downsampled to facilitate loading. it might take a while to complete loading as animation is over 1 mb in size.
For Weixing and Rich, who were curious about the raw images; The above clip contains raw subframe images that came straight from the camera. Each image was registered and aligned to create this gif and it is my first attempt in astro animation using gif; A fun but terribly time consuming experience.
Enjoy the clip.

Another greatly taken photo can be found at http://www.ewellobservatory.com/gallery ... .cfm?ID=30 Just look at the details of the comet. Very nice indeed.
