First Asteroid - Pallas

Recommended Posts

I had a go at capturing an asteroid last week, and I was surprised at how easy it was.  I didn't really understand that at Mag 9, it is fairly bright.

It is moving very slowly (7" per hour), so  imaged it over at least two nights to be sure that I had actually captured it - and then had a third go.  The middle frame has fewer stars because it was cloudy. 

It clouded over as I was setting up, and I tried a shot just for the hell of it.  Presumably the cloud was very thin, but I couldn't see any stars with the naked eye!

This gif is composed of three frames.  Each frame is 6 x 30s stacked subs, binned 2x2.  Guiding was not needed.  My gut feeling is that this would look quite good shot at a much shorter focal length.

Camera: STL6303,

Scope:   Tal200k  (f/l 2010mm)

Mount:  EQ6

Total exposure  9 minutes

Dark calibrated in CCDStack and processed in the Gimp.

Terrific capture and processing, enjoy tracking them.  Also bit eerie thinking could one with earths name on it be out there.

Great first "tracking" asteroid pic. Just one word of warning ... this sort of thing can be quite addictive ...

One of my favourite exercises was imaging Neptune & Triton (with a 4" achro) with a three-day gap, showing the speed of Triton's orbit and the distance travelled by the pair.

I fear that you might be right about the "addictive" part.  I've already looked up Ceres.  It's a bit low from here, but I might have a go with a DSLR in Spain in the not too distant future.  If nothing else, it will be an interesting technical exercise.
