One of the LARGEST Amateur Visual Telescopes on Earth!!!! 70-inch Aperture!

One of the largest amateur telescopes lives just outside Salt Lake City. 70-inches in diameter! Huge! Mike Clements takes us on a tour of his hand built 70" Newtonian reflector style telescope. Mike made this out of inspiration from an old satellite blank that never made it to actual space use. This is one of the largest amateur telescopes available to the public on the Earth and it lives probably close enough to some of you! This telescope has been talked about and featured in numerous articles and forums across the globe.
******ASTROPHOTOGRAPHY EXPECTATIONS******: It’s not just that simple with this telescope and I know a lot of people have asked. Astrophotography using an Altazimuth design like this one introduces field rotation. This a common problem and it can be overcome with short exposures with focal lengths under 1500mm generally. This is combated using an EQ mount. But with a focal length of over 11,000mm and unstable seeing conditions, you are rarely ever able to take advantage of this aperture and magnification. For example, using a 40mm eyepiece is already 275x magnification. Most telescopes like a C11 can’t use 275x on some nights due to atmospheric turbulence. And this marvel, that’s the LOWEST it can go. Using a camera is going to deliver rotation and very fuzzy photos due to atmospheric turbulence. You will never be able to get short enough exposures, track precisely enough and avoid the atmosphere to get a clear and sharp photo 99% of the time. Even with a smartphone. Mike has configured this as visual instrument only and that is what it’s best at. I understand this may disappoint some folks, but we must respect his hard work and dedication on a part of the hobby he desires the most. His love is visual, not photographic.

The mirror for the 200” Hale Telescope at Paloma’s Observatory was cast as a solid disk but had a 70” hole cut into it. That 70” piece of glass disappeared for decades but was located in a warehouse in Tasmania (of all places). It was purchased, brought back to California in the 1980s iirc, ground, shaped and figured and installed in an amateur scope on a hilltop above Fremont California. One never hears much about it.

@1DesertPirate 9 ай бұрын

Could you possibly be writing about the reflector in Fremont Peak State Park? If so, it is a 30" reflector operated by the FPOA. There is a group in MacArthur, CA, Group 70, which is building a 70" reflector with an extra blank made for the 48-inch Schmidt camera on Palomar Mtn. The 48-inch Schmidt camera uses a 70-inch main mirror and they poured two blanks just in case one didn't work out. As an aside, the 120-inch Shane reflector at Lick Observatory uses the 120-inch test blank poured in preparation for the pouring of the 200-inch Hale telescope mirror. All interesting history.

So the question that immediately comes to my mind is what is the setup time and how much do you need to disassemble the scope to transport it out of the storage building. I have a 24” Starmaster Dob that uses wheelbarrow handles to roll it out of the storage building and along a sidewalk to a circular concrete pad very similar to yours. 70” is absolutely incredible. Thanks so much for sharing Mike. The way you designed the scope to move the eyepiece down to ground level on a Dobsonian is absolute genius.

@@MaximumAstronomy First of all, Thanks for taking us close to Mike's awesome telescope. If I understand correctly, field rotation would prohibit long exposure photography due to rotation of the target in the field despite being tracked. But I guess that it should be possible to take pictures of like 5 second exposure (and with not too much magnification to handle seeing), cuz there won't be much rotation in, say, 5 seconds. And targets like moon shouldn't need much exposure time at all.

@MaximumAstronomy Жыл бұрын

No it was a mirrored finish when he bought it. It was a spy mirror that wasn’t configured just to the governments standards. So he built around it to form the telescope. To move the telescope it’s sat on several bearings which you can move the telescope relatively easily across the night sky, and it will track from there. You do have to keep the Altitude axis counterbalanced to help the tracking motors and engage the “clutch” so to speak for the azimuth to engage tracking or disengaged to move across to another target.

Technically speaking, the monster is a Single-Fold Herschelian -named for the design first used by John Herschel , essentially an (slightly) off-axis Newtonian to maximise light gathering from poor reflectivity in the 18th century. There has also been an article posted in March 2004 Sky & Telescope for making an 6" unobstructed instrument.

@ksm3220 Жыл бұрын

Mike's is not Herschelian but Newtonian, the 28" 2ndary obstruct the 70" aperture

@JamesAAshton Жыл бұрын

A Herschelian is off axis; the axis of the parabolic mirror doesn't align with the axis of the telescope tube (or truss in this case). This monster does have the mirror aligned with the truss so the centre of the image goes straight back to the secondary in the middle. It's only different from the usual Newtonian in that the angle of the flat secondary is not 45°.

The largest optical telescope in the solar system is Hubble at a good 90ft aperture and can split double stars closer than 0.01 arc seconds. For a larger telescope than that, one would have to go to another solar system, perhaps Proxima Centauri B, where, who knows, there might be an optical telescope of a mile or more in diameter, which might be able to see Earth clearly.

With its 11-metre focal length the image of the moon would be 95mm (close to 4 inches) across. That's way beyond the sensor size of even professional movie cameras. Even a full-frame camera (43mm diagonal) would show only a small fraction of the moon in any one shot. You wouldn't see any more detail than in other telescopes either, because the shimmering caused by the atmosphere is what limits resolution beyond quite small instruments.

Реально полным полно видео про 50-70 дюймовые телескопы, какие они огромные и крутые, как их весело собирают куча людей, как перевозят их на колёсиках, как то как это, а даже Луну никто не показал через этот телескоп..😅

Просто банально снимите видео Луны как есть, ничего сложного абсолютно.. прикрепил камеру, навелся на Луну (даже никаких трекеров не нужно, просто руками навёл да и всё) и готово

I love how this is as janky as it gets while still being the biggest diy telescope. I just wish you put your camera to the eyepiece to see what we could actually see.

You will never capture in a camera what you see in a telescope.

Disappointing that we didn't get to see an image.

Unfortunately the telescope is set up for visual and the extremely long focal length makes astrophotography very difficult due to field rotation and the magnification. The atmospheric conditions have another factor and with higher magnification and aperture you can get blurry images of the seeing conditions don’t deliver a clearer image with a telescope this size. Long exposure would be difficult since this being Alt/Az you will have field rotation quickly. Not saying it can’t be done, but certain a huge challenge.

It was a Halloween party since this was filmed right around then. So to be funny that’s what some of the members did for some entertaining humor at the observatory!
