  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. So, your LiveView does not work even when not connected to a PC?
  7. 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.
  8. That would be a good reason to create a library of darks at different exposures and temperatures. You could also use a "flip flat cover" for shooting flats and darks as well as for use as a dust cover if you are using a compatible OTA.
  9. Basically, yes but while LiveView is active, the shutter is always open so the frame rate is the exposure, but not a "shutter speed".
  10. For operation with LiveView active the exposure is not like a normal shutter speed and does not affect the frame rate in any way. It is a brightness or gain adjustment that the camera applies to the image. You want the image to be dark, but light enough that you can see the equatorial bands. You should experiment with different values. You can stretch the image after the frames have been stacked. It is pretty normal that the planet moves around when viewing the AVI file. That is why you capture so many frames. The stacking software (RegiStax or AutoStakkert, for example) will grade each of the frames and only select the best frames for stacking. This allows you to take advantage of brief intervals when the seeing is not as bad to get a sharper image.
  11. The frame rate is basically as fast as the camera can read out the sensor and download it to the PC. It is limited by sensor size, the DIGIC processor, and available USB bandwidth. As Guylain said, you would use the Exposure and ISO in Frame & Focus, Planetary, and Drift Align modes to control the brightness of the downloaded LiveView frames.
  12. You can purchase an additional license on this site in the Store. Is there some other issue?
  13. I have followed the process outlined by Dr. Clay Sherrod here --> http://www.jatobservatory.org/OpticsCleaningSystem.html I have also purchased a kit from here --> http://www.photoniccleaning.com. It works well for eyepieces but I have never used on glass as large as a corrector plate or objective lens.
  14. You could also try installing and using the Canon EOS utility. If you have the same issue with the EOS Utility, then it would tend to eliminate BYE as being the problem. It is most likely a problem with the USB cabling. If you don't have the proper .Net Framework, I would expect that BYE would not be able to start up.
  15. I don't think that anyone has tested the 810A, but the 810 was tested and does work well with BYN. If you have the D810A, you could download the trial version of BYN, test it for 30 days, and report back here on your results.
  16. According to the information on Camera Support Grid the D750 supports BULB, but not mirror lockup. BULB should work with only the single USB cable; a second shutter control cable (DSUSB) is not needed. What is the issue with BULB? What are you doing and what do you see? IMO there is no big loss as far as mirror lockup is concerned.
  17. You should make sure that you are using the latest release of BYN (version 1.0.1). It was released about 2 months ago.
  18. This is a question about Backyard Nikon and should have been posted in that forum. According to the Camera support grid, the D90 requires 2 cables for full operation. The Shoestring DSUSB shutter control cable for bulb exposures and second USB cable for everything else.
  19. Haven't others reported a similar issue that was traced to an issue with camera/SDK not reporting that an image is ready to be downloaded, so BYE just sits there waiting?
  20. On my T5i repeatedly pressing the Info button (Disp on the T2i), while otherwise idle, cycles through 3 displays. One of those is a blank screen (off). If I set it to off before starting a capture plan, it stays off while capturing. I hope that it is something similar with your T2i. If the display is showing the shooting parameters when I start capturing a BULB exposure, the display shows the elapsed time (minutes & seconds) since the start of the exposure in the lower right corner. Having the display be totally dark is a very important when shooting in a HyperStar configuration. ImagesPlus and BYE both use the Canon SDK so one would think that any differences would be due to the details of how each of the applications uses the SDK to control the camera. Based on my testing of BYE 3.1.3 and ImagesPlus Camera Control (IPCC) 5.75 the behavior of the applications is indeed different. When my T5i is first connected to my PC the LCD display is dark (off). When I connect to the camera with BYE, the display is turned on. When I connect with IPCC the display stays off and never turns on while the camera is connected. So, there may be some property in the SDK that allows both behaviors. For me, I prefer BYE's functionality as it allows me to access the cameras menus while the camera is connected to the PC and the application. I hope the above workaround is effective for you and your T2i. If there is indeed a camera property that can turn the LCD display on and off then it may be useful to expose this property as a setting in BYE to allow the display to be controlled by the user. Most of the time off is good, but being able to turn the display on to review and change settings my be convenient in some cases.
  21. Patrick, Snap images are JPG files that you would take for framing and/or focusing. They are only useful for that purpose if they are downloaded to the PC. If they are stored in the camera they are not useful for focusing, so that option is not provided. According to the Camera Support Grid the 100D/SL1 supports MirrorLock via the USB control cable (a second shutter control cable is not needed). If you want to flip up the mirror, wait for some time and then start imaging you only need to specify a non-zero mirror lock time in the Capture Plan Center on the Imaging screen. Myself and others have previously posted the recommendation to avoid using mirror lockup when taking long duration photographs. It is not necessary. Even if there is some vibration from the mirror flipping up, it should only last a very short time. Any effect of that short period of vibration would be overwhelmed by the subsequent data. So, BYE does support it, but you will not see any difference in the finished images. I hope this helps.
  22. The T6s is not yet supported in BYE, per the camera support grid here. Once a new version of the Canon SDK is available to Guylain it does not usually take him too long to release an updated version of BYE. He may ask owners of new camera models to beta test the new version of BYE before a general release. It does seem that Canon does not always release an new version of the SDK to the whole world simultaneously. For example, they may release a new version to Europe and Asia before releasing it to North America. Be patient.
  23. I would suggest re-installing BYN to a different directory and then try running the new installation. Are you sure that the DSUSB cable is correctly connected and working? Also, if you look at the camera support grid for BYN, it says that the BYN has never been tested with a D3. I am sure that Guylain will chime in tomorrow.
  24. The version of BYE older or newer, Classic or Premium should not impact the ability to use LiveView for Frame & Focus. The LiveView frame rate is probably around 20 frames per second. This means that the true exposure (less than 1/20th of a second) is very short and only very brightest stars in the sky will be visible. My recommendation is to point at the brightest star that you can see (Arcturus??), use manual techniques to get close to focus, then connect with BYE. To make the star as bright as possible on the screen, either select the Maximum Sensitivity setting on the Settings dialog or change the LiveView exposure to 2 seconds (2") and crank up the ISO to its maximum value. You should then be able to just barely see the star in the field. If you think that the star should be there but you cannot see it, then you should try taking a short 1-2 second Snap picture. That should show you where the star is (or isn't) in the field.
  25. If you do not see the camera in the Windows Device Manager then BYE will not be able to connect to it. That may be a Windows problem or a cabling problem. The camera was powered on, right?
