The question is: If I put a different power supply on that is 12v DC using 5.0 amps will the increase in amperage effect the DC current flow?
Substituting a bigger power supply more amperes capability will accomplish nothing regards voltage drop on a longer length of wire.
You need heavier wire for the longer distance of 12 volt run. Now if you can run 120 volts closer to where the telescope is so the 12 volt line is much shorter then you will not have the voltage drop problem.
For the same piece of wire the number of volts dropped (lost) is the same for a given number of amperes regardless of the voltage. Losing 3 volts out of 120 almost never causes a problem while losing 3 volts out of 12 almost always causes a problem.
For electronic equipment do not try to use a higher voltage power supply given the distance to overcome voltage drop problems. The voltage will vary as the equipment amperes draw varies and can burn out the equipment.
