You can use the "more stars" icon (upper left toolbar, between the magnifying glass and the red lightbulb (night vision mode) icon). Click it a few times to get more of the stars. But some USNO-B stars don't even have magnitudes listed, and these won't show with the "more stars" icon. To get _all_ the stars in USNO-B, click "preferences">"catalog and objects parameters", then click the "stars 1" tab, then near the bottom, use the "star magnitude limits" settings.
>From the help file: ----------------------- Star magnitude limits box: Restrict the star visibility to a certain magnitude according to the chart width. Check "Limit" to activate the magnitude limitation to avoid overcrowded chart. The table on the right indicate the magnitude limit for each field of vision range. If you check "Continuous" the magnitude limit is calculated to always show the same number of stars for each field of vision. In this case only the 35°-90° box is active to set the reference magnitude at 90°. --------------------- -John --- DUPRIEZ Christian <[EMAIL PROTECTED]> wrote: > Hello > > Now, the USNO loading is OK after changing the URL line of > extres.ini. > Very thanks for this trouble shooting action ! > > Another question about the visualisation of USNO B : > I have to do a very important zooming to see the faint stars USNO B > on CdC screen (ex : mag 19 to 21). > Is it possible to change the CdC setup and see all stars USNO B with > a "normal" zooming (for example 5 x 5' or little more) ? > > > Regards > > > Christian > > > > > > > > --- In [email protected], "John Mahony" > <[EMAIL PROTECTED]> wrote: > > > > Charlyms, > > > > There are three different sections of the extres.ini file for CDS, > one > > for each of three different catalogs- one for GSC, one for USNO-A, > and > > one for USNO-B.
