If you are staying free hand holding then really the binos you have are suitable. However they are both close in terms of aperture and magnification - but the 7x50 does give you a wider FOV at around 7 degrees Tfov. which is good for wide angle scanning. The Orion is narrower at 5.8 degress.
One option could be to sell the Orion and get something like a AOE 11x70 -which is still hand holdable but will enable you to noticably gather more light and see deeper. AOE and others do also sell a high quality 10.5x70 'Ultra' WP version which has excellent optical and build qualities but it is heavy.
A 70 mm size bino on a dark sky site will give you impressive viewing.
A 7x50 and a 11x70 would be a good combo.
Dew heater strips are available - try AOE or Bintel.
Mine is but one opinion - ask around and see what others say.
