tool to precover NEAs in the SDSS DR8, then later the similar SVO-ast project to measure NEAs and Mars-crossers in a collection of surveys (SDSS, UKIDSS, VISTA and VSS) [@Solano2018].\
Besides astrometry, image archives are valuable also for deriving photometry and physical properties of astronomical objects. Popescu et al. [@Popescu2016; @Popescu2018] retrieved the asteroids imaged by VISTA Hemisphere Survey, obtaining near-infrared colors for 53,447 solar system objects including 57 NEAs, 431 Mars Crossers, 612 Hungaria asteroids, 51382 main-belt asteroids, 218 Cybele asteroids, 267 Hilda asteroids, 434 Trojans and 29 Kuiper Belt objects.\
In 2010 we introduced the [*Mega-Precovery*]{} project [@Popescu2010], aiming to allow public searches of one or a few asteroids or NEAs in a large collection of image archives which aimed initially to include at least one million images. This project’s capabilities and databases have been strengthened during the last years [@Char2013; @Popescu2014; @Vaduvescu2013] and in this paper we present the latest version of [*Mega-Precovery*]{}. To our best knowledge, there is only another similar web-tool allowing searches of asteroids in a large collection of archive images, namely the “Solar System Object Image Search” (SSOIS)[^6] hosted at CADC in Canada. This project was published first in 2012 by S. D.
