There¡¯s a pull off across the road from Todd¡¯s tavern market. Good wide open sight all the way to the horizon looking west. Its in Spotsylvainia though on rt 630

Good evening, all,
Random question, what is the best place to get unobstructed views of the horizon? ?In Fredericksburg and Stafford, East and west? ?
Particularly to the west tonight for the planet parade. ?
Thanks,
Bruce

Brian,
While photography filters can be used- they do nit have the defined, known light transmission profile used by professionals who may want the data. You can still due photometry however in the ¡° open¡± position. There are people who do this all the time and just specify the filter as ¡° visual¡±, or ¡° no filter¡± . ?
The light curves I generate are from numerous 30-60 second subs. Sometimes I have hundreds of images by morning. I use Maxim DL for constructing the curves. It has a ¡° photometry¡± feature which is very useful. I¡¯m sure there are other programs out there that can do this as well, and I believe there is even one that the AAVSO has that can be used if you have an account with them. I know you can submit data to them without being a member, but I¡¯m not sure if you have access to that photometry program unless you are a member.?
I know you have expressed an interest in learning to use the MSRO/ RAC telescope. Either myself or Pete Laky can help you with training. You could use that telescope for photometry with the UBVRI filters!?

A few questions. The filters that you use for this type of work, can photography filters be used in a similar way to examine curves and magnitudes? What is the software that you use to analyze the incoming data? Are you getting these data points from a video capture, as it seems continuous, or is it the compilation of lots of subs??

Regards,?
