After imaging M 51 and with a desire to see if the improved guiding was maintained when imaging my more usual area of sky I found this patch of bright nebulosity in Vulpecula. It is Sharpless 2-90 and I was able to obtain a dozen subs before the sky was noticeably beginning to lighten at 2.30am revealing how short the available imaging period is at this time of year. It was pleasing to see the guiding maintained the improved performance with the scope at its more usual balance setting. Details: 10" f4.3 Newt. 12x 10minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
