Ran a few hours of subs for detecting muon strikes. Got quite a lot.
Asi533mc at -15c, 300s subs maximum stacked median subtracted.

I didnt know you can see muon strikes 
I guess you learn something new every day
broken canopy
so what do u point at to detect these?
Anything. They are always present. At all times of day. I just had my camera set on my kitchen bench while I had lunch.
broken canopy
Yeah. Lower the dark current the better
broken canopy
Yeah. After cosmic rays break up they form
They are super weird. And proof of general relativity. They shouldn’t exist. But they do.

what the hell? u can prove relativity with a dslr is crazy

Holt shit this is amazing

What would cause those lines?
Muons stricking at an angle?
broken canopy
Yes, going through multiple pixels at an angle.
floral ledge
what angle do you position the camera at
so that you can get a long line but also a feasible chance at catching a muon

Swear I had lines similar to that in my andromeda data that i scrapped the frames cuz I was like wtf are those @broken canopy
solid pendant
didn't think of that when i blinked them
broken canopy
what angle do you position the camera at
Doesn’t matter. Technically 45 I guess.
The majority will come straight in.
floral ledge
also if u stack the exposures, doesnt it average out the muon trails?
how do u get it to show up in a stack
broken canopy
That’s why you maximum stack
floral ledge
oh whats that
broken canopy
Then median subtract, but that’s less important
Instead of averaging the pixels it only records the maximum each pixel had.
floral ledge
ohh i see
medium subtract makes it easier to see right?
because background will be clipped
also i saw a small blue line in one of my 120s darks
is that possibly a muon

Subtracts the dead pixels and some hot pixels. As they aren’t random and don’t change.
broken canopy
is that possibly a muon
Quite possibly

wait are dead pixels and hot pixels different?
broken canopy
Yea
Dead pixels are dead. They never come back.
Hot pixels are just pixels that will be stuck on for a little while. Cold pixels are pixels that don’t get activated easily
floral ledge
ohh i always thought they were the same thing
broken canopy
Yeah hot pixels are temperature based
The higher the temperature, the easier it is for current to leak in to a particular pixel
broken canopy
Its pretty fun yeah. I’ll be doing another run today.
Hoping for that ever elusive shower

do the rates correspond with CMEs and solar activity?
broken canopy
do the rates correspond with CMEs and solar activity?
nah comsic rays come from everywhere, mainly other galaxies.
and other black holes
there may be slightly more during high solar activity, but you wont notice it.
floral ledge
nah comsic rays come from everywhere, mainly other galaxies.
oh rly?
broken canopy
cosmic rays are there during the night too
broken canopy
would this be a muon strike? <@384553833268903948>
yes that is one

Nice to know thanks 👍
