This is a good combination...the wide fields of the Sky 90 and its 500mm focal length coupled with the Mewlon 210 (Dall Kirkham Cassegrain design), a 2410mm focal length instrument. Each scope does something the other is incapable of. The 90 goes wide and the 210 goes deep. It's a pleasure using them together.
