The Deep Space Catalog project's purpose is to accurately re-measure positions, sizes, and orientations of non-stellar
deep sky objects from photographic images (primarily Palomar Sky Survey II plates) astrometrically fit using UCAC4 stars.
This is a combined catalog incorporating data from other catalogs (Radial Velocities, Magnitudes, Classes)
Many catalogs contain entries copied from previous catalogs without verifying the accuracy or even existence of the object. Every object in DSCN is verified and measured from images using custom software written by me. This is not a bulk automated search, each object is individually selected for measurement from the images. This takes time which is why donations are needed to keep the work going.
This is an on-going process and updates will be released every month.
