Saving stacked images

#1

Post by AMIF »

Is it possible to save 16 bit stacked images in one folder for further photometry and light curve processing?
Ideally - stacked, calibrated and plate solved :)

SC creates new folder for each stack. It is correct, but very unsuitable in this case.

Hi,

you can change a lot of things about how the files and folders are named by using the 'filename templates' settings - see https://docs.sharpcap.co.uk/4.1/#Filename%20Templates . You will most likely be able to use this to set things up the way that you want, but you will need to take care that that elements like the date and time are included in the filename to avoid the possibility of overwriting previous files due to the same name being generated again and again.

cheers,

Robin

Thank you, I tried to add time in the end, but SC does not avoid changing:
{DateTime:SZ}\{TargetName}\{AutoSave}\Stack_{BitDepth}bits_{StackedFrames}frames_{TotalExposure}\{Time:Z}

Hi,

I think the problem is that you have the '{DateTime}' bit still in the folder name - move that later into the file name part (after the last \) and you should be fine - something like

{TargetName}\{AutoSave}\Stack_{DateTime:SZ}_{BitDepth}bits_{StackedFrames}frames_{TotalExposure}

cheers,

Thank you, I got needed settings finally :)

I use old HEQ-5 without guiding with 1.8 m focal length Mak, so stacking is the only way. BTW, does SC detect and exclude bad images before stacking, or stacks each one?

Thank you, Robin, I tested your string carefully and got a bit of strange result:

1. There are 16 and 32 fits (and text) files in the folder Capture:
Stack_2025-04-05T15_38_27Z_16bits_20frames_60s.fits
...
Stack_2025-04-05T15_38_27Z_32bits_20frames_60s.fits

2. There is subfolder AutoSave in the folder Capture, which keeps just 16-bit fitses. I need exactly 16 bit, but they are shorter:
Stack_2025-04-05T15_37_00Z_16bits_19frames_57s.fits

As I understood, it is impossible to avoid unnessesary 32-bit files, but is it possble to save 16 bit without duplication?

OK OK, without AutoSave folder all works fine:
{TargetName}\{DateTime:S}Stack_{BitDepth}bits_{StackedFrames}frames_{TotalExposure}

Hi,

glad you have it sorted. You can actually control what file types are saved when the auto save happens - check out the 'settings' tab on the far right of the live stacking area to make adjustments if you need to.

cheers,

Robin
