Welcome to my channel dedicated to astronomy & photography of the night. I do my best to give hints & tips on photographing the night sky, how to plan Milky Way landscapes, spectacular moonrises & moonsets + anything else loosely related to the subject. I also do reviews on some of the gear that I use.
I had that celestron zoom, it is decent, take the eyecup off of that and it has t threads so basically it acts as a variable eyepiece projection system, but that is really only practical for lunar , solar and digiscoping, or use as an extremely long zoom lens for daytime photography.
F10 is not the aperture, the aperture is 6" regardless of the focal ratio. Stop thinking like a photographer lol, the terms are used differently, apreture refers to actual aperture in a telescope, where a photographer refers to aperture by the f stop set by the diaphragm in the camera lens. And lens in photography refers to what would be the equivalent of the optical tube, a camera lens. Astronomers prefer to not call eyepieces "lenses".
Single lens are not achromat, they a chromats lol. Doublet crown and flint is achromat, doublet Ed is semi apo or apo depending on type of ED glass and focal length. Most triplet Ed and flourite are apo, but in the early days some triplets were semi apo. Flourite doublet and triplets are generally all apos. It irks me when I see people on youtube call singlets achromats. There is no such thing as a singlet that can correct for any level of chromatic abberations, even basic achromat level of correction which leaves only the purple fringe. Singlets were like prisms with a rainbow of abberations
You sound a bit like one of our ex astro society members who was always correcting us about certain terms. He was always right, in his eyes, but none of us particularly liked him.
@starman1969 welcome to the world of aspergers. You will find a bunch in the astro community and yes, they are usually right. And it is a pity that people would rather be wrong and dislike those that are right, but have a direct way of letting you know, rather than just sugar coating everything or sacrificing their principles for the sake of being well liked.
Cool, never knew it was such a large museum. Houston's on my to visit list now! The Air and Space Museum in Washington DC is worh a visit and free. I went in 2010. It had rhe Apollo 11 Command Module and even the (unused) faecal bags from Apollo 11 on display. 😂
Great vlog around the space centre, Most people has seen pictures of the shuttle on top of the Jumbo but not hands on like this vlog, If you would of got closer to the running caterpillar you would of heard it saying oo aa oo aa oo aa this concrete is hot,
The eclipse here in Ohio was the most amazing thing I've ever seen in my life. Everyone reacted like you did in this video, and my mom cried! I felt like I was on another planet!
Hello Steven, would you do a short video on the upcoming explosion of {T Coronae Borealis}??? As you do explain the skies quite gracefully to the not-so-knowledgeable as me.
Nice one, Steve. Glad you managed to go while you were in that neck of the woods. I regularly visit Houston for work and have had a few trips to the JSC in my spare time while it’s nice and quiet; somewhere that you can spend hours. The tours around the Mission Control buildings and test centre are excellent. Thanks for sharing.
Stephen, an absolutely superb video - one of your best. You so know how to get to world class places and make them accessible and interesting. It's a knack you have. Thank you !
I remember seeing a shuttle on the back of a 747 fly over Manchester - apparently orbiter Enterprise (which was a test one) in 1983. Thanks for your US videos, inspiring stuff.
I was off school, sick for some reason , on the 6th June 1983 and approaching lunch time my mother exclaimed from the kitchen 'Come and see this' and ushered me to the back steps as we watched Challenger on the back of a 747 flying low over Glasgow. Less than three years later we watched the disaster over Florida.
The bond film of 1979 moonraker featured a space shuttle on a Boeing 747 , I think it was model though the some of film was shot in outer space. I remember the film well I saw it at the metropole theatre in Blackpool unfortunately the theatre is a nightclub now
Mostly the difference looks to be in camera noise reduction. I always turn that off, but based on this I would take the extra detail in the d850 even at night
Stephen we have just watched your present 🎁 opening video tonight at Chris higgitts and there was a large parcel 📦 for you but you have not got it we left it with Pete at happy dayz they have opened their presents so either it's at Chris or Pete's
For a camera lens a faster F ratio gathers more light but not a telescope. The aperture affects the amount of light that is gathered. A 130mm telescope gathers the same amount of light no matter what the F ratio is. The faster scopes have wider field of views and lower magnifications.
It's interesting how astronomers use different terms for f ratios than photographers. As a photographer going into astronomy, I found it quite hard to adapt.
Wasn't it amazing! We were on a short break in Yorks Dales nr Skipton, I dragged Mrs B out into a field at 10.30 and she was about to go back to the campsite when it started to kick off big style, didn't know where to look!
If you type star man in on RU-vid you don't come up only David Bowie maybe change it to star man uk or something i only found you on a link just a thought enjoyed the videos 😊
One hell of a display wasn't it mate? So glad I had the heads up from Absolute Radio of all places and picked a spot to go to. Never thought I'd get a full arc panorama facing south in the UK! I'm still buzzing now from it!
