Fading in and out
Good afternoon everyone.
Equipment: 10" Collapsible Dob
Conditions: Clear sky with dew settling later
Eyepiece: 10mm
Problem: Saturn fading in and out
Query: For the very first time, I had used a filter to look at Saturn. I was like a kid in a lolly shop as even though I had seen Saturn a number of times before, this was the first time EVER I have seen the division in the rings.
My question is that as Saturn was going through my eyepiece, it was clear then blurry, then clear then blurry. All in a matter of seconds.
If it is a collimation issue, wouldn't it be blurry all the time? Why would this happen?
