I think it is a good solution!

Line of variation in Guide is often useful under many circumstances. You have to take in account the sun displacement (4 RA minutes per day) but it should be easy for the task of planning your asteroids observation.

However I hope Bill will add in the wish list (hoping it is not toooo long) the simplest and definite solution to your question.

Oggetto: Re: [guide-user] view of opposition of asteroids in Guide -

 
For Riccardo Papini and All of the groop

Riccardo! I thank you for your useful Help!

After your advice I have seen that in the dialog Guide: Extras - Asteroid
Options - there is the possibility of activating the function: - line of
variation in days -. maybe this could be the complete solution to add to
your valuable advice! What do you think?

Bye!
