Hello all
i m strugglin since a few hours to process the file of job 1196.
i cant find a way to calibrate correctly Lum file .
all the fits of this job are shoot in september so i use the latest calib file .
Here is the result of the integration with WPBB with Lum file and calib file:
We can see lots of dust donut
i try all sort of combination of calib file , corrected flat film by adding some value , it doesnt work
after a while i integrated without any flats :
And here is my flat file used before :
we can see that the big donut low-left , is not exactly at the same place on the flat file than on the integration file.
it is obvious if you switch rapidily between frames in pixinsight.
I think that the cam has rotate since the flat have been shoot or that dust have move .
As it is an open scope , i think that flats have to be taken more more often than one each 6months
Also , with this camera , you should take way longer flat . the LUM flat are 0.02s long exposure. I ve read that on some cmos camera , very short exposure raise problem. I think you should try a dimmer flat planel and have flats shoot with +1s long exposure .
i dont know if somebody have succeeded to deals with L file on this scope but if yes, please share the recipe

Hi
supplementary dataset are allways welcome , but you dont have to do it
It's the fair thing to do from my side however. Syndicates are about working together and that rule applies to us also
I will ask Pete and Phil to collaborate over the next week and add some to the share folder

Please ignore my dylexia wherever possible, just be thankful I can control my Tourettes ;)
Things to do, so little time!

We have a good run of clear skies this next 7/10 days
So if you need to put any jobs back in, then now is the time as we are entering unpredictable weather season time for the next month!
So, it's get it while it's hot weather and not to be missed

I had a quick look at my submitted jobs using LRGB.
1233 - NGC660 is completed but will be affected by the flats problem. However, I notice it has been resubmitted so that is OK.
1106 - M81 is part way through. It should be cancelled and resubmitted unless we can save the RGB data collected so far. In which case I will resubmit without subs we have already collected.
All my other jobs have either, not started, or are narrowband and presumably OK if the Lum flat was the only one affected.
I'll have a look at the narrowband tomorrow, just to check.

hello
i confirm , i processed job 1267 ngc7023, it is awfull , so much dust after calibration .
may be the flat , the dark , i dont know
I think that a new process should be establish for this pier , may be a flat sesionn each weeks and precalibration of data obtain this week ? to prevent such bad dataset ?
