A precise collimation is necessary to see the planets sharp and up close. At f/5, the 6" Newtonian won't be too difficult to collimate, compared to a 6" at f/4, but being a collapsible that will work against you somewhat when compared to a solid-tube affair, like my own 6" f/5...
The telescope, with its 750mm focal-length, is nigh an all-rounder, versatile, for observing most everything in the sky, from 23x, to 200x and beyond.
If you choose a laser to collimate, the unit itself will most likely need collimating upon arrival, and before using it to collimate the telescope.
For my reflectors at 6" and smaller, I use passive tools, like a Cheshire/sight-tube(with cross-hairs) and a collimation-cap...
