Testing the monochrome Mintron 23S85HC-EX-R with a Kson 135mm Newtonian reflector

A composite frame from two images synthesised from 50 integrated frames each with dark-frame subtraction
The two images were stitched together using Jon Grove's iMerge software
There was a bright half-Moon above Orion so a Neodymium moon-glow filter was used in conjunction with the 0.5 focal reducer and UV/IR cut filter.

A single frame showing what the live view was like
With a telescope of significant light-grasp, the live views become very good.
