The following are a few never posted open star clusters taken with the Celestron 8/AVX and Meade DSI back on 1/14/2016. Lacking notes I have estimated the fields of view based on ratios of measured object radius and image width. The average FOV was 32x26 arcmin corresponding to F/3.3 indicating inline use of the Celestron F/6.3 and Atik 0.5x focal reducers. Images were made before acquiring an auto-guider and thus are unguided. The AVX mount's all star polar alignment combined with relatively short exposures yielded nice round star images.
