The GOTO telescopes

GOTO telescope concept
A rendering of the GOTO telescope: a single mount can carry up to eight wide-field telescopes. Starting initially with four telescopes, the project is easily scalable.

The telescopes are deployed in phases, and the project is set up such that it can scale easily.

Initial Phase - current

The first phase is operating at the Observatorio del Roque de los Muchachos, on the island of La Palma.

Four 40 cm f/2.5 unit telescopes on a single mount fitted with 50M pixel detectors were deployed in June 2017 . This delivers approximately a five square degree field of view per telescope, with a pixel scale of 1.25 arcsec. A wide optical passband L filter is used allowing to reach a depth of 20 - 21 magnitudes with sets of 3x120s exposures (depth is largely dependent on sky brightness/the Moon phase). During currently ongoing commissioning stage sky monitoring of selected regions of sky is also performed through set of R, G, B Baader filters.

GOTO telescope - 4 OTAs

Second phase

The telescope will be scaled up in summer 2018 filling up the mount in the first dome with 8 telescopes to cover a total 40 square degree field of view.

GOTO telescope - 8 OTAs

Third phase

A third phase foresees a further set of telescopes in a second dome, which has already been erected on the same platform.

GOTO telescope - 16 OTAs

Fourth phase and beyond

When additional funds are secured construction of the Southern node is planned in Australia.
