vup
se6astian: looks good from what I can tell
01:15
vup
what was the motive for this?
01:29
vup
ohhhh
01:29
vup
I just figured out why the flatfields were so weird
01:30
vup
I fucked up the pixel order
01:30
vup
Now I also finally get the row noise
01:31
vup
it looks like maybe the flatfields are not completely "flat"
01:31
vup
https://files.niemo.de/flatfield_example.png
01:31
vup
now all the "weird" pixels are either on all color channels in the upper left corner, and the complete odd rows and even cols color channel
02:32
Bertl_oO
the upper left corner looks like an illumination issue, i.e. a shadow or reflection on the sensor
02:47
vup
yeah
03:04
vup
se6astian: so with the averaging built in, doing 1024 or even more should be easily doable, right?
03:23
Bertl_oO
off to bed now ... have a good one everyone!

good day
08:27
se6astian
the motive was darkframe IIRC
08:27
se6astian
great that it works
08:28
se6astian
and that you discovered the issue!
08:28
se6astian
for the flatfields some vignetting and light differences on the wall are indeed unavoidable yes
08:29
se6astian
yes 1024 frames with averaging is super convenient
08:30
se6astian
https://files.niemo.de/flatfield_example.png <- also looks like there is some residue on the sensor (the round spots)
09:55
anuejn
vup: very nice

morning folks!
14:27
anuejn
morning :)
14:58
vup
se6astian: yeah looks like it re residue
15:04
vup
interesting then, that the dark columns are that much darker than the rest of the darkframe
15:36
vup
se6astian: do you still have any of the 2048 width darkframe stacks?
15:36
vup
now that I actually get row noise it would be interesting to try and correct it
15:41
se6astian
no I think I deleted everything in the cloud in that folder
15:41
se6astian
can check on recorder inn the evening though
15:41
se6astian
but I can just capture new ones of course
16:08
vup
right, no problem, would be interesting to investigate the row noise
16:18
Bertl
off for now ... bbl

se6astian
vup: starting darkframe stack collection now
19:39
se6astian
1024 frames averaged leads to this error though midway
19:39
se6astian

19:40
se6astian
using 256 frames for average for now
19:40
se6astian
works fine this way
19:54
se6astian
vup please check: https://cloud.apertus.org/index.php/s/aJwdQ9BHQnm4k4p
19:54
se6astian
all darkframes in 2048 width with black coloumns on
19:54
se6astian
256 averages each + snaps
20:35
vup
will check later
20:35
vup
Re the oom error, did you update to the latest version?
20:38
vup
(commit 575b540)
20:39
se6astian
I did git pull yes
20:40
se6astian
will double check the commit name tomorrow
21:28
vup
Hmm curious
21:29
vup
With the latest version there should not be any difference in memory usage between 256 and 1024 (or any number greater than the number of cores for that matter)
22:50
se6astian
the error keeps returning at around 480 frames averaged
22:53
vup
Interesting
22:53
vup
anuejn: was reporting memory leaks aswell, but I have none...
