  1. I am not sure that you can use White Balance to remove light pollution from wide angle images. It may be better to use a clip-in LPS filter and then fix the color balance in post processing.
  2. I tried to duplicate Daniel's issue with my T5i and BYE 3.1.3 on my Win 7 x64 desktop and was not able to re-create it. I had Planetary/LiveView exposure set to 2", captured a 100 frame video, switched to imaging, captured a 40 second bulb exposure. I heard the mirror go up at the start of the exposure and back down 40 seconds later. I repeated this test with the Max Sensitivity setting checked on unchecked. It made no difference. I hope that the log file reveals the root cause.
  3. I was wondering if Daniel was confused about the imaging settings only being set when an exposure is shot. However the issue that he appears to be reporting is that when he has the set the capture plan time to some BULB value and starts the capture plan, only a 2 second image is taken and downloaded but that BYE hangs until the exposure was expected to be complete. I have asked what camera model he is using and whether he is using a separate shutter control cable. I was wondering if he has an old camera where the second cable is needed for BULB exposures. As far as I have read, he has never provided that information.
  4. Look at this related post --> http://www.otelescope.com/index.php?/topic/931-files-are-only-saved-to-pc/#entry6248
  5. Jerry, The observatory is functioning well. Thanks!

    windows 10

    Jim, What makes you think that it is not supported? The T3i is a DIGIC IV camera. it may no longer be manufactured, but it does appear to be supported. It is listed as a supported camera in the 2.15 version of the Canon SDK.

