Guys i need your help i have a problem with my gcam cstark v4.2 .i can t view photos after taking them so i always have to take a photo and exit the gcam then open the stock gallery to view the photo It actually started happening today even without me doing any changes Note : i have already reinstalled and restarted the phone& all that didn t help

  • News
  • Screen Shots and Software Documentation
  • HowTo setup the RaspberryPi and NUC
  • Zwo-Server Newsv0.355 (2023-12-21)
  • Use the (dimenionless) ratios 'dx' and 'dy' as a criterion whether to send a correction to the telescope and guider probes. Require [abs(dx) .gt. 0.1] AND [abs(dy) .gt. 0.05]
  • Plot 'dx' and 'dy' on the 'tc' and 'fw' plots (temporary feature).
  • The '-mp' (PFS) mode automatically applies the switch '-o -10,85' Download zwogcam-0355.tar.gz v0.354 (2023-12-20)
  • Added a second (optional) parameter for the "gm" command. That parameter may be 't' or 'p' and is only relevant in 'gm3' mode.
  • In 'gm3' mode, limit sending corrections and graph updates to once every 5 seconds or every 'av+1' frames, whatever is longer. Download zwogcam-0354.tar.gz v0.353 (2023-12-19)
  • Use the parity parameter when calculating telescope offsets (flip X: dx=-dx). Download zwogcam-0353.tar.gz v0.352 (2023-12-18)
  • Fixed a bug in the east calculation for the (Az,El) "L".
  • Added the partity parameter for the compass "L". It may be set using the '-i' switch, but is imlicitly set to '-1' in the '-mp' (PFS) mode. The '-mp' (PFS) mode automatically sets these switches: -a -128 -e -1 -r 0 -i -1 Download zwogcam-0352.tar.gz v0.350 (2023-12-17)
  • Added a new switch '-o' to adjust the center of the window on the array: -o dx,dy: adds dx,dy pixels to the center coordinates. In a future version I plan to add the proper offset (TBD) when using the PFS slitview mode (-mp).
  • Added an experimental guider mode (gm3) for use with a slitviewer. It creates 4 sums: pixels above, below, left or right of the cross hair. Then it sends a corrections to the TCS of 0.1" multiplied by the 'sn' (sensitivity) parameter (defaults to 0.5); ie. a 0.05" correction. Download zwogcam-0350.tar.gz v0.347 (2023-12-08)
  • The EDS-801 message is sent every 'av' frames or 1 second, but never faster than 'tf'.
  • Send EDS-82i messages (format: 82%d; %.1f %.1f ). All cursors are sent at startup; thereafter only when a cursor position changes. Please note the spaces before and after the cursor coordinates. Download zwogcam-0347.tar.gz v0.345 (2023-11-21)
  • PFS mode: the switch '-mp' uses a smaller FOV (1200x1200). This required a change to the mask filename convention to include the geometry: Rename the existing mask(s), eg. "zwoSERIALNUMBER.mask" to "zwoSERIALNUMBER_1800.mask". Then you will need to create a new bad pixel mask when in PFS mode that will be named "zwoSERIALNUMBER_1200.mask". Download zwogcam-0345.tar.gz v0.344 (2023-10-31)
  • Send guider corrections (and EDS 801 messages) only every 'av' frame.
  • Keep open EDS connection during guiding (do not close the socket after each message). v0.343 (2023-09-13)
  • Layout change: Move the "av" box next to "tf".
  • Re-use the exposure time countdown box to display the send countdown.
  • Re-use the frameCounter box to display the last frame number sent. v0.342 (2023-09-06)
  • Append '\n' [LF] to the EDS messages (was '\r' [CR]).
  • Report the error message "connection to TCS failed" when "F9/F10" fails to connect to the TCS. v0.341 (2023-09-01)
  • Reduced the wait for an EDS response from 2 seconds to 50 milli-seconds.
  • Updated the format of the 801 EDS message (moved the guider-flag to touch the FWHM).
  • Close connection (hangup) between messages. [v0341b]
  • Append '\r' [CR] to the messages. [v0341c]
  • Bug-fix. [v0341d]v0.340 (2023-09-01)
  • Wait for a response from the EDS. v0.339 (2023-08-31)
  • Terminate the string sent to the EDS with a '\0' byte (was '\r'). v0.338 (2023-08-31)
  • Do not wait for a response from the EDS. v0.337 (2023-08-25)
  • Made the FWHM sanity check less restrictive. It interfered with measuring the very small pinholes. v0.336 (2023-08-18)
  • Added the '801' EDS message to the TCSIS.
