Hi,

Is it possible to do batch photometry on an asteroid that is moving over the star field in the image sequence?

Hi,
this feature is included in Service Pack 3, which will be released in 1-2 weeks.
(At the moment it's not possible).
Fabio.

Thanks Fabio. Looking forward to that.

Fabio, is the "Follow minor planet" Motion Angle true angle, degrees east of north or the angle in the image?

Is there a step-by-step guide somewhere?
I am struggeling to make it work.

Hello, it's the angle given by the MPC.

In the mask below select a hourly query (1) , if the object is a NEO you may need to select your earth location (2)
Click "Get Ephemeris", then in the query result select a UT near your exposure (22:00 in the example). The angle is the item (2) which is 241.4, the speed is the item (1).

P.S. if you have an updated MPCOrb file, both data can be calculated by AA with the "Find" button in "Follow minor planet"

Thanks Fabio, that helped.
