Lovely movie Murray!

Nice smooth animation, what program did you use to make it?

Cheers,

Justin.

I used Nebulosity to calibrate and stretch the individual frames. I then saved them in the JPG format. The movie was made using VirtualDub and the Xvid codec. I selected 10 frames per second which is a bit jerky but I only had 78 frames to play with. Thanks.

Hi Murray
I love the star trails in your image - the comet has come out soooooooo well!
This is one of my favourites to date!

Beautiful image. Turned out really well. Enjoyed the movie also. How was the comet tracked?

Andrew, I didn’t track the Comet. I used PhD guide to track a field star as per normal. I let the comet drift across the frame during the night whilst I slept. I then used Nebulosity to align all of the frames on the Comet nucleus. This meant I had to crop the final image. Ditto for the individual frames to make the movie.
