Thanks Roland. As I saw the AP team heading to dinner tonight, I told George I would be picking his brain tomorrow for a shopping list for this. I See you have given me a parts list already so this

Re: solar filters
Just for the record, Al Nagler has stated that there is no problem using their NP scopes for solar viewing with a wedge. The rear elements are far enough forward in the light path that there is no

Re: solar filters
Pawel,
I justthought of how your big scopes can heat up telescope elements -- fieldflattener. I believe the image comes to focus in the flattener -- so thatwould definitely heat the lenses up.

Re: solar filters
Yes,it unscrews. Baader makes a special thin adapter ring that replacesit. Then you screw standard T2 accessories into thatring.

Definitively the wedge. I have beenusing it on my AP152 and the views were terrific and I had no issue gettinginfo focus with Canon. Views are better than baader Astrosolar. But ifyou just want

Re: solar filters
Again,by replacing the Baader 2" Click-Lock with their T2 threaded adapters, you cangain almost 3/4" (~19mm) of back focus.
I'vegot my Baader on an 80mm triplet refractor and can reach focus prime,

Re: solar filters
Trying to come to focus with the Baader wedge and my ZWO/NW127is now. Think I'm about 2-3 mm away for prime focus. Can get there (barely) with my 2.5 and 5x PowerMates.

Re: solar filters
I use to have a glass filter (not on a AP telescope but I don't think this is relevant to the current comparison).
Then I moved to a Lunt solar wedge.
Here are 2 example taken with the same telescope

Re: Meade lx 200(off topic help)
IIRC, PEC was programmed at the factory in the Classic LX200 andcouldn't be easily changed.
You should join the LX200-Classic Yahoo group and ask your questionsthere.

Mike,
What'sthis about a wedge not allowing photography? Who/what gave you thatidea?
Ofcourse you can image with a wedge. In fact, Baader makes two versions oftheir Herschel Wedge, the "V"
