Stroke of cosmic luck this morning with a satellite transit of Saturn's rings. 30 frames played back at 0.1x realtime.
ASI462MM at 8100mm, RG610 filter, 10ms @ 100fps.
#Satellite - Saturn Transit

You’re resolving satellite detail wtf
long tangle
I would love a website to calculate ISS transit on planets

Wow. Thanks!
deep lily
have you identified it yet?
kindred olive
have you identified it yet?
Nope
But only looked through Starlink V2s as it has two solar arrays. Might be a different satellite all together
not sure

Yeah its very unlikely that this is a v2 mini
Its waay to bright for that
kindred olive
Yeah its very unlikely that this is a v2 mini
Its waay to bright for that
I mean I was at 10msec 500 gain
Saturn is dim
I’d estimate it was about mag 7 comparing to Saturn’s moons
I’ve upped the gamma massively for the gif btw so the dimmer stuff shows better
deep lily
I mean I was at 10msec 500 gain
https://www.astrobin.com/rgt0ez/D/
this is:
Shutter=34.30ms
Gain=5000 (100%)
best 10/100 frames stacked
So these things are really dim
the entire image width there is 21" btw
kindred olive
Uranus gain setting only goes to 600
But regardless to be the same surface brightness as Saturn puts it around mag 7-8
Which is in the right range
Unless you’ve measured it to be a different brightness?
deep lily
Uranus gain setting only goes to 600
yeah the max for my cam is 5000
But 100% is still 100% regardless of the gain range
kindred olive
Yeah I’m at 83% then. Not far off.
And I did need to boost the exposure to see it in post processing
Barely there in linear

But regardless to be the same surface brightness as Saturn puts it around mag 7-...
i mean yeah v2 minis are more or less mag. 7 when deployed
deep lily
And I did need to boost the exposure to see it in post processing
yeah then maybe it was the right brightness
What did you use to check btw?
kindred olive
Just stellarium. I haven’t checked the newer launches as they aren’t included for a while I don’t think

ah ok
SkyTrack can identify
You can also use HeavenSat with a full catalouge from the night
kindred olive
Also, just calculated Saturn surface brightness as +6.6/arcsec^2
which puts the sat almost exactly on mag 6-8 range
deep lily
which puts the sat almost exactly on mag 6-8 range
the surface mag or total?
kindred olive
total, although it spans about 1-2" anyway so won't be far off the 6.6. Given it's dimmer slightly, then +7
raw tiff
linear
deep lily
yeah might be a starlink then
but check with a proper program to be sure
kindred olive
yup
kindred olive
will do
