Sydney "Seeing"
Hi All,
I am new to this forum and I have got my GSO 10" DOB out for the first time in a coule of years and Im not sure if I have a collimating problem or is the "SEEING" particularly bad in Sydney the last few nights.
Defocusing produces lots of sparkles
My scope has never been collimated but was excellent the last time I used it and stored well.
Any thoughts would be appreciated and what a fantastic resource this site is.
Thanks
Ron
