00:14 | vup | se6astian: looks good from what I can tell
| |
00:15 | vup | what was the motive for this?
| |
00:29 | vup | ohhhh
| |
00:29 | vup | I just figured out why the flatfields were so weird
| |
00:30 | vup | I fucked up the pixel order
| |
00:30 | vup | Now I also finally get the row noise
| |
00:31 | vup | it looks like maybe the flatfields are not completely "flat"
| |
00:31 | vup | https://files.niemo.de/flatfield_example.png
| |
00:31 | 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
| |
01:32 | Bertl_oO | the upper left corner looks like an illumination issue, i.e. a shadow or reflection on the sensor
| |
01:47 | vup | yeah
| |
02:04 | vup | se6astian: so with the averaging built in, doing 1024 or even more should be easily doable, right?
| |
02:23 | Bertl_oO | off to bed now ... have a good one everyone!

07:27 | se6astian | good day
| |
07:27 | se6astian | the motive was darkframe IIRC
| |
07:27 | se6astian | great that it works
| |
07:28 | se6astian | and that you discovered the issue!
| |
07:28 | se6astian | for the flatfields some vignetting and light differences on the wall are indeed unavoidable yes
| |
07:29 | se6astian | yes 1024 frames with averaging is super convenient
| |
07:30 | se6astian | https://files.niemo.de/flatfield_example.png <- also looks like there is some residue on the sensor (the round spots)
| |
08:55 | anuejn | vup: very nice
| |
11:43 | Bertl_zZ | changed nick to: Bertl
| |
11:43 | Bertl | morning folks!
| |
13:27 | anuejn | morning :)
| |
13:58 | vup | se6astian: yeah looks like it re residue
| |
14:04 | vup | interesting then, that the dark columns are that much darker than the rest of the darkframe
| |
14:36 | vup | se6astian: do you still have any of the 2048 width darkframe stacks?
| |
14:36 | vup | now that I actually get row noise it would be interesting to try and correct it
| |
14:41 | se6astian | no I think I deleted everything in the cloud in that folder
| |
14:41 | se6astian | can check on recorder inn the evening though
| |
14:41 | se6astian | but I can just capture new ones of course
| |
15:08 | vup | right, no problem, would be interesting to investigate the row noise
| |
15:18 | Bertl | off for now ... bbl
| |
15:18 | Bertl | changed nick to: Bertl_oO
| |
17:57 | lexano | left the channel | |
18:14 | lexano | joined the channel | |
18:36 | se6astian | vup: starting darkframe stack collection now
| |
18:39 | se6astian | 1024 frames averaged leads to this error though midway
| |
18:39 | se6astian | thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: OomError(OutOfDeviceMemory)', src/pipeline_processing/processing_context.rs:137:14

| |
18:40 | se6astian | using 256 frames for average for now
| |
18:40 | se6astian | works fine this way
| |
18:54 | se6astian | vup please check: https://cloud.apertus.org/index.php/s/aJwdQ9BHQnm4k4p
| |
18:54 | se6astian | all darkframes in 2048 width with black coloumns on
| |
18:54 | se6astian | 256 averages each + snaps
| |
19:35 | vup | will check later
| |
19:35 | vup | Re the oom error, did you update to the latest version?
| |
19:38 | vup | (commit 575b540)
| |
19:39 | se6astian | I did git pull yes
| |
19:40 | se6astian | will double check the commit name tomorrow
| |
20:28 | vup | Hmm curious
| |
20:29 | 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)
| |
21:50 | se6astian | the error keeps returning at around 480 frames averaged
| |
21:53 | vup | Interesting
| |
21:53 | vup | anuejn: was reporting memory leaks aswell, but I have none...
