[3][4][5] The visibility of several background galaxies in the NW corner of the cluster indicate that the obscuring medium may be lowest here.

[4] Due to the uncertain amount of interstellar reddening, precise determination of age for this cluster has been especially difficult.

Although thought to be an old cluster, NGC 7142 contains a surprisingly high number of blue stars.

However, their investigation only spanned two days, which did not afford enough data points to determine the type of variable.

Roughly two more nights of data were appended to the beginning of the Crinklaw & Talbert study but have still not given enough information to classify the variable star.
