All-image limiting magnitude estimate:  12.9 (SNR )   9.9 (80% of stars)  with default.sex.telephoto_lens_onlybrightstars_v1
The first estimate is the magnitude of a star detected with a signal-to-noise ratio of  following Karpov (2025, Acta Polytechnica, 65, 50). 
This value should be representative of the faintest stars clearly visible in the image. 
The brighter of the limiting magnitude estimates for the two second-epoch images is reported here.
The second estimate is the 80th percentile of the magnitude distribution of stars detected on all four images.
This value is representative of the faintest object that may enter the candidate transients list.
The hard cut-off for the candidate transients is 15.5 mag.

UCAC5 local query limit 5000: matching up to 5000 detected stars, deepening the UCAC5 window to mag 15.50
Reading UCAC5 zone files...
Searching UCAC5 zones 453 to 508 (Dec 0.7 to 11.3)

Matched 672 stars with the local copy of UCAC5.
The local UCAC5 search seems to be a success
SIP_REFIT: re-match found 672 pairs (716 from the initial matching)
SIP_REFIT: SIP order 2 trial: matched=672 robust_rms=5.560 arcsec worst_quadrant_rms=9.421 arcsec
SIP_REFIT: SIP order 3 trial: matched=672 robust_rms=0.567 arcsec worst_quadrant_rms=0.657 arcsec

SIP_REFIT: the refit on the re-matched pairs is worse than the solution it would replace (worst-quadrant 0.657 vs 0.655 arcsec) - keeping the current solution
SIP_REFIT: the second refit on the re-matched pairs was not applied - keeping the first refit solution

All-image limiting magnitude estimate:  13.1 (SNR )  12.5 (80% of stars)  with default.sex.telephoto_lens_vSTL
The first estimate is the magnitude of a star detected with a signal-to-noise ratio of  following Karpov (2025, Acta Polytechnica, 65, 50). 
This value should be representative of the faintest stars clearly visible in the image. 
The brighter of the limiting magnitude estimates for the two second-epoch images is reported here.
The second estimate is the 80th percentile of the magnitude distribution of stars detected on all four images.
This value is representative of the faintest object that may enter the candidate transients list.
The hard cut-off for the candidate transients is 15.5 mag.
