Moving out from Titan, Hyperion is a lot fainter at mag 14.2, but is sufficiently far from Saturn when at elongation that you can move Saturn out of the field of view to reduce the bright glare; it can then be seen in a good 25cm telescope. Next is the mysterious Iapetus, the two-faced moon. One side is considerably brighter than the other, and as its rotation period is tidally locked to Saturn that means that it is always considerably brighter when at W elongation (10.2) than at Eastern (11.9), as on 21 June.
2. MARS still bright: Anyone looking at the S night sky for the last week or so can't have missed the glorious red beacon of Mars in Scorpius, which was at opposition on 22 May, and closest to Earth on 30 May, when its distance from us was 0.5032794 AU (~75m miles), and the apparent diameter was 18.4". It was mag -2.0, almost equal to Jupiter. It currently appears about 3 magnitudes brighter than its 'rival', Antares, which is a mere magnitude + 1.0.
By the end of June 30 it will fade to -1.4, with a diameter of 16.4". The N Pole is tilted towards Earth by about 10° but the N Polar cap will be small because it's Martian N summer.
