Thanks Paul, I am asking because I am struggling with the seeing in Coona and wanted to compare. The image you produced looks pretty sharp, with nice tiny stars all over the field and I was imaging you had better seeing than mine, which is apparently similar to yours (2" to 3.1") or a bit on the higher side, mostly around 3" on subs.. I am trying to understand what I could tune on my setup to improve the FWHM but if the seeing is mediocre there is not too much I can do.. That's all
