Hi Geoff, I think I might be starting to see where this is coming from - it is sending a custom tracking rate as part of turning the tracking on, and that custom rate is the -15.??? one that is out of range. I can sort of see why, but not quite sure what has changed yet, but got it down to 1 or 2 pl...

Hi, I think the most likely cause would be the minimum altitude filter as shown here : https://docs.sharpcap.co.uk/4.1/#Choosing%20a%20Target%20from%20the%20Full%20Catalog Note that the first dropdown of common targets as shown here - https://docs.sharpcap.co.uk/4.1/#Choosing%20a%20Target - only con...

Hi Bertrand, thanks for sharing the files - I think I understand a bit about what is going on now... Looking at the bright frames in the image, they seem to occur regularly about every 115 frames (at frames 66, 189, 297, 412, 526, 641, etc). At the frame rate of 87fps of the file, that corresponds t...

Hi, you can see how to create and use custom catalogs here : https://docs.sharpcap.co.uk/4.1/#Custom%20Catalogs%20and%20Objects However, NGC3621 is in the default catalog (I just checked), so I suspect that it didn't appear in the list of targets because one of the filters on altitude, brightness, e...

Hi, have you turned off the stretch functionality there (either delibrately or accidentally)? That would disable the auto stretch and reset buttons. The button above the auto-stretch is the on/off button for the stretch - if it is green the stretch is turned on, if red it is turned off. The idea of ...

Hi Phil, OK, that's all starting to get a bit odd. Can you test the status of the camera and its drivers using USBTreeViewer please? You can download this useful tool from : https://www.uwe-sieber.de/usbtreeview_e.html Once running, it shows you lots of details about the USB devices plugged into you...

Hi, in the latest update, I did add some extra access to try to cover your previous list of missing things - you can get at those using SharpCap.LiveStacking.Guiding SharpCap.LiveStacking.FrameFiltering These two new objects allow access to the guiding and frame filtering settings that were previous...

Hi John, well, FITS is significantly slower to write than SER, so if you were taking lots of saved frames quickly then you could build up a queue of frames ready to be written to disk. In the worst case, if the SharpCap memory buffer fills up completely then frames would get dropped without saving b...

Hi Geoff, ok, thanks for the logs. If you do work out which version breaks it then do let me know, as searching for the changes between two consecutive versions will hopefully narrow down the possibilities for the cause very quickly. The logs do look promising - in the one with the slew, SharpCap tr...

Hi, there are generally 3 main slider controls to adjust - exposure, gain and black level (sometimes black level will be called offset or brightness). It's usually best to leave other control (sharpness, gamma, colour adjustments, contrast, etc) at their default values. While adjusting those other c...
