Description

This is a first light test image for a newly acquired Takahashi TOA-130NS refractor. I used a Televue REF3007 x0.8 field flattener/reducer with a Canon 450D as a temporary measure to conduct this first test. The FF/FR isn't optimal for this scope so I'm waiting for a matched Takahashi x0.75 FF/FR