  • Most keyboard commands should work over the TCP/IP interface. v0.332 (2023-08-01)
  • Renamed various instances of 'zwoguider' to 'zwogcam'
  • Added a basic TCP/IP interface. Currently there are only three commands, "version", "fone" and "fthr". v0.331 (2023-07-28)
  • Swapped F9/F10 functionality.
  • Set 'send=0' when using 'F3' for the first time in 'fm2' mode.
  • Renamed the binary to 'gcamzwo'. v0.330 (2023-07-20)
  • Implemented the fm command (F1,F3 overlay).
  • F9: send 'gpsha#' to the TCSIS, where '#' is the value of 'gm'.
  • F10: send 'gpfld#' to the TCSIS, where '#' is the value of 'gm'. v0.328 (2023-07-18)
  • Added the following FITS keywords (requested from the TCSIS) RA = ' 12:49:52.0' DEC = '-29:05:00.0' EQUINOX = 2023.54000 ST = '12:50:33' HA = '00:00:42' ZD = 0.1529 AIRMASS = 1.000 TELFOCUS= 0.0 ROTANGLE= 0.0 ROTATORE= -90.2 GUIDERX1= 13.000 GUIDERY1= 14.000 GUIDERX2= 15.000 GUIDERY2= 16.000 TELGUIDE= '10' v0.326 (2023-06-27)
  • Improved the fitting routine for faint objects.
  • Fixed the "gm" command (guider mode). The 'gm' parameter is the guider number by default. It is used in the "gpaer#" command in "mm2" mode. v0.323 (2023-04-28)
  • Implemented hot pixel masking (mask on,off,#).
  • Added "sm" (display smoothing) and "gain" value boxes below the "span" box.
  • Changed the color of the cursors from black to light grey and the thickness from 2 pixels to 1.
  • Automatially set the gain to "high" (300 50) at startup of the GUI. v0.317 (2023-01-20)
  • Fixed time related FITS records when sending frames.
  • Added keywords to FITS header CAMERA = 1,2,3 // $(-g #) FRAME = 123 // sequential send frame number ROTATORN = 1..5 // rotator port number v0.316 (2023-01-19)
  • Added keywords to FITS header MASK = 1 // fixed CA = "-a" + 180 // (0..360) SH = 'sh #' // value from command
  • Send FITS files to SH-host (was 'gcam' format). v0.315 (2023-01-17)
  • Allow 'elsign' to be zero (elsign = +1,-1,0).
  • Set the TCS port to 5810+rotatorPort (-p switch) If the rotatorPort is '0' (default) the TCS port will be 5801.
  • Changed some defaults: -r: 'rosign' = -1 -e: 'elsign' = 0
  • Take care of some more compiler warnings. v0.314 (2023-01-10)
  • Fixed some compiler warnings on Povilas' Ubuntu machine. Warnings (eg. -Wunused-result, sprintf_check). System call open(,O_CREAT,) requires the permissions as the 3rd parameter. v0.313 (2022-09-09)
  • Added cooler power percentage next to the temperature on the GUI.
  • Default to 'TEC=off' at startup (no temperature control).
  • Default to 'mm1' at startup (mouseMode=1: move box).
  • Display the "GuiderCamera" number 1,2,3 ('-g' switch) on the GUI. This parameter is used for: Defines the IP-port number at the sendHost (5699+g) Defines the prefix for the FITS files, eg. gdr1_NNNN.fits ('write' command).Sets the default guider mode ('gm').
  • Implement the 'gm' command ('guider mode' 1=PR,2=SH,3=SV). In 'mm-2' (mm2) mouse mode this is the probe parameter of the 'gpaer' command. Eg. 'gm3' moves both probes (slitviewer mode).
  • Added the '-s' switch to preset the SH-image SendHost.
  • Use a separate 'sendFrame' number when sending images to the SendHost.
  • Added the '-p' switch to define the 'rotator port'. This will define which guider-stage to send "F9/F10" commands to (TBD). This number has currently no other significance. v0.312 (2022-08-24)
  • Write the serial number of the ASI-294 camera to the FITS header, eg. INSTRUME='ZWO_ASI294MM_PRO / 1f3a0e0301010900 Note: This version requires zwoserver v0031 or newer. v0.311 (2022-08-09)
  • Allow multiple instances (removed the lock-file).
  • Added command line switches to modify the 'PA' calculation (camera angle). -a: constant angle [default=-120] -e: elevation sign +1 , -1 [default=-1] -r: rotator sign +1 , -1 , 0 [default=0] PA = angle + elsign*ELEVATION + rosign*ROTATORE v0.310 (2022-07-11)
