  • HI Colin, I think you need to dig a little deeper. Rejection of all the signal indicates there is a quality or signal difference between the frames you are integrating. You need to look very carefully at the registered data and make certain there ar…
  • You need to always provide the original integrated XISF file. By saving the file- you can potentially mess things up... maybe.For example, the TIF file does not have an astronomical header. It will not have the astrometric solution.  Could you pleas…

  • Well.. I was going to look at the data before the integration.. but the integrated image is fine as well. Can you make this image available to me for download?Upload to a cloud server (any)... make the file permission available to anyone to download…

  • Post a screenshot of some registered data? I have two videos on this:https://www.adamblockstudios.com/articles/spcc-not-enough-samples-error andhttps://www.adamblockstudios.com/articles/spcc-not-enough-samples-error-another-example If you search fo…

  • Yeah..the cold finger would do that.. but in your case the nearly perfect ellipse was remarkable.-the Blockhead

  • Dave, We can have a more detailed discussion off line. I do not think I was being misleading. My point was that a path of HT MTF followed by HDRMT may be shorter/different than attempting to manage the contrast at the high end via GHS which is somet…
  • I looked at the files. This appears like something is wrong with your camera.Perhaps the TEC or cold finger is causing an issue. -the Blockhead

  • Did the individual flats show anything?That is pretty bizzarre.-the Blockhead

  • Well... let's just say some questions I can answer in my sleep... :)-the Blockhead
  • You should try GESD. The result should be different in this case.(if it is what I think it is)-the Blockhead

  • Correct. SubFrameSelector will do the measurements to the files and insert the information in the headers. -the Blockhead
  • Without diving into the data and looking at all of the calibration data, the raw data, the calibrated data... etc it is hard to say exactly.  However, this has the appearance of a rejection issue (usually when using Winsorized Sigma Clipping). That …

  • This is an OK scenario.In WBPP measurements are made immediately after the images are calibrated (and cosmetically corrected). However, WBPP *knows* it looking at already calibrated data that has not yet been measured. In fact WBPP doesn't even want…
  • I have a video about this demonstrating it. I can't remember where right now..but I think I did an update to demonstrate. The difference is when you are working with a RGB (multichannel) image compared to a grayscale image. To see the values that yo…
  • I think you need to ask a specific question... something that doesn't make sense to you? Do you understand, for example, when you save files to your computer (physically on the disk as XISF files)- you can see the process instances and the settings.…
  • Projects save every image you have on the desktop (in workspaces) as well as all of their history states. Also saved are the settings for any open processes and all process instances (icons) on the desktop. It pretty much saves everything so you can…
  • Matt, When you encounter a situation like this... please skim the "Pixnisight Path" in Fundamentals. It has the most up-to-date explanations of things including this stuff on astrometric solutions and SPCC. In fact, even FastTrack training was updat…
  • Hi Terri, Since I may make this available as a stand alone thing- I thought it best to approach the topic as if people had not seen the information before. -the BLockhead
  • Stuart, Are these data CFA images?Did you make certain both the Flats and Lights have CFA checked? I would configure WBPP in the proper way (based on your thinking) and then generate ALL of the WBPP screenshots using the diagnostics button. Your man…
  • In this situation the pipeline (WBPP) is usually trying to tell you something is likely wrong with your data. It could be a calibration problem... an oversubtraction/pedestal problem... or perhaps simply poor star quality and resorting to the multis…
