Literally a 10-minute process of data taken on the Hyperstar III last night. As it was clear (?????) I set up the Hyperstar to do a bit of imaging while I worked on the mini-WASP array. Collimation was poor and I didn't spend any time tuning it, so this is just the central crop of a bigger image. 68 one-minute subs dithered.

If the weather gives me a chance I will do this one again with the Hyperstar - this time with even shorter subs, and with much better collimation. The collimation was an awful 9" for this image - I don't usually image unless it is less than 2.9" according to CCDInspector.
