In the course of the year I've learned a lot about #astrophotography, and there is no greater manifestation of that development than M31, or the Andromeda Galaxy. I'm so proud of this image, it's what I set out to do when I started this whole journey.
Taken: July 27-31, 2021

Last year, I picked up my first attempt of trying to capture andromeda. This is what it looked like. I had to find it in the sky, and without a tracker, shoot it quick enough so it didn't look streaky.
This is one shot, 1.3 seconds at ISO 3200 via Nikon.

I then learned about stacking, and was able to work really hard (without a tracker), taking 800 of those pictures to stack, to produce what (at the time) was just incredible to me: a close up of a galaxy from the ground.

I was able to get a star-tracker, which allowed me to use less ISO and more exposure time. This led to a substantially better picture, and I was well on my way to figuring out what I needed to do this whole #Astrophotography thing.

As I worked on learning how to keep focus, track with a guiding camera/scope, and my post-processing skills, I was able to get more and more out of this galaxy.

By November of 2020, I was pushing my Nikon setup + Tamron lens to the limit, but I was also getting excellent results!

And now I'm at a point where I can not only get the galaxy, but even zoom into the core and show you the incredible dust trail...

I definitely needed something to get me through the pandemic, and I'm so glad I found something that combined my love of space (galaxies, planets, and nebulae), science (physics of light, stellar compositions), and photography.

Talking to kids when they're struggling🧵
For parents (or anyone who cares for kids!)
It can be really scary to notice something in your kid & be worried suicidality/self-harm.
How do you approach kids?
I've had this conversation >10000 times so I have some tips!
Be CALM
/1
CALM is a memory-trick to remember the key concepts of communicating to a struggling kid but also to remind you to be in control of your own emotions. If you are prepared, you will defeat your initial instinct, which will be to FREAK THE BLEEP OUT!
/2
First, COOPERATE!
You & your kid are a team, and you have a common goal: their present & future wellbeing. Don't set yourself up as the security guard, jailor, punisher, or antagonist. Don't push. Don't pull. Be alongside them, tell them you're willing to walk with them.
A recent study looking at >2M Americans presenting to ERs with MH concern shows the difficulty of "predicting suicide" - we can't predict suicide to help guide important clinical decisions.
The problem: Sensitivity vs PPV
/1
They used machine learning EMR-coded variables (outpatient visits, medications, previous appointments, age, etc etc) - you can see the entire dictionary used to "predict" here (word doc):
They had 2,069,170 ER visits and 899 suicides within 90 days.
After running the model and letting machine learning do its thing, the best fit had the following predictive properties at the 95% percentile cutoff of risk:
Debunking Antivaxxer Tropes:
"Antivaxxer is a slur" 🧵
Many many many accuse me of using a "slur" when I say "antivaxxer". It is a twitter shorthand for sure, but it is not a "slur", and I use it without regret or remorse.
/1
I certainly believe that if one is an "anti-vaxxer", they are not using science, reason, or reality to understand vaccines.
& I note a distrubing trend in antivax and some concerning other beliefs.
That being said, when I say antivax, I only mean "antivaccine belief holder"
/2
Check out my "antivax misinfo" threads. Someday take a look at the "hidden replies" & note that the antivax profiles are quite.. well.. recognizable.
Note: Do not assume every "Antivaxxer" is, I just notice the trend. As do many of my colleagues here space fighting misinfo.
Debunking Antivaxxer Myths
"🇪🇺 Vaxxed Countries have higher mortality"
No, they don't.
This is COMPLEX:
a) countries had different PRE-VACCINE infection (offers more dangerous protection than vax but indeed protection). Obv, vaccination NOT correlated with pre-vax death.
/1
b) The FIRST VACCINATION SERIES against OG COVID was phenomenally effective at preventing infection, transmission, illness, hospitalization, and death (VE >80-90% in all).
This is clearly evident by one of the most striking correlations you'll see!
COVID deaths vs Vax:
/2
And because COVID was the primary driver of excess mortality in 2021, excess ALL CAUSE mortality was almost identical to COVID MORTALITY.
He presents data to scare people into believing that vaccines have caused harm, & he continuously is on the bandwagon that C19 vaccines cause cancer. This is contrary to the damage.
Here, he's using a report using 1998-2019 data.
/1
In fact, there was such a DROP in incidence (assumed to be due to lack of access to health care) in 2020, that they had to amputate the model at 1998-2019 so that it wouldn't project a decrease! (a reasonable thing to do!)
/2
In their report, they clearly show that their trending is based off of models that ONLY end at 2019. ZERO PERCENT of this report is suggesting, implying, or reporting that vaccines have led to an increase in cancers.
He will have a huge platform & can say what ever he wants as long as there is right wing grift.
He is a licensed professional being held standard.
/1
It is against his license to publicly suggest to die by suicide.
It is against his license to publicly & intentionally call physicians 'criminals,' people "not beautiful" or "appalling self-righteous moralizing things."
His license prohibits misgender people intentionally.
/2
The standards of his college are publicly available; including social media. By being licensed, he represents his college and the profession, and that college/profession gets to have a say in how they are represented.
