A deep cycle battery is good - Gel is probably the technology to choose (excellent cycle life, supports deeper discharges before sulphation).
105Ah is overkill though unless you're going bush for a week.
Your EQ6R will draw about 1A tracking and 2A slewing. At 50% depth-of-discharge (when voltage drops to about 12.35v), that gives you around 50 hours continuous operation. At 75% depth-of discharge (when voltage drops to 12.0v) you'll have around 75 hours continuous operation.
The greater the depth of discharge, the shorter the battery life - a common recommendation is to keep it to 50% or less, but 70% is acceptable for irregular use.
You'll need to work out how often and for how long (between re-charges) you intend to use the battery.
