Hi Bertrand,

if possible the log and the ser file would be helpful to try to see if anything of interest in the log ties in with appearance of the problem in the SER file.

thanks,

Hi, there are lots of causes that might lead to an initial large error (polar alignment, mount alignment, cone error, etc), but hitting the problem after the plate solving correction has tried to put the target into view is less easy to work out. If you are trying to image near the celestial pole an...

Hi, yes, that's right - 'dark flats' are the dark frames matched to the flats - they are used to create a flat with the dark level background removed and not used in place of normal darks. Best to turn dark correction off when capturing flats and allow the 'dark flats' option to do its bit. cheers, ...

Hi Geoff, from the logs it looks like EQMOD is generating an error when SharpCap is asking it to turn on tracking - the underlying error looks like it is a numerical overflow (numerical value too large to be represented properly). I wonder if EQMOD has somehow got a weird tracking rate configured an...

Hi,

at least part of that would be becaue I forgot about this one, sorry

I have now tweaked the code so SharpCap will wait a short while for the focuser to report as connected - this will be in next week's update.

cheers,

Hi, thanks for the report - I think I just need to tweak the way that the buttons are enabled/disabled to allow for the 'unknown' position. The calibrator appearing in the 'NotReady' state is a bit worrying though - according to the ASCOM documentation, that state is supposed to be transient - it me...

Hi, Ok, I start to see the picture. I will have to have a think about that, but for now I can make a suggestion of another place to 'smuggle' data from the sequencer to python that might work out... In the sequencer, use a SET CONTROL step to set the value of the Notes control - ie SET CONTROL Notes...

Hi, not a bad idea, but I would be tempted to put the buttons above/below the slider rather than both at the bottom if I did this. Are you aware that holding down the <SHIFT> key while dragging the colour adjustment sliders (and the other adjustments in the live stack histogram) reduces the speed of...

Hi, light frames and dark frames need to be captured with the same gain, exposure and offset values to work together properly. Flat frames and dark flats need the same settings as each other, but do not need to be matched to the light/dark frames. That means you can use shorter exposures and lower g...

Hi, the first thing to check is the size of the error - the error caused by having the ASCOM driver incorrectly report J2000 will be up to about 8 minutes of arc (depends on the part of the sky you are looking at, but as of 2024, 8 is the maximum - by 2034 it will have increased to nearly 12 minutes...
