Cocoon Nebula Wide Field

Having spent a night last week imaging some delight from the south. Upon processing the smallest stars appeared as donut shaped. My focus was off my 100th of a mm test images looked ok but it wasn't until they were stacked and processed you could see there was a problem. So last night was really just a test to try and put in place a good focussing technique. I started with π2cyg a 4.4 mag star less than 3° from my target. I use my bahtinov mask to achieve a near perfect focus. I then switch to Imagesplus and fine tune using the FWHM process. Overall I was pretty happy with what was done. Time was now gone 1.00am and work loomed for the next day. So I ran a 30 x 1 minute exposure at Iso1600. Deleted 2 subs and stacked a series of 28 frames to give me this shot. High in the North east under a very poor sky. I will endeavour to have another go later this year when positioned in the west and a good dark sky.
