deep sky objects without magnitude from Messier of NGC are missing

[Lukas Middendorf]

Hello,

there are quite some deep-sky objects from NGC (like NGC 6914) or even the
Messier catalog (like M 29) that don't seem to have a magnitude.
Do I have an outdated catalog (it should be from trunk or newly downloaded
with "Get Hot New Stuff")?

Since r1031008 these objects are hidden. I have attached a patch that makes
all objects without specified magnitude visible again.

Regards,
Lukas

M29 appeared fine when I last checked on my laptop. IIRC, I put in a
new NGC/IC catalog that had well-defined magnitudes for all Messier /
NGC objects by merging our catalog with SAC. That was before KDE 4.3
was released. I'll re-check anyway.

It was caused by the Steinicke NGC/IC Catalog from "Get Hot New Stuff". When I
delete it from ~/.kde/share/apps/kstars, M29 has a magnitude again (NGC 6914
still does not).
The Uninstall button in "Get Hot New Stuff" does not work.


btw: Shouldn't  the "Updated Daylight Savings Time rules" be removed (or
hidden by some obsoletion mechanism)? It's the same that comes with main
KStars already.

Thanks for pointing that out. I'll try to look into this during the
weekend. I think the best solution would be to fill in the Steinicke
Catalog's missing data with data from SAC. I'll check out the
licensing terms of Steinicke (I think it's simply "free for
non-commercial use", which is permissive enough) and try to do this.

Oh, okay. I'm not clear on this since that was way before I joined
in. Maybe we could obsolete it, as you point out.
