M35 & NGC2158 
Open clusters in Gemini
Uploaded 2/18/16

This pair of clusters in Gemini represents an extreme 3D effect - The smaller star cluster to the lower right of M35 is 10 times further away, making this an optical double rather than a binary cluster. Both are a stunning sight in larger apertures. This pair of clusters was imaged to check the sharpness of the stars across the field when the six inch is properly laser collimated. The results here look good, and this astrograph is ready for shooting deep sky objects and comets.
