  1. How do you seal the chamber to prevent condensation?
  2. Do you use Wisky for mount control? Sent from my iPhone using Tapatalk
  3. I set fps to about 0.2sec. (one frame in every 5sec). I also have Skychart in another channel. The cpu load is 25% max on a quad core Atom pc (Minix Z64) with 32bit win 8.1. I use Teamviewer for remote control. My usb cable is 6m long. I never have any stability issue. It runs for several weeks already. I guess Ezplanetary is stable on 32bit os.

  4. I use usb-powered heat pads in beneath the dome. I can get about a 20C delta.
  5. FYI, I use EZplanetary with Win8.1 (32bits). I haven't had the freezing issue so far. I have both QHY5Lii-mono and QHY5Lii-color. In my opinion, the color version may be more suitable as an all sky camera because 1) during daytime, we can differentiate the blue sky and dark cloud. 2) during nighttime, we can differentiate stars from noise. Noise is in color but stars are white. The dew heater should not be in contact with metal otherwise heat is absorbed by metal. ABS plastic is good for insulation. Best regards, Anat
  6. It works. It takes about 10-15 mins in EZplanetary to lower exposure times in early morning from an oversaturation state. I wasn't patient enough previously I found mask files inside C:\Program Files (x86)\QHYCCD\EZPlanetary\EZPlanetary\LUTMAP It may be possible to change the coverage area for auto exposure Best regards, Anat
  7. BTW, do you use QHY5-ii or QHY5L-ii ? Anat
  8. Thank you. I use EZpanetary 3.7.8. So I will try the former version. I also use the high compatibility driver (Ver. 14-12-12). Best regards, Anat
  9. Many thanks for sharing your idea. I follow your idea I also run Skychart (CdC) in parallel and show a live skychart. Blue Iris for iOS is very handy to show both allsky and skychart image. I still struggle with setting proper values in EZplanetary. Could you tell me your values of - gain - exposure (there are ranges to choose (us, ms, s). It seems that AEC won't switch across the preset range. So It is difficult to make the camera works for both daytime and nighttime. - gamma? Do you enable AGC ? Thank you. Anat
  10. And you can just run "make" after modifying guider.cpp. Anat
  11. Patrick, Guiding will try to minimize the error to Zero and finally cause fluctuation about zero. If we have an initial offset, the graph will approach zero in one direction. If we properly set the P gain (slightly low), the graph will not aggressively come to zero. The following graph is my result for DEC guiding. Originally, I added the two commands in order to bring the reference axes to the selected guide star otherwise the selected guide star is far away the reference axes (resulted from the calibration). So I modified the code to move the reference axes before guiding. I "borrow" the dithering parameter to adjust the offset amount. Don't worry. Dithering will not happen because it must be commanded via the socket command Best regards, Anat
  12. I have played with RPi for a while. This is my project http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Board/computers/Number/5369851/page/0/view/collapsed/sb/5/o/all/fpart/1 http://sourceforge.net/projects/iastrohub/
  13. Hello, You will need to add these commands at the end of "void guider::fill_interface( void )" in guider.cpp // ADDED m_math->get_star_screen_pos( &pos_x, &pos_y ); m_math->set_reticle_params( pos_x-m_common_params.dithering_range, pos_y+m_common_params.dithering_range, -1 );These commands will move the reference axes to the selected guide star but it will apply an offset equal to the dithering range (m_common_params.dithering_range) you specified in the setting menu. By doing so, if you set the appropriate P gain value, the guide star will approach the reference axes only in one direction. It is better than having the fluctuation about zero. Best regards, Anat
  14. I finally compiled CdC on MK808 and use CdC via server commands. This is the plate-solved image overlaid on the skychart The astrometry and CdC is interfaced via a web application.
  15. It is amazing that I can get blind-solved results in 5 sec on MK808. I skip the modification to show the CCD frame for now. So I can work on the integration of plate-solving and CdC first which is pretty straightforward because CdC accepts server commands via a TCP socket: http://www.ap-i.net/skychart/en/documentation/server_commands#v27_compatibility_dde_command
