#1
Hello,
When I use the tool Power Data Search it seems that locations and constellations don't work correctly !
See my attach.

Hi,

There is a known problem with the constellation filter. There will be a fix in the next update. It's not clear to me what it is about locations that do not work correctly. Please elaborate.

Hi Greg,

If I test the data power search with location in Chile or France I have the same galaxies for size >10 arc min !

Hello,

The size in arc minutes of a galaxy doesn't depend on the location. The selection of the location is used in conjunction with the date, and applies only to the Exposure Time limit filter immediately below.

From the help: "Knowing the imaging system, it is possible to limit the search results to objects that have an acceptable image scale. Knowing the location and date, it is possible to limit the search results to objects that have acceptably short total exposure times to reach the required SNR."

Hi Outters,

The workaround for the nonfunctional Constellation filter, is to sort the database results on the Constellation column and select the results for the constellation of interest.

You probably figured this out already, but in case you haven't, I hope this helps.

Why would you expect a search based on galaxy size to yield different results for Chile or France? Were you expecting to get a different set of galaxies for northern & southern hemispheres due to the differing altitudes of the objects?

The constellation filter still not fix? I am using 4.0e and when I search for nebulas in Orion I get the full sky.

Because the two products are intimately linked, I am unable to release an update for ST4 Imaging until ST4 Visual is released, which is very close now. There will be an update soon with fixes and upgraded/new features soon.
