The Virgo Cluster of galaxies reigns supreme for galaxy fans on spring nights. Its teeming galaxy fields centred both facet of the boundary between Virgo and Coma Berenices are filled with any variety of excellent particular person galaxy gems, however when you’re wanting extra bang on your buck, then observe down Markarian’s chain, a string of galaxies that features Messier 84 and 86 and the interacting pair NGC 4435 and 4438, popularly referred to as ‘The Eyes’.

Markarian’s Chain consists of a line of a minimum of eight galaxies that curves north and east from Messier 84 and 86, simply inside Virgo’s territory, and extends for about 1.5° to NGC 4477 throughout the boundary in Coma Berenices. The entire ‘chain gang’ ought to be inside vary of a 150mm (six-inch) telescope. In early April, the Chain is effectively up within the east-southeast by dusk and goes on to culminate round 50° excessive at about 12.20am BST.
Dominant on the western finish of the chain are Messier 84 and 86, a pair of ninth-magnitude elliptical galaxies (classed as E1 and E3, respectively) mendacity round 17’ aside some 5° north-west of magnitude +5 rho (r) Virginis. As a problem, if you’re utilizing a telescope within the 300mm (12-inch) class, shift your gaze barely to the south of M84 and M86 and see when you can spot NGC 4387, a magnitude +13 galaxy that spans simply 1.7’ x 1’.
The subsequent two hyperlinks within the chain, NGC 4435 and 4438 (additionally catalogued as Arp 120), the interacting ‘starburst’ pair often known as ‘The Eyes’, are probably the most attention-grabbing. NGC 4435 is the smaller, extra northerly galaxy of the pair, a barred lenticular that, shining at magnitude +10.8, is fainter than NGC 4438, its bigger and much-disrupted neighbour (+10.0), although it reveals a better floor brightness.
Transferring additional north and east however staying in Virgo sees NGC 4461, a 3.7’ x 1.5’ eleventh-magnitude spiral, with NGC 4458, a smaller and spherical elliptical, simply to the north. A 150mm (six-inch) telescope ought to present the previous however you’ll most likely want a 200mm (eight-inch) ‘scope for the latter.
The final hyperlinks within the chain lie throughout the boundary in Coma Berenices. NGC 4473 is a magnitude +10.2 class E5 elliptical spanning 4.5’ x 2.6’ and, lastly, mendacity round 12’ north is magnitude +10.4 NGC 4477, one other spiral which covers 4’ x 3.5’. Each galaxies seem related by way of a 150mm telescope.
