Hi,

I got the errors with my ASI1600 again after using a cheap USB3 extension cable. With the original cable, directly connected to the PC's USB3 port, everything is running without errors.

fehlfarbe created a new topic ' Hide objects on zoom' in the forum. 4 years ago

Hi,

KStars can hide objects and allsky overlays when I move my view. Is it possible to activate this feature for zoom too? The DSS colored allsky overlay (very cool feature btw) is activated on my computer which makes the zoom very laggy (even on my notebooks i7 cpu) and I zoom too far in/out. There are no problems if I deactivate the overlay.

fehlfarbe created a new topic ' Comets in KStars' in the forum. 4 years ago

Hi,

some weeks ago I was looking for C/2016 R2 (PANSTARRS) in KStars but I couldn't it. So I checked the comets.dat and it seems there are only ~443 comets in the list which are all periodical. So I looked up the JPL query and there is a filter on ksutils.cpp:1253

QByteArray query("obj_group=all&obj_kind=" + kind + "&obj_numbered=num&OBJ_field=0&ORB_field=0");

obj_numbered is set to "num" which means there are only official named comets selected:

And finally, the numbered state can be "numbered" (meaning the object has been officially numbered by the IAU) or "unnumbered"
( ssd.jpl.nasa.gov/?help_sbdb_query )


I just changed obj_numbered is to "all", recompiled and got about ~3500 comets. There should be an option (checkbox?) to add non-periodic comets to the list.
