You boys with your fancy CCD and CMOS cameras have it so easy. 😉 I personally miss my days working in a darkroom processing glass plates and film. After hours of manually guiding the scope, there was something extra special in watching the image appear while the plate was in the developer bath. And then there was the mind numbing experience of using a densitometer to manually measure the brightness of hundreds of stars. Clear skies to all.
Thing that got me hooked on AP was that last comet. Drove up a hill at midnight. Got out the car. Looked around for 5 min. "I think that smudge is it. Is that it? I think that might be it." Took a 30 sec shot with my entry level $500 (including 2 lenses and a bag) Canon DSLR. I wasn't even sure if it was in shot. Looked at the display on the back of the camera and it looked like a firework had gone off across the sky. Wow! OK now I get it.
I knew it was going to happen when I bought my first telescope just one year ago. I now have 3, the largest is 208mm and I’ve ordered all the parts to add a camera - going inexpensive, build some skill, then see what happens next. Thanks for your channel Dylan, it’s better than Mayberry RFD re-runs, and I learn stuff.
Can't disagree with any of what you said, astrophotography is superior to visual. But that visual can be relaxing as hell, and sometimes an entire night of astrophotography is just swearing loudly and waking up your neighbors at 3am. Those good nights though are worth it all.
I just picked up this hobby a few weeks ago. Last night I took out a pair of binoculars and trudged through the freshly fallen snow on my deck and stared up at the crystal clear sky. The air was super crisp and it's amazing how much the naked eye misses. I can't wait for summer but I've read that the humidity affects seeing.
@@Astronurd I'm not sure I know what your point is. Are you saying that visual astronomy doesn't include binoculars or the unaided eye? Because visual astronomy predates the invention of the telescope.
@@spamcan9208 Yes i know this, but what Dylan is always referring to is the astronomers who use their telescopes visually. He constantly derides us that do. I myself have two pairs of binoculars. A Pentax 20x60 WP and Opticron 15x70’s. I use these in rotation with my three telescopes.
@3:50 .... The parallax of Alpha Centauri was successfully measured from Cape Town, South Africa by Thomas Henderson using a mural circle. Bessel and Von Struve also made use of other instruments other than photography to measure their first parallaxes in the 1830's So it is possible to measure parallax without using a camera.
The Second American Revolution doesn't kick off until 2025, this is the opening shots. It's going to get a LOT worse in the next four years. Between the spiders, the jellyfish and dying in the desert from either not having enough water, or foolishly sticking your hand down a wombat hole, Australia is looking better all the time, except no guns, and that's a real negative for me.
At 5:17 you talk about persistence. I think if you have dedicated astro cameras or still visual we all share that persistence. Although when I have to drag my rig outside my persistence is tested 😂. Love you vids Dylan, keep em coming!
The pan out to your wife playing the violin while you gaze introspectively out at the hail storm was great. Comedy and cinematography all in one. Well done. Also, thanks for the astrophotography history lesson. You mentioned Harvard but do you feel the work of Brian Schmidt and his team have done in proving the universe is accelerating played any part in the development of better and larger telescopes and the cameras they used while hunting for supernovae, there by impacting astrophotography?
It's an amazing time to be around and see the progress..I have a few astronomy photo books from the early 70s (and one Astro book from 1860s by John Herschel) and to see what they did back then was amazing with film
My plan is to buy all of the high-ticket astrophotography gear before I settle down. Hopefully that means a Losmandy mount and/or C11 by the end of the 2021. I like my EQ6-R Pro but I just don't think it's up to the task of long-exposure imaging w/ an SCT. In the mean time, I've switched-gears to wide-field on a Esprit ED100. My only issue, is when I order something that is said to be "in stock" but still end up waiting MONTHS for it to ship. As a result, I'm relegated to using a filter slider while I wait for the 11-slot filter wheel to arrive. Probably still waiting for it to be manufactured.
Thanks for another video Dylan. Watching your videos sometimes is just way more entertaining then reading Cloudy Nights, and seeing how people bash each other on what gear is better.
Great video, Dylan! Love the violin part!! Very fitting of these (cloudy and rainy) times were living. In the meantime, it doesnt hurt learning about the history of astrophotography
Love it mate! Great vid as usual. Biggest questions I get tho are for getting a DSLR working with a Reflector...... maybe a vid on the pros and cons over a Reflector vs Smidt for photography. (would like to know myself as I am considering upgrading to a Smidt)
Thanks for the video man getting into astrophotography is very overwhelming it's easy to worry everything I'm doing is wrong hopefully you continue with this type of video I will watch every second .
Nice approach; History of Astrophotography & How to put camera on telescope. Basic but still entertaining. And this is the perfect distraction from what is going on in US. Stay Safe Dylan Don’t ever lose your sense of humor!!
Good to see your rain! Nice and fresh. Bad for astronomy, sure. But isn't it nice anyway! And good speech too. We've pretty much always had a camera on telescopes for anything useful. But I do like to just visually observe, just for the awe of it.
Great video! Just remember to balance your instrument after you attach a camera. It helps prevent the drive motors, from over working. Awesome video as always!
Jeez, even the hail tries to kill you in Australia. We only get hail that big when there's a decently sized tornado around... And we're at the edge of tornado alley.... The violin bit was hilarious too.
The history of astronomy and astrophotography is very interesting. I didn't know that what was (for 70+ years) the worlds biggest telescope was in Ireland. I used to think I lived in a boring place. Sadly I can't visit it because of lockdown, but hopefully soon I get a chance. Very interesting video as usual:)
Thank you for getting to the basics. What do you think about using filters or filter wheels in your photography? I need more basics like this as a novice.
Sounds like my history. LOL I started out at age 9 or 10 with a Tasco 50mm but never did much astrophotography until those handy dandy smart phones came around. When I retired, I bought myself a 10" Dob and enjoyed visual mucho better and the occasional short phone photo. One year into that, I got an 80mm refractor on a tracking mount and with stop watch in hand, tried out my old Nikon D40. After the initial 120 second wait time (exposure), the image of M42 was jaw-dropping (and the hook went into my lip). Now, a few thousand $$$ later, I enjoy the challenge of astrophotography and love to set up both scopes and visual the time away while the photo rig snaps away.
Great video Dylan, just one point of order though. The observed change in position of the stars during the eclipse was a confirmation of Einstein's theory of General (not special) relativity. Cheers

