Hey everyone!
Got a SW Evolux 62ed that has been great for astro. Wife finally wanted a viewing session with an eyepiece. She's generally a fan of the planets and moon over DSO.
I bought a Baader Hyperion (1.25 & 2mm dual) 5mm as based on all the calculations it is well within the ability of the scope.
Scope is 400mm focal length and 62mm aperture. 80x seemed to be conservative based on everything I read and close to a conservative limit but still below ( I assumed 35x for every inch in order to not overdo it)
My issue is tonight when trying to view the moon, the piece was completely out of focus. No matter what I tried with moving the piece further away from the barrel, tilting it etc. I had no luck. I double checked with my DSLR and everything focused fine. Scope had time to acclimate to temperature and seeing was good.
Does the eyepiece need to be further back a la back focus? I had assumed just inserting it to the 2" level would make it good to go.
Thank you all for any insights!
