Hydrogen Alpha filter lens photos of the sun : theCHIVE

: Alan Friedman works full time as a greeting card designer but has a passion for astronomy. He captures brilliant photos of the sun using a small telescope and Hydrogen Alpha filter which acts as a lens and streams images in the same way as a webcam would. Each photo is made out of thousands of frames of images that are then combined and adjusted in color and tonality to create a final high res photograph.

#7 Yeah, small telescope. Looks cheap. Ill just stop by this afternoon on my way home from work and pick one of these up with my change from the gas station.

hmm

yeah haha, that's a Schmidt -Cassegrain scope on a "go to" gps mount. That and the sun filters wold set you back at least $3k-$4k. i mean it is small though, in the world of super powerful telescopes haha

At least. My guess was in the $ 6-10 K range.
Also, the hydrogen alpha filter is not a "lens" in any useful sense. It's designed to strip out all light except that pure single color (Balmer alpha, in the red at 656.281 nm) coming from a particular electron transition in hydrogen. The pics are showing the details of the solar "photosphere" surface at roughly 5800 kelvins. The convection cells ("granules") are what causes that orange-peel look.

huh?

I don't understand any of what I just read, but uhm.. cool!
hmm

yeah that "at least" was for a bottom end Cassegrain scope. they can reach upwards of $10k

Probably one of the coolest things I've seen in a while. Astronomy just reinforces how much I don't want to live on this planet anymore.

This series made you want to live on the Sun perhaps?

Your cunning plan…may have a small flaw.

The sun is my favorite planet 'cause it's like the king of the planets.

The moon is not made of green cheese. But what if it was made of spare ribs, would ya eat it then?

I wanted to look through this post, but I don't want to go blind.

The extreme close-up of the sun in #7 is pretty cool. Looks almost like earth

#4 That's pretty damn awesome

I actually love theoretical physics and have been trying learning everything about it that I can. (I'm very sad I never got a chance to do the QM series at my university before I graduated) If I had more free time, I'd go buy some textbooks and teach myself… everything. But in the mean time, I'd gladly settle for a chat about the orbits and energy states of electrons. Do you have any knowledge pertaining to how each energy level's orbit is shaped the way it is? Some of the representation of the orbits that I've seen are very complicated (far from an ellipse, with multiple disjointed segments).

You can get into basic astronomy for very little money. Even a 4.5" telescope can resolve the clouds and moons of Jupiter, the rings of Saturn, and some amazing views of the moon. I'll never forget my old landlord years ago telling me to look into the telescope he had set up and watching Saturn glide into view. I've since shared that experience with so many people with my own scope and its the one thing they have never forgotten.