@@DylanODonnell Wow! It will knock off a lot of small shrubs! sometimes here in North Texas, we get baseball size hail. We have to replace our roofs if that happens
Somebody needs to do the history of amateur astrophotography, I was around doing it starting in the 70’s up to around the early mid 90’s with hyper sensitized film, there is quite a rich and interesting history from the amateur side too.

Hey Dylan, you and Trevor from astrobackyard inspired me into the astrophotography world. Since i fell in love with it im planning on buying a astrophotography equipment. What im thinking to buy is: Skywatcher EQ5 pro for mount, a skywatcher 150/750 f5 telescope, a small guide scope, and a autoguiding cam, all of these would cost me about 1200-1300 dollars. I already have a dslr and a laptop so i don't need to buy them. Do you think these equipment would give me good and sharp images of nebulae and galaxies with 1-8 hours of exposure depending on what object? And if any suggestions on what part of the equipment i should change please let me know and please don't recommend expensive equipments because i cant afford them.
From the most likely accurate historical evidence depicted at 2:50, we can safely say that Galileo was better at drawing p*****s, than drawing accurate star/lunar charts...
g`day dylan i guess when you only have a candle to see what your drawing in the middle of the night you can be out by a bit and a 1/2 lol i think old galileo did ok with what he had to work with back then ....great video dylan i enjoyed the history lesson would like to read the rest of your essay of which the video is a summary of .... you should get your trouble and strife (the wife) to play more on your videos i remember the carpark (i think you were in a carpark) video when she last played violin on your video ... great work misses o`donnell cheers james D
Hi Dylan, My school is currently applying for an ICT innovation fund from the Hong Kong government that needs to focus on future ready learning outcomes like Ai, Big Data, IoT etc. We are planning to build an automated observatory but to be eligible for the funding we need to connect the dots in regards to how the students will use the data from the Telescope to better understand future ready technologies. They have asked for specific softwares which I have considered Tensorflow and other API's but being a novice in this field I would love your help or feedback on which direction to take!
100% Facts Astrophotography is a black hole money goes in an pretty photos are ejected "with a lot of work an practice".... In my 2nd year of astrophotography an I have already well crossed the 5 figure mark. But Dylan if we could go back an make the decision all over again "not how the space time continuum works" I would still have made the same choice maybe not the same 1st scope. However I defiantly love Astrophotography as well as sharing the results. Seeing a person's eyes light up when you show them a compressed an scaled jpg on your phone of any of your captures is priceless. Sure everything is meaningless an we are all going to die, But while we are alive in our current state we have a purpose an our hobby is a very humbling and inspiring one.
Hi Dylan Just getting started with this hobby. Bought a Star Adventurer pro pack, but am having real difficulties polar aligning it. I'm in Lismore, so not too far from you, but when I try to find the small group of stars for the alignment, I just can't see them. Not naked eye or with the polar scope. Spent last night starring at the Southern Celestial Pole (thanks to Stellarium) for over an hour. Please help. Do you have any advise for a complete idiot😁 trying to align this dam thing? Cheers
Galileo was awesome. Let's not forget that. But, he was sauced when he drew star fields (not that there is anything wrong with that). Fact. Why? Because you read it here.

Ha, who would have thought astronomers had a funny bone. Thank you Dylan good background to a number of interesting astrophotography histories. I've enrolled in a gym membership to flex up.. And emptying children's coin collections and piggybanks
Special relativity does not deal with gravitation but rather object moving at a constant velocity. It was/is the theory of General Relativity which describes gravity (in terms of the geometry of space time) and hence made the prediction regarding the deflection of photons passing near a massive object (to be complete, Newtonian Gravity also predicts a deflection but with about half the value of that predicted by Relativity) . Suggest you read a little more history of astronomy (eg., "The Sleep Walkers") to see how visual astronomy, without even telescopes, was crucial to the development of modern physics - Brahe -> Kepler -> Newton ...
You boys with your fancy CCD and CMOS cameras have it so easy. 😉

It was/is the theory of General Relativity which describes gravity (in terms of the geometry of space time) and hence made the prediction regarding the deflection of photons passing near a massive object (to be complete, Newtonian Gravity also predicts a deflection but with about half the value of that predicted by Relativity) .
Suggest you read a little more history of astronomy (eg., "The Sleep Walkers") to see how visual astronomy, without even telescopes, was crucial to the development of modern physics - Brahe -> Kepler -> Newton ...
