Description

This is a quick test of the new TS 71SDQ scope. The TS71 SDQ is a Quad APO f6,3. It is also known as the Sharpstar 71SDQ in some markets. Scope has a 450mm focal length, with a 44mm fully corrected and illuminated image circle.

This test image was taken with a Nikon D5300, so the maximum image circle size was not fully tested by this camera. Image consists of 35 x 60sec subs shot at ISO1600. Bias and Darks were used. Processed in DSS and Photoshop CC.

The image degrades when translated here to jpg from the original TIFF post-processing file.

Some evidence of what might be tilt appears in the lower left corner, and needs further investigation.
