You have a fantastic product! The only shortcoming that I see is its catalog limitations, which is easily fixed. Right now if I convert an observing list in AstroPlanner to .skylist format, objects on the list but not in your database just disappear. I suggest that you add more catalogs, say quasars, pulsars, maybe the entire WDS catalog, etc. I've already paid to get all the catalogs you offer. Thanks!

Chris Could it be that objects are disappearing because of naming conventions of objects as opposed to them not being in SkySafari? I'm assuming you're using 6 Pro? It's very rare that I'm looking for an object that doesn't appear in SS6 so I'm curious to see which objects and catalogs you're referencing. I did a quick search for WDS in SS and it returned 10k objects, the maximum for their search. Looks like this entire catalog may very well already be included. I actually thought, and maybe this is wrong, that SS6 Pro had the largest database of any astronomy software out there?

Tfowler It does not have quasars or pulsars, which use a special naming convention. You can try typing in one of them and you'll see that you get no hits. AstroPlanner has a huge database of catalogs, much larger than SkySafari.

Chris SkySafari has previously said they have 700 pulsars and 18,000 quasars. Is that not true? Being a mobile software, I think they generally get down around 18th magnitudes in galaxies and 16.5 in stars. I think they've sometimes added catalogs when people request them, but it usually turns out they're already there.

Tfowler Chris--
Interesting. They don't come up under standard IDs. I'll have to figure out how SkySafari identifies them. If I export a list of pulsars or quasars from AstroPlanner in SkySafari format, they don't show up in Sky Safari. AstroPlanner uses standard IDs, such as 0157+6212, a pulsar in Cassiopeia. The ID is taken from the RA and the Dec of the object. If you type this ID into SkySafari, nothing comes up.

Also check standard quasar names, such as 3C273, the brightest quasar. This also comes up unknown in SkySafari.

Tfowler Yes that works. Must use space between 3C and 273. That's the trick. Without the space it doesn't work. Thanks Chris!
