Advanced #astrophotography!!
=-=-=-=-=-=-=-=-=-=-=-=

Within the Cygnus constellation lies the bright star Sadr, and surrounding it is the Gamma Cygni Nebula and the Crescent Nebula (NGC 6888). By making a mosaic (3 images stitched), I was able to capture them all!

As it's a mosaic, the image is HUGE (10,000 pixels by 6,000 pixels), so I can show individual regions. This is the Crescent Nebula. A central star is in its last stages of life, so it is blowing out winds of up to 5.4mil km/hr. It looks a lot like a brain :) #psychtwitter

The Gamma Cygni Nebula (also called the Sadr Region). The large star Sadr is about 2000 LY away and is about 150 times larger than our sun. The nebula surrounding it is about 3000 LY behind Sadr.

This entire project took a ton of planning, and learning many new techniques both in processing as well as the photography portion. It represents 22 hours of imaging over the course of 14 days, and almost 2 full days of processing techniques!

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
/1 The Andromeda Galaxy
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.

Just booed & thumbsdowned a parade of antivaxxers in Vancouver. They were as kind and civil as you would imagine 😜
To be fair I'm dressed like this so I gave them a lot to work with. Image
Here's the crust of what they shouted at me:

1) "what are you afraid of?"

A. People dying needlessly to a preventable disease where common infection techniques like vaccination and mitigation work.

REFLECTIVE LISTENING Mini🧵
=-=-=-=-=-=-=-=-=-=-=
Quick #meded / #psychtwitter teaching

"We need to listen to our patients," right? But *HOW* we listen matters! Many annoyingly *parrot*, which makes the person feel UNHEARD.

This is called "reflecting" and it is ANNOYING AF.
/1
"I feel angry."
"It sounds like you feel angry."

"My wife left me."
"So you're telling me your wife left you."

It's really really really annoying.

There are good and easy modifications that REQUIRE THOUGHT AND EFFORT but both demonstrate to the patient that you've heard them, but also advance the conversation and allow the patient to think/reframe what they are saying.

Let's look at the statement.

Except that these published/preliminary findings do NOT show the impact of loss of in-person school. They cannot, because they were not designed to do so. They show that during a worldwide pandemic that killed hundreds of thousands, kids suffered too.
BC, which has had in-person schooling since September, experienced similar patterns and there has been NO correlation between "returning to school" and anything other than "increased stress on kids."

School is an additional stress. Let's all work to make that stress minimal.
And keeping with the archaic belief system out of Sick Kids pediatricians, they continue to slam "media use" in kids as some kind of boogieman. The science world is leaving them behind.

Not only is this imposter (he is not currently a health care employee, I'm told) unfunny and a horrible representative, he's just plain wrong. Medical students spend 2 full years working in hospitals learning from supervisors prior to becoming interns.
Plus, there is NO evidence of a "july" effect. This video is precisely the type of myth that an awful, uneducated, stigmatizing asshole would spout.

Interns (graduated medical students in the first year) are carefully supervised by junior residents, senior residents, and staff physicians, as they SUPERVISE medical students and teach them. They are highly skilled, conscientous, and hard-working.
