That is very cool! I want to do stuff like that. What mag was the asteroid? What program / website do you use to ID it etc?

[Astroman (Andrew Wall)]

I only used C2A to identify the Asteroid. I am only assuming at this stage it is it, since I am not 100% sure how to otherwise... As for Mag, not sure, I'd say between 11 and 15...

Okay thanks. I'll try it out.

I got this of Calsky.. although the Emphemeris is out of date a little...

Did you use DSS to do the stacking or how did you make it? I am interested in making one of this

[Astroman (Andrew Wall)]

Yes I used DSS, and saved the registered and calibrated frames, then used a program called infranview to crop and brighten it up a little, so it was more visible. All frames were saved, then, put into Sony Vegas for final video work. I repeated the frames until it reached about 30sec.

Hi Andrew, I am taking some pics of Vesta and hopefully can make something likes yours. May I know more detail how did you make the movie? Say I have some raws then how should I process in dss..etc?

thanks in advance

Hello,

First thing you want to do is Register and Calibrate all your frames in DSS. This way all your images have been calibrated with Darks, Flats, etc... This should remove any unwanted noise, hot and cold pixels from the images and leave you with whats important.

SO with Lights, Darks, Flats etc... checked you are ready to register them, click on Register Checked Pictures... Once you have the screen pop up. Click on Stacking Parameters. Another window will pop up... Click on Intermediate files tab and select Create a Registered/Calibrated file for each light frame. Make sure you have TIF selected. This should save the Calibrated individual images that are fully registered.

Once you have done that and DSS has done it's business you can go into a graphics package and edit the frames as you with, but do this in a batch so all images get exactly the same treatment. Enhancing the object to make it more visible. Then once you are happy with that you can put the frames in order into a video editing package and make your movie as you seem fit.

VirtualDub does a good job at making an animation AVI out of individual frames.

If you get stuck let me know and I will try and help you out.