    windows 10

    Jim, A better question is...Will Windows 10 be compatible with Windows 7 and 8 applications? The answer is yes, with near 100% security. Microsoft would be skewered by the user community if this were not so. Not so certain is whether Windows will supply drivers and recognize all the cameras that it does today. This is not a BYE issue!
  8. Jerry, Windows tries to prevent applications from "always being on top". Microsoft used to allow that behavior but it caused a lot of frustration so they now try to prevent it. Your best bet is to make the BYE and PHD windows as small as you can, and then click on the applications' task bar icons or the windows themselves to select which one is on top. I typically put the PHD2 window on the right and the camera capture window on the left. The camera capture window (sometimes BYE) overlaps PHD2, but I can see the right most 75% of the guiding graph which is what I am most interested in. This is on my 17" laptop, so it may have a greater resolution than your 15", but not necessarily.
  9. Phil, First, did you mean that you upgraded to BYE 3.1.3? If not, you should do that. If the image is all white, then either your camera is malfunctioning, or you are overexposing the target. This would happen if you took a shot during the day, but used longer duration, nighttime, settings. It will help to understand what your target is, what your telescope (aperture and focal ratio) is, and what the shooting parameters (duration and ISO).you are using.
  10. Mike, The sensor temperature is extracted from the image EXIF data by BYE. So any issues with the values are not an SDK issue, nor is it a BYE issue. This is purely a camera function. I do not know whether Canon publishes the specs regarding when, during an exposure, the temperature is recorded. It may be easy to discover more about this, however. With the camera stable at ambient temperature, take a very short exposure, followed by a 900 second exposure, then followed by a very short exposure. Compare the recorded sensor temperatures of the three images. If the temperatures that were recorded in the first 2 image are essentially the same then you could infer that the temperature for the long exposure was recorded at the start of the exposure. If the temperatures of the last 2 images are essentially the same then it is likely that the temperature of the long exposure was recorded at the end of the exposure. It is normal for the sensor to heat up with use. This will cause the sensor temperature to increase, even while the ambient temperature is decreasing. This is simply because the camera heats up while the shutter is open. There are many factors that cause this behavior, including heat that is generated by the sensor itself, along with the LCD display potentially being on, or the battery discharging. When I shoot darks, I shoot enough that I can discard the first few images that were taken while the temperature is stablizing.
  11. BYE gets the value for the battery indicator from the Canon SDK and so BYE can only report the data that the camera and SDK make available. I would suggest replacing the battery with an A/C alternative, if you have 120V power available. It will also help your camera to run cooler.
  12. You can re-size the BYE and PHD windows and position them wherever you need them. They can be on different parts of the screen or overlap. Whichever window you select will be on top. This is behavior is totally controlled by Windows, not by either BYE or PHD.
  13. Does the Mac recognize that the camera is connected? If so, does Windows recognize that the camera is connected?
  14. Plug the USB cable into the A/V Out jack.
  15. Yes, long exposure noise reduction (individual dark frames) are applied to all images (RAW and JPG). BYE is tolerant of having LENR turned on, but it cuts your productivity in half because every image takes twice as long to expose and download. Your are better to shoot darks at the end of the session or use a master dark library frame that was previously taken.
  16. Daniel, What version of BYE? If not 3.1.3 then you should upgrade to 3.1.3, and try again. What model of camera? Are you using a serial cable for BULB exposures? Are you trying to use mirror lockup?
  17. I believe, based on the scant information that you provided, that your issue is due to pilot error. Do not uninstall AstroTortilla. It does NOT make any permanent changes to BYE. AT only asks BYE to capture an image. The duration of the image is specified on the AT screen. Un-installing or re-installing AstroTortilla will not impact the operation of BYE in any way. Some Canon cameras have separate mode settings for Bulb and Manual, but for most of them Bulb is not a shooting mode. I will assume that your camera does not have a separate BULB setting on the dial. There are 2 different settings that you can set to capture a 10 second image with BYE. The first is to set the Shutter dropdown to 10". This will capture a 10 second image with the exposure being timed by the camera. It will work if the dial on the top of the camera to the right of the viewfinder is set to either M or Tv. The way to take a 10 second exposure is to set the Shutter dropdown to BULB and the duration to a value of 10. This will also take a 10 second exposure, but when the shutter is closed is controlled by BYE. So when you tried to take a 10 second exposure which settings did you use? What mode was the camera set to (Tv pr BULB)? What camera are you using? Which version of BYE (there have been 3 updates to 3.1 so specify all 3 numbers!)? The more information that you provide, the better the help that the community can provide.
  18. Perhaps using the POTH handset to do your nudges would eliminate the need for the native iOptron app. POTH is installed with the ASCOM Platform so you already have it.
  19. Look at the top of the page for this site and click on the 'Upgrade' link in the menu. It will lead you to a page with upgrade instructions, depending on which version you were using on the old PC.
  20. David, How would the FWHM value be used by an outside software package, specifically your focuser? for auto focusing? what workflow do you envision? Half-Flux Diameter (HFD) is probably a better metric to use for focusing, but that is just a side comment. Guylain has said that he will eventually add automatic focusing into BYE/BYN. In that case, what is the benefit to providing focus metrics to outside apps? Also keep in mind that when LiveView is active the focus metric value changes frequently, but it can also be updated when snap images are downloaded. Which would you use? LiveView? snapped image? both? Your app could be structured like AstroTortilla to ask BYE to take a picture. Then your app could analyze the picture to extract the focus metric. Your app would, in effect, be re-creating FocusMax, in effect, but would add value if done correctly since FM is limited in how it gets images. Back in March I was trolling the FocusMax 4 support forum and I read that someone had asked about FM integrating with BYE. Steve Brady indicated that the had never heard of BYE. I put in my 2 cents about the benefit of such an integration, but got no reply to my post.
  21. The DSUSB cable is only used to control the shutter for computer-controlled BULB exposures, so I don't think that it is used for LiveView control. I would try operating BYN without the DSUSB cable (only the regular USB control cable). Test that LiveView still works and then try taking short exposures to see if the camera is controlled correctly for non-Bulb exposures that are shorter than 30 seconds. You do not need to have the camera connected to a scope to try this, so you won't have to wait for, and waste, imaging conditions for this testing. Once you have determined that all is working for short exposures then connect the DSUSB cable between the camera and the PC (but do not disconnect the USB control cable) and configure BYN to use the DSUSB cable. If you look back through the BYN topics you will see a mix of people with a similar issue. In a few cases the issue was a bad DSUSB cable. In most cases it was due to incorrect configuration of the DSUSB cable or the fact that when people connected the DSUSB cable they disconnected the USB cable. The DSUSB cable is used only for shutter control during BULB exposures. The USB cable is used for downloading and the remaining camera control functions.
  22. I was also dismayed when I figured out that the Celestron NexRemote application does not work with the hand controller, it replaces it! I was worried that if my PC crashed that I would have to re-align the scope after I got it restarted. I removed NexRemote from my PC and have never looked back! I don't use my CGEM for imaging very often but when I do, I use a planetarium program (Sky Tools 3) for slewing to target and something like BYE's telescope interface to nudge the mount for framing. The good news here is that the Celestron driver supports multiple simultaneous client connections so that both BYE and Sky Tools can be connected at the same time.
  23. So, your LiveView does not work even when not connected to a PC?
  24. Is the USB cable that you are using a cable that you have tested and know to be a good cable? Is it shorter than 15 ft? Is the memory card in the camera empty? The Nikon SDK wants to read the list of images on the memory card before it completes the connection. From reports, this can take quite a large amount of time. The fix is to make sure that the card is empty (no images). And it may be helpful to reboot the PC, as Guylain has suggested.
