Hi all,
Its been a while since I have posted on these forums, and seems like even longer since I have been out under the night sky with my scopes. Turns out having a second child really puts a stop to all your night time activities
So to my question, how do you know when your primary mirror needs to be cleaned in a 8" newt? As I mentioned it has been sitting for a few months unused but stored with all dust covers in place. I took the main cover off to look at the mirror and it has a few specs of dust on it, i can only see the dust under torch light just kind of like a few specs here and there.
So will this effect my viewing at all? I really don't want to pull the mirror out to clean it, i have done ot on my smaller scope once before but that was only becouse I had to remove it anyway to place a donut in its centre for collimation.
Thanks everyone lets hear all your opinions.
Dan
