Description

Although purchased in February first opportunity to use ASIAir for deep sky imaging. Test went reasonably well, autofocusing and guiding very good however star shapes especially on periphery a little distorted which I think may have been due to pinching the optics of the field flattener. The flattener needs 118mm of backfocus at the 500mm FL of the Equinox 80  which I could only achieve by clamping the body of the flattener in the eyepiece holder rather than using a nosepiece and may have been a bit enthusiastic making sure it wouldnt fall out.
