3 The cluster

NGC7419 (C2252+605) is a small, young open cluster in Cepheus, known mainly for its five M-type supergiants (Blanco et al. 1955; Fawley & Cohen 1974; Beauchamp et al. 1994, henceforth B94). The coolest of them is MY Cephei = IRAS 22525+6033, an Lb or SRc-type variable of spectral type M7.5I, known also to be an H₂O maser (Dickinson et al. 1978) and an OH/IR source (Alcolea et al. 1990). The age of NGC7419 was estimated by Bhatt et al. (1993) as smaller than 40 Myr, while B94 derived that it is equal to 14 $\pm$ 2 Myr. The average reddening, in terms of E(B-V), amounts to about 2.0 mag, but a differential effect of the order of 0.4 mag is also observed (B94). The average total absorption in the V band, as estimated by the same authors, amounts to about 6.7 mag.
