  1. I doubt that your issue is due to the image size since a 5 second RAW and a 5 minute RAW are about the same size. It would be more of a problem if BYN could not download RAW images to the PC. This is the most common operating method for deep sky astrophotography. I am a Canon owner and it is only very rare and special cases that I would connect my camera with my PC and control it with BYE, but not save the images to the computer. I want to see the images while I am imaging so that I can adjust focus, or change the imaging plan to take more or fewer images.

    Also, by default, the Canon SDK does not use a wireless connection. So you must disable Wi-Fi in the camera and connect a USB cable between the camera and the PC. If you search this forum you may find other folks who have been able to pair the camera to the PC via a wireless connection outside of BYE and then BYE and the Canon SDK can connect wirelessly.
  3. However, the downside of saving to the camera is that you don't get to view them on the PC as they are being taken. It should take about 10 seconds to download an image from the D800 to the PC. That is reasonable given the size.
  4. I am not a Nikon owner, so I apologize for not mentioning this sooner. The D800 has 2 memory card slots; an SD card slot and a CF card slot. The camera can be configured to use those cards in different ways. I would suggest testing BYN with different memory card settings. I would select choosing the SD card as the primary card and use the Overflow option so that both RAW and JPG images are saved to the SD card until it is full. I would also make extra sure that neither card is write protected. In other words try each configuration without the camera being connected to the computer. If you get it to work, please come back here and let us know what configuration(s) worked and what configuration(s) didn't work.
  5. So just to recap...With your D800 and BYN 2.0.10 you are unable to save RAW BULB exposure images to the camera. Guylain may ask for a log file where it fails to do that. It is best to delete the old logs then start BYN and go through the steps to take a bulb image with save to camera selected. Then follow the instructions at the link below to send the log without posting it here.
  6. There is a similar request in the Feature Suggestion Box Forum for short exposures of arbitrary length, timed by the PC not the camera. The use case is for eclipse photography. It should be possible because other programs offer similar functionality. Here is the post from the Suggestion Box: I don't know about repeatability of very short exposures (eg < 1 second), but you should be able to use a high resolution timer (.NET Stopwatch class or the Win32 performance counters that are in kernel32.dll) for repeatable exposures of 1.8 seconds as has been requested. It is worth investigating and perhaps putting out as a pre-release feature to see what users think of it.
  7. Does BYN fail the same way when you save your images to the PC? I believe that there are some BYN issues when saving to the camera. Or perhaps I am mis-remembering and it is with saving both RAW & JPG. In any case it is simple to try saving RAW only to the PC.
  8. Do you perhaps have Long Exposure Noise Reduction turned on in the camera? If so, this doubles the exposure time because it causes the camera to take the dark frame after each light frame. BYN does not know this and will fail if the camera does not report that it is ready for the next exposure in a timely manner. Conventional wisdom is to turn off LENR when doing astrophotography, as this automatically doubles your productivity, and take your dark frames separately.
  9. Thanks for letting us know that you have a solution.
  10. Be sure to download the latest pre-release version of BYE.
  11. Scroll to the bottom of this page and click on Download below BackyardEOS. Then at the bottom of the list on the right side of the page, click on Pre-releases.
  12. If you have an autofocus lens on the camera with the lens in AF mode, you should be able to drive lens in small increments from BYN. Then once critical focus has been achieved you need to tape the lens in place and switch it to Manual Focus so that the camera will not try to focus at the start of the exposure. At least this is how it works with my Canon. The advantage of using BYN, rather than the camera's LCD display for focusing, is that BYN measures the diameter of the stars and provides a numerical measure of how good your focus is (FWHM or HFD). LiveView frames are shown very quickly. I don't know how you could adjust any faster or better by using the small LCD display on the camera. The 2 second delay in BYN's capture plan goes before the start of the first exposure in your capture plan. It is not a mirror up delay. BYN does not support Mirror up delay for any camera; at least according to the Camera Support Grid on this web site. I believe that the authors are working to try to support this feature. If you are doing long duration deep sky imaging then mirror lock is totally unnecessary anyway. Not sure where you are seeing exposure times that include the 2 second delay. Please explain. The camera has no concept of a dark frame (except for Long Exposure Noise Reduction) and does not allow you to take dark frames by keeping the shutter closed. It is up to you to prevent light from reaching the sensor. This is usually accomplished by covering the lens, or removing the lens and replacing it with the body cap.
  13. Please be patient. You provided info that admin needed just a few minutes ago. He needs to incorporate those numbers into the program and provide a new pre-release version for you to try. He will post back here when a new version is available for you to test. You are correct about the SDK's non-support for WiFi and the fact that you must turn WiFi off in the camera in order for USB to work. The good news is that a wired connection should be faster and more reliable than WiFi.

    Mirror Up

    When doing long exposure AP, the milliseconds of vibration, if there is any vibration, are overwhelmed by the following several minutes of exposure time. This makes mirror up unnecessary for that type of imaging.

    Mirror Up

    John, I found the old thread that you referenced. It appears to end with no confirmation that Guylain's changes have solved the issue with Mirror Lock on Nikon cameras. This lack of feedback is likely why the support grid still does not indicate mirror lock support. It is not clear whether the current pre-release supports that capability, but it may be worth trying. If you do try, regardless of the outcome, please report what you have found. While mirror lock is not particularly useful for deep sky astrophotography, there may be other uses where it is beneficial. Even though nobody else volunteered to test the mirror lock support in BYN, other photographers my be looking to utilize it.
