Orbital Behemoth Cannon MK.II

The Orbital Behemoth Cannon MK.II is pefect for taking out planetary bases or space stations from a great distance. The shell it launches can take rocket hits and heavy machine-gun fire and still hit it's target for massive damage. It can be auto-fired with included timer blocks, or manually fired which I feel is more fun imo.
How to use:
You can use the camera to aim with high precision and then:
1. Turn on the merge block
2. Engage welders.
3. Active pistons forward then again to retract.
4. Release the merge block
5. Fire by turning on the Gravity Generators (make sure to turn off the gravity generators after firing).
**WARNING**
DO NOT FIRE WHILE MOVING!
Note: You CAN extend the piston into the gravity field with a built shell in the barrel and use the mass to propel the ship forward at great speed just don't release the merge block!
