49. IRAS 17500+7230. B–V = 1.631 (Tycho2), J–H = 0.849 (2MASS). The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

50. IRAS F18141+3009. B–V = 2.226 (Tycho2), J–H = 0.874(2MASS). Type SR is not excluded. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

51. B–V = 0.855 (Tycho2), J–H = 0.590 (2MASS). Faint close companion GSC 2740-01090, J–H = 0.245 (2MASS), the NSVS amplitude is slightly underestimated. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

52. IRAS 23536+7043. J–H = 1.003 (2MASS). Type SR is not excluded. Faint close companion GSC 4483-01506 the NSVS amplitude is slightly underestimated. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

53. IRAS 23551+6844. J–H = 1.674 (2MASS). The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

Remarks:
I present the discovery of 53 new semiregular (SR, SRB, SRD) and irregular (LB) pulsating variable stars. A search for variables was carried out in the publicly available data of the Northern Sky Variability Survey (NSVS; Wozniak et al. 2004) and The All Sky Automated Survey (ASAS-3; Pojmanski 2002). These observations were analyzed using the period-search software developed by Dr. V.P. Goranskij for Windows environment. The coordinates were drawn either from the Tycho-2 or 2MASS catalogs.

In several cases, the ROTSE data with photometric correction flags (usually rejected) were kept for the analysis. The use of these data considerably increases the number of available observations without deteriorating quality and allows us to determine the period more accurately.
