  1. As the OP I am going to throw my hat into the ring…

    1, Newtonian

    2, Dobsonian (not sure on the rules but the biggest injection to amateur astronomy in history and he gave it up for free)

    3, Stellarium, the only night sky I can see most of the time and I can see far farther with more detail than my scopes.

    Hubble Space Telescope: It is the source of all those pretty pictures whole generations have grown up seeing as THE bar for quality. Plus it allowed us to see back to near primordial times in a cosmological sense and continues its primary mission of observing and measuring extra galactic supernovae to this day, over 30 years later! Plus it was put into orbit in a space shuttle, one of the coolest things to ever fly.

    VLT: One of the first observatories to use a laser guide star system for adaptive optics, and THE best interferometer used for astronomical purposes. Besides being a technical marvel and living breathing science and technological development of the most impressive order, it also pinpointed the exact location of the black hole at the center of our galaxy and constructed an image of betelgeuse with surface detail!

    Arecibo: aside from simply being massive and cool (the dome was a 5 story tall building by itself!), the telescope's ability to perform active radar imaging of asteroids was pretty unique and cool. It also captured the minds of many.

    And the third one was in a bond movie!

    To be honest, the Holmdel Horn Antenna wasn't really an Astro scope. 

    Mine - of ones not mentioned

    • Hale 200" Telescope at Mount Palomar
    • WMAP
    • Bessel's Fraunhofer Heliometer Telescope

     

     

     

    I have no objection to odd ones that don’t fit the mould. Is the horn antenna the one that is threatened by a housing development in the US?

    Your third choice is something I have to look into.

    Thankyou for not coming back with red dot finder three times.

    Marvin I think we are being rebellious because we are fed up with this winter weather.  Let it run, I bet some better educated suggestions will start coming in.  Although I do like your Red Dot finder suggestion; I would have offered the Telrad but I'll keep that in reserve for now.

    Perhaps I am just a bit edgy as I just got out and looked at the moon for ten minutes. Almost the first Astro in a month!

    Jansky was the scientist, his 'scope' had no name, it looked like a fairground ride with wires, But who knew before that about radio waves from space? Need 3 eh, in that case Palomar 200inch and Gaia.

     

    So far Mr H in Yorkshire you lead the field. With a fairground ride and what seems to be a quick add on😂

    The telescope used by Nelson at the battle of Copenhagen when he he raised it to his blind eye and said "I see no ships" .  He had been ordered by the admiralty to leave the area because of the approaching enemy fleet. He didn't want to go (he was in fighting spirit) , so having seen "no ships" he loitered and subsequently won the day :) 

    Ok , hat and coat I know the routine.

    Not Astro scope and only one.

  7. Just to prevent repeats the big question is “The most important three telescopes in history with the exception of Galileo first scope and JWST.

    So many scopes from Radio to visual, Solar, Space based, terrestrial, what was observed, or even more importantly what came from the observations. Odd ones like gravitational wave detectors if people think they should be included?

    The elephant in the room is of course Hubble, but that scope was named after a man that used a famous scope to discover galaxies and is credited main stream with proving expansion.

    1.2.3. Simple really. Marvin

  8. I consider it the greatest achievement in my life time, as I shot out of mum ten minutes before 17 shot into the sky!

    I also love geology so Schmitt is a bit of a hero of mine. I remember reading somewhere that some people had a nickname for him “Bull Schmitt”.

    However, none of those people walked on the moon.

  9. 123star, you have done good thing and with the great advice you have received above you have not made any impulse purchases.

    Great advice, colimation cap. Dew shield essential. Eye piece upgrades one at a time, slowly slowly.

    At my entry into Astro five years ago I was bought a box of Super Plossl’s. In short they are good 1.25” all metal EPs. 
    They are still my eps today. 

    I went off a rapid tangent towards Astro photography at a limited level. 
    However, I have now mounted my first scope 130 newt Orion on a portable alt az mount, and it is a joy.

    Never underestimate what a potent bit of kit a 130 is under darker skies. It has saved my observing sanity as a grab and go so think twice before selling it in the future for an upgrade. You might find you come back to each other a lot later on.

    If you can afford it, think about passing it on to a youngster if you know you are done with it. Invest in the future.

  10. Unexpectedly clear tonight with incredible stillness but countered by light glow from fog starting to build. 
    So I had it great but the conditions were going against me. I don’t mind as anything without cloud and snow is a joy.

    This is an odd one. I opened an Astro book yesterday and there was a bookmark in the section Monoceros. I probably left it there as a reminder to AP the Rosette. I looked at the constellation and thought why not give it a go visual?

    Right next to Orion, easy peasy. Not so! When the books say a faint constellation they are not joking. Under B3 skies the whole thing looks like a really dim bit of the milky way.

    Monoceros is the proud owner of M50 but I decided to go big game hunting. Plaskett’s Star.

    I stumbled upon this star in Burnhams which has the usual amazing description with all the trimmings. So I decided to give it a go with my five inch newt on an AZ5 with decent Plossl EPs. 
    No high end kit. No power. No goto or computers. 
    Beginners heads up. A decent star atlas. Something else to cross reference it to and plenty of dark adaptation.

    Monoceros is a visual nightmare. There are so few stand out stars that the whole thing melts into the background stars. Navigation is so hard. At first I was at despair but then I thought, use your time and work methodically. 
    Go back to a known starting point and hop again. It took me at least ten minutes to work out where 13 Mon was for sure.

    From 13 mon there is a little triangle of stars that point in the correct direction. As usual every thing is the same magnitude even though the charts say otherwise. Another 30 minutes of back and forth an there are the three stars, the right one is Plasketts.

    It just looks like a star, but it is different to the others in the fov. It is pin point sharp. Very white and intense. All the other stars look like background points of light.

    To end it all I star hopped to M50, rude not to. I will leave you all to look into Plasketts Star. But I will end this by saying to all astronomers, the joy of a grab and a go can re energise your love of astronomy.

  11. Great work everyone. I don’t care if it is perfect or if it processed correctly. I saw this in the EP two nights ago and these images far surpass that. Although the view in the EP had more green.

    Round of applause from me. I am loving this comet as I have actually seen it for once but so many people have different images of it. I hope you don’t mind me wrecking it with a smart phone pic if the clouds disappear.

  12. Just come in to warm up, five below out there with snow on the ground. 
    Despite the forecast saying heavy cloud my inner comet clock woke at five am and kept nagging.

    Completely clear outside so I grabbed the 5 inch newt on the AZ5 with a 25mm plossl and headed out. My skies are quite dark so I was expecting this to be simple and obvious which it was not.

    Using the end stars of Ursa Minor as a pointer into Bootes, then a guesstimate of the area using a Skyhound chart it was in the EP.

    Definite green colour as others have reported. Very soft and diffuse, with a very short fan shape. Off centre core which is tight and bright white with slightly averted vision.

    Very happy to have seen it as the weather has not been kind. Back off to a warm cosy bed and a Sunday layin🙏
