Eric, it's a matter of personal choice and preference. I have Sky Safari on my smart phone and TheSky on my laptop, but I don't use them in the field. I don't like exposing my laptop to desert conditions, and Safari on the phone is still awful bright (even in night mode), especially when you have to "wake up" the screen and get that momentary flash of white-light graphics. I like charts because I can write on them and make notes about a particular star in the field, or an unidentified galaxy I picked up, and so on. But I don't think either side has a clear advantage over the other. There is more even in the basic editions of Sky Safari and TheSky than any human has time to observe.

It also has 15,000,000 stars, 740,000 galaxies, etc. What am I missing vis-à-vis the advantages of printed charts?

They are in pdf format and can be printed to use at the telescope. That said one can print a chart and mark it for desired objects and write notes on the back. Then another chart of the same page can be printed for a different project Ken Sikes http://www.geocities.jp/toshimi_taki/atlas_85/atlas_85.htm -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
