I know that its the wrong time of year to shoot andromeda, id be better off doing it at the end of the year, but i just got a tracker and this was my first target tracked. only got 23 mins before the clouds came in. was wondering if someone could help me get as much out of it as possible

https://drive.google.com/drive/folders/1Iqhxlo6X4W1muZ15wyA9K2UGKb5tFOXP?usp=share_link

there are the RAW files and the stacked image in there, i included the RAW because there was some weird stacking thing ive never seen before where my TIFF image was all white rather than all black

attached is the image ive been able to get so far

I stacked your light frames with dss.
So your data is ok, don't know about darks and bias frames.
Could be that some settings have been changed in your stacking software.
If you are using sequator I would advise you to switch to dss.

i do use DSS, i did another restack and got the same result, this is the TIFF i get back from DSS after a full stack

Did you only stack the light frames? or all of em

crude latch Apr 13, 2023, 4:38 PM

#

all of them

#

its just like the histogram is at the other end of the graph, all the data is condensed into the brighter pixels rather than the darker

You could test only with light frames. Then you would know if your calibration frames are the issue or the dss itself is acting up.
Im guessing the dss is doing something weird. If I was you I would just reinstall it and try again

#

ill try just a light frame stack, if it still happens then ill install again

#

i dont think ive got the new update so it might even be that, but i dont know why seeing as it isnt discontinued

#

Yeah when something in stacking goes wrong I can never find out exactly what happend, good luck with it

#

update, just did a light frame stack, still came back white

midnight pelican Apr 13, 2023, 4:42 PM

#

Aight reinstalling it is then

#

midnight pelican Aight reinstalling it is then

Still came back white, idk what it could be, doesn't affect the end result anyway so I don't think it's a big issue

#

Did a re edit anyway

I dont know what could be happening but atleast the data is ok.
Might wanna dig thru forums to find more info, most likely it's a setting that needs to be changed.

#

The thing is I haven't changed any settings, and it has never done it before

midnight pelican Apr 13, 2023, 5:24 PM

#

So odd, the stack I downloaded from your drive was very bright for me as well
