Observing Arp's
Altas of Peculiar Galaxies

Arp 217

Dr. Halton Arp published his Atlas of Peculiar Galaxies in 1966. It was mainly compiled from images taken with the Palomar 200-inch telescope. Despite that, with modern CCD cameras, they are all within reach of back-yard observers. No only that they are some the most famous objects in the sky. Since then Arp has fallen from favour with his controversial views on quasars and redshifts, now almost universally discredited. However this should not overshadow his other work and we owe him a debt of gratitude for his Atlas of Peculiar Galaxies.

The List of all 338 Objects/Groups - the definitive list derived from the ADC data (PDF format).

Because of the number of objects I have had to split the finder charts below into 4 sections.

Chart 1 of the Atlas RA 0 hours to 6 hours.
Chart 2 of the Atlas RA 6 hours to 12 hours.
Chart 3 of the Atlas RA 12 hours to 18 hours.
Chart 4 of the Atlas RA 18 hours to 24 hours.

Images I have taken of the Arp Galaxies - telescopes from 8-inches to 16-inches.
