Hi everyone,
I recently purchased a Meade 16mm SWA EP from the trading section and after using it, I am no longer able to use the EP's that came with my telescope
So I effectively only have one eye piece at the moment and have found 3 that I am interested in for a second one.
I have a 10" dob which has a length of 1200mm at F4.7 and I also have a 2x Barlow. So with the 16mm I currently have magnifications of 75x and 150x. I'm looking for something in between these, so 11mm-12mm. I don't wear glasses and have never had a problem with eye relief. The three contenders are:
12mm Edmund RKE
12mm (or is it a 12.5mm) University optics ortho HD
11mm Televue plossl
The university optics website lists the HD ortho as 12.5mm but in the picture it clearly says 12mm. If it is 12.5mm then its too close to my other EP for me and it's down to the other two.
I'm interested mainly in planetary viewing with these EP's and they seem somewhat similar to me but I had some specific questions. Out of the three, are there any which would not be recommended in a F4.7 scope and which would not barlow well?
The 12mm's plus my 16mm with barlow gives
75x, 100x,150x,200x
The 11mm plus my 16mm with barlow gives
75x, 109x,150x,218x
Any advice would be appreciated
