A sample of five rich galaxy clusters has been mapped by ISO at [FORMULA], [FORMULA], [FORMULA], and [FORMULA] using the PHT-C camera. In previous papers Abell 2670 and Sérsic 159-03 were discussed. Here we present the results for Abell 2029, Abell 2052, and Abell 2142. The conclusion of the survey is that the relatively small fields ([FORMULA]60 square arc minutes) are structured with filaments or superpositions of point sources. In some cases point sources ([FORMULA] Jy) can be identified with cluster galaxies. An attempt to demonstrate infrared emission from dust in the cooling flows (due to star formation) was inconclusive.

Key words: galaxies: clusters: individual: Abell 2029, Abell 2052, Abell 2142 – infrared: galaxies
