DSS 4.2.2 what is that dots?

[miki63au]

Hello everyone,


Puzzled by this line of dots after the DSS run. Looks like all the same patern in different locations. Not seen in the subs.


Is my DSS has a bad setting somewhere I'm not aware of?


Thanks for any help.

They look like hot pixels not getting properly removed by your darks, combined with movement between frames.


I had a similar issue with hot pixels sneaking through in Astro Pixel processor when I was using a drizzle process and you could clearly see my dithering pattern in them, little square spirals instead of a line of dots in my case.

Ah, tnx Paul.... I had no darks. Assumed the 314L+ @ -15C not need one.
Oooppppsss :rolleyes:


Thank you,

Just do some now with the same settings and give a repro a go

Any sensor will have some hot pixels, which is not to say that they will be visibly "hot" in an unstretched image. it does not mean that the pixel will be at max value (though some might be) just that they will not be as linear as most. If you have a handful of pixels which accumulate dark current 10% faster than the average of the sensor then they will likely show up when you stretch the data, even if they were not visible before stretching

A bit better :thumbsup:


Thanks guys :hi:
Just need more clear sky to collect more L, and RGB :D
