Howdy all; Well, I have become motivated to update the Saguaro Astronomy Club database version 7.2. I will not make wholesale changes, but there are some...
At the risk of sounding selfish, please don't drop the first edition Uranometria map numbers since I still use that atlas heavily in the field. :-) Sky and...
Mark; I have now had several votes to leave in the first version of Uranometria map numbers. Someone has also told me that the second version is not selling...
1. What is "hour angle" in the position information of stars? 2. How can I tell in SkyMapPro if a planet is retrograde? Is this information given somewhere or...
Chris; If you can tell me which objects, I will certainly change the objects that are at incorrect positions. I have Brent Archinal's book on Star Clusters, I...
Hi Steve, I don't have the original SAC 7.2 catalog at hand (my copy is very heavily edited), but as I recollect, one of the "3C" quasars in it (might be 3C...
Another new user question: I was looking at a partial Solar eclipse in SMP which was visible form my location. SMP shows the moon partially overlapping the...
Chris; Thanks for the list, I will look those over. It seems that the source I used for NON NGC star clusters did have some errors. But, once I am done using...
... That is because, on wide area maps, the Sun and Moon are shown larger than their actual size. When you zoom in and the Sun and Moon start getting larger on...

Hi, In case you hadn't heard, there is a report circulating of a meteor impact of large proportions in northern Norway...Hiroshima-sized energy release. Very...
Is there anyway of displaying the current PA of up of a map? Maybe it would be a useful addition to the map status? Also being able to directly enter a PA...
Hi Mark, Unless you have rotated it, the PA of "up" on an ra/dec map is always 90 degrees - ie north is at the top (unless the map includes the celestial pole,...
Chris Yep, I was of course referring to rotated maps. With wide field maps I assume the PA will change across the map due to the projection? But being able to...
... Thanks Chris, just another item on the to-do list for you (groan!), I had already been using the PA status bar item and clicking to places on the map, so...
Chris, just for your info... I received you original message at 09:47 UTC and the duplicate at 12:53 UTC. In a message dated 12-Jun-06 5:53:28 P.M. Central...
... Thanks Alan - that is indeed the time that I sent them, but they still hadn't appeared on the mailing list web site at the time I switched my computer off...
Yes, I know. We've had the same problems on other groups. Sometimes you think the group just fell off the face of the earth for a while... In a message...
Are the position of stars precessed? I was checking the vernal equinox dates backward and forward. in 2000AD it is 20 March in 3000AD, 4000AD it is 20 March ...
... SkyMap uses the full precision IAU formulae for precession. The reason the date of the equinox changes as you go back in time is because before 1582 (or...
Hi, I was wondering if you could help me. Is it possible to find with SkyMap Lite the moment that the sun or a star crosses the horizon without any corrections...
