Help needed: Sky Watcher 10" Dob can only focus on very close objects
Hi, have brought my first telescope which is a Sky Watcher 10" collapsible dob. Currently having issues trying to focus with it. At night I have tried it on the moon which only appeared as a white featureless disk. Have been unable to even see out of focus stars.
Due to these issues I have tried the telescope during the day. Tried to focus on trees varying from a 100m to a few kms away but always have a very blurry view. Yesterday had it out looking at the moon. Once again very blurry and unable to make out even the shape of the moon. Really it was like looking at blurry blue with a hint of blurry white. When I was nearly finished trying to get it working I noticed I was able to focus on some fence wire a few meters away. So figure something must be up as I thought you should not be able to focus on close object.
Have looked through forums and checked I have not made the common mistakes people make when they cant focus. The telescope seems collimated to my uneducated eye. I have it fully extended. Am not using the the 1.25" eye piece adapter with the 2" adapter. Also used some high and low profile adapters to adjust focal length from a mate who looked at the telescope. He couldn't see what was going wrong either.
Any thoughts on what the issue could be would be appreciated
