I haven't posted on here in a LONG time, the last 5 years has been a busy one with me buying a 7.5 acre site and building a house on it along with a bunch of observatories. The skies here offer an excellent southern horizon, with SQM readings in the non snow covered months of 21.5-21.8
I generally do visual while my CCD's are running and on Friday I picked up a set of pearl white Oberwerk BT100's along with the 22mm and 7mm EP pairs. Dealing with Kevin was first rate, the initial sale, prompt shipping and receiving the binos in perfect condition.
While waiting for them to arrive, I read a few threads on here regarding all aspects of the product. This post by Pinac https://www.cloudyni...werk/?p=8905369 lists a bunch of EP's that were compatible with the Oberwerk focuser.
The included 14mm work great, no issues with my IP or nose getting in the way. I measured the center to center on the adjusted EPS and it looks like my IP is 65mm.
The 22mm barrels are quite large and I can only get a full FOV by tilting my head down as my nose touches.
Using the 7mm is not possible for the same reason, but no doubt worse due to the small exit pupil.
I tested some of my other single EP's I have for my other scopes to see what came to focus, not necessarily what would clear my nose, since I only have singles.
10mm Meade MWA
18mm Coronado Cemax
32mm Antares Plossl
I'm particularly interested in some wide AFOV EP's like 24 Pans or the ES 24's, I'm curious if either of these come to focus, and how you found the comfort level with nose conflicts compared to the Oberwerk EP's?
So if you have an Oberwerk BT100XL, please post up what works for you and this thread can be an EP database for that optic.
edit: haha wow I need to update my equipment list!
