Hi guys,
Thanks for the detailed replies, I really appreciate it.
I have unscrewed the pressure tuning all the way before but not prior to each observation. Will try that again. I am not seeing any texture on the disk, no orange peel fee which is what I was expecting.
I have just checked the blue filter tonight, looks good too.
I definitely want to try and replace the O rings, maybe it it the issue.
When turning the tuning knob I cannot see any difference in appearance whatsoever from total unscrewed to completely screwed in.
I seems there is some resistance to the tuner but I am unsure as to whether this is from the pressure or simply the thread.
I am definitely focused, I have spent quite a bit of time on the focus at various magnifications, starting with a 22mm eyepiece. Even when using a 11mm and the 11mm with the Barlow, I am not seeing any surface details or texture.
Peter, so far my experience seems similar to yours, and I would gladly take you on your o ring offer, definitely the first thing to rule out I reckon.
How tight is the margin to see surface texture? Half a knob turn? Full turn? Couple turns?
I have ran through the range quite extensively but not necessarily by very small increments. But I have kept the eye at the eyepiece the whole time monitoring for details.
I will PM you Peter, thanks heaps guys!
Cheers
Jon
