In follow-up to my post yesterday, I have a correction and a few after thoughts: I have been reminded that the Kwiki video time stamp vendor has ceased operations. http://www.pfdsystems.com/sundown.htm . There is a comparable replacement product, but it is expensive. http://www.horita.com/gpsvideo.htm Pooling resources in group observation is preferred. This recommendation relates to leverage the unique ability to the known time of the impact. NASA TV will be broadcasting images from the shepherding satellite and is offered as a channel on some commercial satellite signal vendors. NASA TV can be accessed via a portable TV dish setup. This will allow observers to time when start that video imaging capture and minimize the amount of wasted disk space. This compares to SMART-1 and Deep Impact, where many minutes of video capture needed to be done, because the moment of impact could not be determined precisely. This consideration weighs in favor of group observing and pooling resources to support a common dish setup. Another timing option seen on Deep Impact is to have one local club member monitor NASA TV on a cable channel. Just before the impact, cells phones can be used to alert remote site observers to start their imagers. Because of the recommended high magnification, box mounted DOB observers may wish to consider buddying up with a tracking mount scope owner. Smaller 5 inch Alt Az mount owners may wish to consider switching to equatorial mount mode. With my Meade ETX 125, even with tracking, alt az tracking at very high magnification was okay, but bothersome. Switching the Meade ETX over to equatorial polar alignment mode, allowed for much smoothier and reliable tracking. With this improved tracking, observing at 300x through a 4mm TMB planetary eyepiece was much more relaxed and enjoyable. Clear Skies - Kurt
