I am member of the International Occultation Timing Association (IOTA). We regularly observe asteroid occultations using a technique we refer to as "pre-pointing". With pre-pointing, we point the telescope to the point in the sky where a star will pass over at a specified LATER time during which the star will be occulted by an asteroid. Many years ago, Bill Gray added a "star trail" feature to his program, Guide, which allows us to generate charts showing where and when we should point the scope in advance to see a specific star pass over the "target location" at the specific time of the occultation. I already use SkySafari in the field for occultations and It would be very handy to have the star trails in the field using SkySafari (so I don't have to go back/forth with printed charts from Guide). Please contact me if this is a possibility and you would like more details/input on the useage of this feature. Thank you for your consideration of this request.
For further information, here is a link to a powerpoint presentation describing how we use pre-pointing:
