Most of the videos on my channel are related to astronomy, space and satellites, mixed in with photography, time-lapse, hyperlapse, drones, gimbals, etc. You will also find many "how-to"-videos, particularly where I found RU-vid lacked videos on specific topics. Being a steam-train enthusiast who grew up on a railway town, I also uploaded a few steam/train videos. Watch my 10-year celebration video for an overview. Enjoy!
Thank you so much. It warms my heart to see a seasoned craftsman at work. Reading how people do and do not clean on these forums/videos etc etc just makes me not even want to attempt it your self. You, on the other hand tell us what to do/not to do while doing it. Clip is sped up i couldn't ask for a better demonstration thank you sir.
Thanks for the great feedback, glad you enjoyed my video. Good to hear you considered me a "seasoned craftsman", but I must confess, this was only my second time doing a SCT, although I have been around optics for some time. I learned the theory of what to do from our optical people at the observatory, which gave me confidence what to do. My "reward" was a comment from an ex-Meade employee which confirmed that I got it right, dispite other "experts" being quite critical as you can see from the comments. Good luck with your cleaning attempt, its not that difficult.
Great video. I work for a company that does vacuum brazing using similar equipment, except the chambers are much smaller. We place a clamshell heater on the outside, and the chamber is heated to about 1000*C while under vacuum (1e-5 mbar) with parts inside.
Exactly what I thought until I pointed my instrument toward a marine horizon.Almost every day I viewed obstruction it came with a higher than eye level horizon.Hard to believe but if you care about truth.......
And there I was thinking of designing a arduino unit. Your method is simple, basic and very functional. Thank you for sharing this. I am going to do this.
Unless you want to design a gadget that needs power, just a simple weight and float will do. Place it such that you can see it from the house, or where ever, it is visible from a fair distance. Happy building!
If that was true, one would expect it to shrink in size, like any other object moving away from you, due to perspective. You can easily test this for yourself - using a solar filter, take a picture of the sun at noon and again at sunset/sunrise, using identical settings. Then compare the two pics side by side. I'll be looking out for your video.
@@SterremanWillie False. We see in an atmohemispheric dome of vision, the sun we see never changes it's distance from us, therefore it would not be expected to change size drastically. It definitely has been shown to be slightly smaller though
All of the videos elsewhere online DEMOLISH this weak argument and slideshow. Flat Earth has all of the data and common sense and you’re not gonna find much of it on FluffToob.
At this point if you are a flat earther we know many things about you. Low education, all around science denier, young earth, doesn't believe in evolution or germ theory, probably antivaxxer.
hi Willie, I finally got time to seat down and compare all the data. I used walter.bislins calculator, and all the information you provided, at 3:04 of your video you can see the Baosteel Elaboration size: 327x55x10.6 After some research I found that 10.6 meters is the freeboard measurement (distance from the water line to the deck ship) when entered all information the calculator was exact on showing a bit of freeboard at 35 km and nothing at 43 km, the calculator can also show the flatearth model and the freeboard can be seen at 35km and 43km. thanks you for sharing your video with the information needed for a real observation, Earth is Round......
At 33km ship should sink 85meter below vision - your hight of 23meter is still 62meter drop, thats a very tall ship must be higher than 62meters that ship ❤❤❤❤❤
I'm sorry my camera and the ship's IAS were telling so many lies.... or are these lies perhaps reality. Go wath my video again and pay better attention where I gave my elevation above mean sea level. Then see how using a proper earth curvature calculator will get you closer to reality.
@@paulwesselson1069 the observer height was 42 metres, but I don't know why any of this is important since the camera saw what ot saw. So if you cannot get the flat-earth curvature calculator to agree, then you are clearly using the wrong calculator, as so many people keep telling you. Otherwise, thanks for calling me a lier!
At 30km ship should be under horizon by 70 meter on globe earthcurvature.cm calculate and find truth water doesnt bend it flows to lower ground ❤❤❤❤❤❤❤
Sjoe, nog nie gekyk hoe om dit op 'n Corsa te doen nie. Ek het dit jare gelede op 'n Renault gedoen deur die afstandmeter uitmekaar te haal, dan kon jy stel na enige km soos benodig, maar nie seker of dit moontlik is met 'n Corsa nie.
I've gotten really good at doing this too with my 1981 Celestron 8 'Frankenscope' (made of the best parts of two that were heading to the junk pile otherwise), and have gotten to the stage when I can clean the corrector to perfection. Tools : PEC Pads, Ultra-microfibres, a lens 'flick' microfibre tool - all of the first three from a specialist camera shop; Tamiya masking tape 10mm, Gundam fine markers (for cork positions on masking tapes), cotton balls, X-acto #11 Stainless Steel blades and handle, rubber gloves (not nitriles), 3 x 250ml lab squeeze bottles for cleaning solution, EtOh, dH2O. Cleaning agents : dH2O, EtOh 95%, Pure SLS (lab grade), and a can of CRL professional hi-sheen aerosol cleaner; Cleaning solution of 20% EtOh:80% dH2O - used to dab on mirrors and correctors with a soaked PEC Pad with zero pressure. Technique : the same as yours for mirror surfaces; I protect the secondary with a spare cotton glove, but will use the pristine microfibre flick-cloth prior to covering with glove. Dabbing with a cleaning solution pec pad, followed by a tube-down rinse with dH2O, and then dabbed with a pristine ultra-microfibre to prevent micro-spots. Gloves in use at all stages. For the corrector - all the same steps for the cleaning, though with absolutely no pressure at any stage of procedings - scratches of even the slightest sort are unforgiveable to me. The soap stage is two-step - SLS first, dry, then CRL spray, blotted, dried - all drying steps with the ultra-microfibres. Done in bright sunlight, to ensure that there are zero streaks or imperfections in the drying stage - about 0.5 Newtons pf pressure is permissible in drying stage, but from the bottom of the corrector being held in-hand by the corrector assembly - the cloth can 'fall away' from the surface, rather than being 'pressed in' and that is super-critical. PEC Pads replace cotton balls for the cleaning stages, when For drying, because it is light enough, I will do the drying by dragging (with no weight) a pristine micro-fibre over the real surface, using the sun to ensure that there are no scratches, and no dust. Identical technique, and another pristin ultra-micro-fibre (I have three per annual cleaning session) for the front surface. Result is something not even Celestron say is possible - a better-than-factory clean. In the process, you remove (for old ones like mine) the wax-coat Celestron put on the surfaces, which gave the optics a 'blue tinge' which everyone thought was a coating. That's about my only addition to the process.
Wow! Very interesting! That's really cool! Thanks for sharing. Good to know I was on the right path at least, but that there is lots of room to improvement! Thanks for watching. Keep up the good work.
I've driven that a bit when I was last in Sutherland at the end of high-school, with my own hands at the big wheels...happy memories of the stars being so bright, that they cast shadows on a moonless night.
Not sure how gold coating is done unfortunately. Other metals are possible, I've seen before. Instead of coils, they sometimes use a hollow bucket-like structure in which the metal is heated to boil off into the mirror.
Good day I got a Corsa lite 1.4 got gear linkage problems maybe you could help can't find anything on internet all is from UK or so 😢 You're videos are so much help thanks
Thanks for the nice remarks. In fact, I also had trouble with the gear shift in this Corsa which I tried fixing, but got nowhere unfortunately. Had to take it to the garage, who said it was only a nut that came loose, but I could not figure out where that could have been!
Watched the movie; 'Something the Lord made' and then searched for our SA version who is Chris Barnard and Hamilton Naki. I am glad Hamilton was recognized for his work at the time.
Hi Willie, I'm Messala Coimbra and I work at the Pico dos Dias Observatory, located in Brazil. My work is similar to yours and I'm learning a lot from your videos. I'm grateful for that.
Indeed, but you need to apply an overcoat over silver because it will tarnish very quickly, unlike aluminium which protects itself with a very thin layer of aluminium oxide and will stay shiny for years.
Big challenge for silver is to apply a coat of even thickness. If uneven by just a few microns, it changes the "shape" of optic, effectively changing / spoiling it.
Thanks, Willie. The Ford handbook says remove the electrical connection BEFORE removing the two plastic 'screws' but much easier to do what you did which was to remove the two plastic 'screws' and whole light casement before removing the electrical connection. Thanks for the video. Bulb changed nice 'n' easy.
Glad to hear my video helped. Just as well I did not have access to the Ford manual! I subsequently found that the RHS light is slightly different and its electrical plug is a lot trickier to unplug - there you definitely need to see to unplug.
I believe it's due to light bending because if you see some videos where the boat was at its half view and you zoomed in with the camera the boat would appear it whole again
@@EMFLambin those videos they did not use a planetary camera like I did which can resolve Saturn's rings. I can assure you, not even a Nikon P1000 could bring back those ships.
@@SterremanWillie You always see the horizon line at your eye level. In fact, if you change your eye level (by standing up, or sitting down) the horizon line changes too, and follows your eye level.
@@jamesroberts6018 That the biggest bullshit story I ever heard! And I still don't see how this change the fact that I photographed ships disappearing over the bulge of the globe earth taken from 40 m above sea level. And how you can quickly "make" a ship disappear by changing your vantage point from that height down to sea level.
@@SterremanWillie I’m not trying to refute what you posted… I’m simply saying that according to perspective alone… things above eye level appear to travel downward… just like when you see an airplane that is above your eye level traveling straight ahead… appears to travel down towards the horizon
Indeed. See link to an excellent video in the comments below, explaining it well. We since worked out the exact visibility "season" which happens to be happening at the moment. They get bright enough to be naked eye - I actually watched them last night.
Thanks so much for the start-to-finish tutorial! Will give it a go if I ever get the chance 🤷♀ The observatory where I work used to be connected to the university. Not anymore since 2013ish. There is no aluminising capability around where I live, as far as I know.
That is a pity! You are welcome to contact me for help, if you ever want to get something going again. We have four aluminising tanks at our observatory, and I got involved at all of them.
Fascinating video! Why it melts entire Al hook at once, not just burning through it in half? Is the current set in a way that the heat propagates through the entire hook?
It does happen sometimes that the hook burns through and the two pieces fall to the bottom of the tank, but, probably thanks to surface tension, the ends get pulled up to the heater to form a bubble. We do turn up the current slowly to try prevent the hooks from burning through.
