TX Psc is a very bright, nearby star which is well studied and of interest to professional astronomers. One observer from the BAA-VSS logged a few observations back in 1887 after which the star seemed to have been forgotten about until 1947 when regular visual observations picked up again. There are currently 13,515 observations in the AID, 91.6% of which are visual.
