Asteroid 2004 BL86- imaging help?

[harrythemartian]

Hi all, wondering if anyone can help me here.

so, i was out on the 26th/27th trying to image the asteroid, and I'm having trouble spotting if i captured it or not.

I had a 50mm lens on a static tripod, and i took about 40 or 50 images each a minute apart. I was hoping to be able to flick though the images afterwards and look for a little moving speck.

However, because i wasnt tracking, the whole star field moves between each frame, making spotting the asteroid difficult.

Can anyone recommend any software (or any existing functions in registax, deep sky stacker, GIMP etc) that will let me align the star fields, either into a single image or a set of nicely lined up ones?

many thanks,

Harry

How long was each exposure?

I used a 55mm lens and the asteroid at 15 seconds gave a long thin enough even shaped object that I could find it on each sub.

they were less than that, about 4 or 5 seconds. i didnt want the stars to trail.

i guess i could look through the subs for a line, unless it would be too short with those exposures

It might well be too short. But if you know the time you took it and were pointing in the right place should be able to work out roughly where to start to see if you did pick it up for the expected path it was taking then.

yeah im pretty sure i was pointing in the right place. it would just be really easy if i had a way of flicking through the images

Could make a timelapse I used Quicktime Pro which I already had.
