Following on from unguided exposures on the CGX mount, this was 4x 300s iso 200 guided exposures with NexGuide auto guider, Moon was quite bright, sky background light even at this unearthly hour! Star images are small and round, no sharpening has been applied to this image, just exposure contrast and saturation. The CGX and NexGuide combination with 60mm f4 guidescope (with 2x barlow giving 480mm focal guide length) has worked very well and has produced a decent result even with the bright sky. I will try longer exposures and up ISO to 320 to boost image without to much gain in the noise
