Stabilized 4K Footage of ISS from my Telescope!

That came out nicely, Astro.
I could be wrong looking at a small image but it looks like you went with the "didn't stack" option.
(Expecting a quick... "Yeah, I did stack...")
In any event, as others have said, this ain't easy and without your software and expertise would be impossible.

5 stars.

Great to see you posting again!! Five stars for the good work!

The camera is shooting from an altitude azimuth perspective. The space station is therefore exhibiting normal field rotation. To avoid that I would have to align the telescope perpendicular to the plane of the space station's orbit. Instead I align it relative to the horizon. It's no different than watching a plane coming up over the horizon, crossing overhead, and appearing to turn as it goes towards the opposite horizon in the distance. The plane doesn't have to turn at all for it to look like it's turning relative to your position.

This is minde boggling

Who knew it’s all just one giant puppet show for the masses

You're correct, I went with the didn't stack version after surveying a few people about which looked the best. I included a link to the stacked version in a pinned comment on the video though, so kind of a best of both worlds option.

You proved it is fake yourself. You can’t talk your way out of this. The space station can not be visible at night. At most a light source from the space station could be visible but you would not be able to see the actual space station. If you had a light source of say 100,000 lumens you could see the light source but you would not be able to see the ISS behind the light source.

You're completely wrong. Yes the space station can be visible at night, as long as it has line of sight to the sun. And yes it can have that from 400 km altitude.

Yes sir, nice!!!!! The 8" LX200 would be a Schmidt right? And thanks for your contribution on here, love the work you do!!!!!

an ak-47 bullet leaves the gun at 1500 mph

this thing is traveling 18,000 mph

try tracking a bullet with your telescope. and keeping it in the middle of the view.

surprised the military isn't knocking on your door, plenty of countries would like to have that ability

if you can track that you can track an f-35 going 1,200 mph at 60,000 feet(5 miles) and shoot it down

don't sell out!!

Yes, it's a Schmidt.

july is hardest time to view right, all the humidity depending on where you are.

January is least humid right, and the higher the elevation the better

you gotta get out of the city to see something like that i thought, all the light pollution

National Aeronautics' first director was a former Hollywood
studio manager - not a man of science or rocket technology

You mean space garbage, compared with galactic history and what has been created and used during the exploration of existence.
I've had recalls of previous lives before this devolved meat suit zoo, you haven't seen space craft or space stations yet.

Prove it, as you said mathematically, I’ll wait. oh and thanks for banning that IP address. You can’t win this argument and you know it so you resorted to the fact you are a forum admin to ban an IP to shut down the conversation.

Also false, I haven't banned anyone on this thread. I'm not the only mod here and you are not entitled to know who banned who.

You all know he is filming this from our donations, LMFAO

You realize I've had this telescope for 17 years, right? I used a stimulus check to buy the Blackmagic Camera, so no, I didn't even need any of my YouTube money to film this.

It looks fake because it's real!

Well, yes. Reality doesn't care about your preconceived notions. When it violates those preconceptions, the problem is with you, not reality.

Huge helium balloons hold that up. It's just going in a big circle with the wind

Here you go. Midway through the pass, ISS was at a latitude of 25.5557 degrees N, a longitude of 84.153 degrees W and an altitude of 419,812 m.

Using my moon and sun calculations spreadsheet ( [link to drive.google.com (secure)] ) I found that the sun should have been 15.17 degrees below the astronomical horizon (a plane 90 degrees from the zenith) as seen from ISS at that time:
[link to drive.google.com (secure)]
But now the critical question, how far below the astronomical horizon is the limb of the earth as seen from ISS? In other words, how much does the horizon dip as seen from ISS? First we calculate the distance to the horizon from the altitude of ISS:
d = sqrt(h*(2*r+h))
sqrt(400*(2*6371+400)) = 2292.77 km
Now we calculate the dip:
tan(dip) = d/r
atan(2292.77/6371) = 19.79 degrees
19.79 degrees > 15.17 degrees, therefore the sun is above the horizon as I am tracking it. Oh and that's even assuming it's about 20 km lower than it actually was.

I feel privileged bring able to see these videos. I expect that there's not very many people in the world that can do this. 5*

it's astonishing, total respect for what you do and share

Awesome dude

@ 3:34. Is that rocket fuel burning at the bottom?

Not sure what you're referring to? The white thing at the bottom of the station is the Dragon capsule.

I didn't steal anything you retard. I've had this scope for 17 years you fucking idiot.
