The article First Light: a new era for the Royal Observatory says (in part):

25 June 2018

The first modern, research-grade telescopes have just been installed at the Royal Observatory Greenwich, making the institution a working observatory once again after 60 years. Marek Kukula, Brendan Owens and Tom Kerss explain what this will mean for them, researchers, and the public.

"Modern equipment has allowed us to bypass a lot of the disadvantages that drove astronomy away from Greenwich in the middle of the twentieth century."

How exactly will "modern equipment" do this? A blocking filter for the bright yellow sodium line of some streetlights might have some effect, but with high pressure mercury lights and now broadband LED illumination, what other tricks do Greenwich astronomers have up their sleeves?

AMAT’s dual role is aptly matched to its name-sake. Annie Maunder explored the night sky and its phenomena as an astronomer, astrophotographer and science communicator in Greenwich during the 1890s and early 20th Century. She was hired as a human computer at the Royal Observatory in 1891, and though, as a government employee, she was required to give up her position when she married fellow Greenwich astronomer Edward Walter Maunder, she continued to participate in science, publishing books to inform and inspire others and returning to work at the Observatory during the First World War. She was also one of the first women to be elected as a Fellow of the Royal Astronomical Society in 1916. By the end of her life she had gained an international reputation, particularly for her work examining the Sun during eclipses for which she designed her own specialised cameras.

It's a little hard to guess what research can be done there -- Today, Greenwich is close to the worst place on Earth to have an observatory: At sea level, in the light dome of one of the largest cities in the world, in a country famous for its clouds and fogs.

The Wikipedia article on the observatory mentions the new telescope and says:

In 2018 the Annie Maunder Astrographic Telescope (AMAT) was installed at the ROG in Greenwich. AMAT is a cluster of four separate instruments, to be used for astronomical research; it had achieved first light by June 2018:

  • A 14-inch reflector can take high resolution images of the sun, moon and planets.
  • An instrument dedicated to observing the sun.
  • An instrument with interchangeable filters to view distant nebulae at different optical wavelengths.
  • A general-purpose telescope.

At a guess, they hope to do some sort of star position measurements which is one sort of astronomy that is less affected by haze and light pollution (though it needs steady air -- I have no idea what the air steadiness is like there). But even that is still better done with larger instruments in better locations, and by satellites such as Gaia.

It really sounds like a public outreach facility or an undergraduate training site more than a research facility. It's also worth noting that the pictures show equipment that is at the serious amateur level -- I certainly know amateurs who have better equipment.
