Not bad. Nice to see another setup work. livestack might be going a little heavy handed on the color saturation. I might dial that down a bit. How was the performance on the RPi4 in livestack vs siril? |

Also, thanks for the bug reports! Glad to see it working with FITS files generated by a different camera than what I own. |

siril is running on a i7-7700HQ 8 core / 16 Gb / Quadro M1200 graphics
laptop, livestack is on the pi 4+ 8 Gb with a 128Gb SSD drive.
I haven't done a timing but siril is orders of magnitude faster, and that
is fine, since livestack is processing lights as they
come off the camera, in this case it would have been every 30 seconds.
Interestingly, I had taken 5 shots with Ekos and named
the object 'DOUBLE_CLUSTER' and the other 12 shots named 'NGC_884' and
livestack "knew" based on fits header tag to
stack 2 separate sets of images. I cheated it by chaning the fits header
object tag in all files to just 'NGC_884' and had livestack
do all 17 as one set.

and thank-you for creating this software!!! I couldnt get it to come up in localhost:8080 in chrome running on the pi, and I couldnt get ekos-live to run within Ekos on the pi: it wouldn't accept any credentials I entered. Here is what I hope to do with livestack within my workflow:

I'm not sure ekos-web will work on stellarmate, since they have their own thing going. I built ekos-web to be a standalone version of their local web manager, since I run ubuntu and don't use stellarmate. In the docker-compose file for livestack, try changing the line to something else, like (just don't change the Then |

Alright, try this: Make a copy of your docker-compose.yml file in case there are conflicts. # this will undo any changes you've made to your docker-compose.yml file
git checkout docker-compose.yml
git pull
docker-compose pull nginx
# now update your livestack volumes to be what they need to be in docker-compose.yml
docker-compose up |

Nice. 3-4 seconds per image isn't bad. The lights will likely be longer due to debayering and aligning. |

Yeah, that's all there is for now. I might do up a simple auto-refreshing ui at some point like ekos-web, but at least you can see it. You'll need to refresh manually though. :( |

Thanks again for all the testing on this. It's good to see it working on another system. I've added you as a contributor to the project as recognition. |

cheers! yep, nginx is registering my refresh hits: this is the tail end of the stack process: livestack_1 | INFO:root:done aligning image for ZWO CCD ASI533MC Pro_LIGHT_NGC_884_NONE_30.0_120.0_-15 in 21831.393ms |

Oof. Almost a full minute to do a file. I'll see if I can get that down. Aligning is taking over 20 seconds, and debayering is around 8. And 3 seconds to stretch each channel... Got a ways to go before it is fast. |

I ran a test of livestack running on a pi 4B+ 8Gb with SM OS 1.5.5.
The images are from some initial tests of a new ASI533MC Pro with shots of the Perseus double cluster
taken 2020-12-29 before and after a meridian flip. 10 darks taken with the same gain,
exposure, temperature and offset were placed in the livestack input folder. On startup, livestack created a master dark and I then scp'd 17 (curated previously in ASTAP) lights. For each light, lightstack subtracts the master dark, debayers, aligns, stacks and stretches the resulting stacked image. I ran a Siril script on the same set of dark and light data files for comparison, applied basic background neutralization and photometric color calibration and saved the auto-stretched result.
