Introduction to Real Time Astro Imaging (EAA)
มุมมอง 4352 หลายเดือนก่อน
Real Time Astro Imaging, sometimes called Electronically Assisted Astronomy ("EAA"), is the practice of using astrophotography hardware and software to observe celestial objects. Unlike conventional astrophotography, images are visible immediately, and improve as the observer continues to capture additional images and "live stacks" them on top of prior captures. The practice allows faint deep s...

Telescopes 101: Part 1 - Collimating your laser collimator
มุมมอง 396 หลายเดือนก่อน
In part 1 of our Telescopes 101 presentation from January of 2024, MHAA President Jack Chastain talks about collimating your laser collimator. You can use a laser collimator to collimate a Newtonian scope, i.e. align its mirrors with each other and the eyepiece in your focuser. But first, to make sure the laser will do that accurately you should make sure the laser itself is collimated, i.e. ma...

It's awesome to hear Joe Rao 😊❤
Very cool!😊
Sorry, woke shit has no place in society.
My pronouns are I, you, he, she, it, we, they, me, him, her, us and them. Clowns.
I was looking forward to watching this, unfortunately current day gender politics raises its ugly head from the outset. I'm out.
The authors listing their pronouns? Really? Don't they want people to take them seriously?

That’s funny

Very informative! I have dabbled a bit using and SDR and an outdoor FM antenna for meteor detection. Also got a Nooelec small parabolic dish and the Sawbird H1 LNA and hydrogen line filter. That isn't set up yet but you got me a lot closer with the Radio SkyPipe idea. There is also a Radio Sky Spectrograph and bridge software that is compatible with the rtl_tcp program i want to use on an R Pi. Fun stuff to experiment with, thanks for the video
The foldable "cheat sheet" that I mentioned at the beginning, and that I used to organize this presentation, is available at www.spy-hill.net/~myers/astro/stellarium/StellariumVadeMecum.pdf
Thank you for this lecture. I knew nothing about this before, but it was still accessible to my level and I learned a lot
I gotta say, I really like your style. Your seem laidback and easy going. If the teachers had been laidback when I was in school I might have learned something.. 😅😅. I'm dyslexic with numbers proper name is dyscalulia. Made it hard to learn much, and they didn't really know much about it way back then. I had to do 4th grade twice..lol.,👋✌☝️😁
Thank you.
Thanks, guys and gals. I am 68 and retired and while some may say I have too many hobbies radio telescopes are a good fit for one of my hobbies which is amature radio. Hence, I do expect to give this form of observing what's beyond our blue dot a go. Like many, I assumed it took a lot of expensive equipment to have an effective tool & indeed it does not.....
Absolutely correct, especially with how good and how cheap technology has gotten in the past 20 years. I strongly suggest reaching out to your local astronomy related hobby groups and associations to find some peers, as well. Peers in these very technical hobbies can accelerate your growth and reduce potential frustrations a ton!
I've always wondered how they "know" these facts about these celestial bodies just by sight alone. They state things as if someone has been there and can say for certain it's true when they can't even send a space craft because the radiation is so strong that it causes interference with electronics that guide the ship.
@keltonfoster That's a very big question, but one I always like to learn about myself when I hear about new discoveries. Science is always an evolving set of knowledge, especially on frontiers like our understanding of planetary moons. One of the exciting things about it is that everything we learn can be refined and even if we had the right idea from the start we can usually improve our understanding to a finer resolution or degree with more data. But, just because a physical entity like a space craft can't get near something, doesn't mean information about that object isn't reaching us in numerous other ways. That's usually because energy that might be harmful, like the type of radiation you refer to that can damage or interfere with electronics, does not necessarily interfere with the type of energy at other points on the spectrum that carry other information. As an example, consider that until recently we couldn't get particularly close to the sun, but we still learned quite a bit about it from a distance. Some of it was from direct observation at that distance while other information was gleaned by inference where known data implies something to be likely even though we need to collect more observations to confirm it, etc. With the Parker Solar Probe we finally sent a craft that actually gets so close that it touches the Sun's upper atmosphere (corona). From that we've learned new information as well as refined old models and understandings. When it comes to things outside of our solar system like exoplanet and other stars, much of that information is uncovered by observing the behavior of the physical body and the light from/near it. ie we can get an idea of the chemical composition of an exoplanet's atmosphere by using spectography to see it's absorption lines, it's spin by looking at red shift on either side of the planet, it's size by its orbit etc. None of that requires close proximity, given high enough resolution of the data with our long range observatories. These are all fascinating facets of astronomy and astrophysics to read more about online. Thanks for watching our channel!
Hey Phoebe!
interesting. thanks.
wow people need to watch this video? Most people just want a backyard good-to-go SDR radio telescope kit learning course to get started without going to garage sales. 😎 thanks.
nice lecture.
Have you had the chance to view Lunt's LS300T....?
Hi, i want to upgrade my pst to a 60mm alpha H scope. Which scope would be a great upgrade for visual use? ( my Guess is That the sm 70 111 show better promences, while the lunt 60 MT, better surface detail?) Thanks for the tip!
Very thorough. Good presentation. Thank you.
