Hi all,
Since I am in the process fo upgrading my equipment with a Skywatcher 12" f4 newtonian and a JTW Astronomy P75 Trident Mount all to go into a new Observatory I am building under my Bortle 2 skies, I am going to be moving some scopes around.
I have an ED80 refractor (Brand unknown) I am going to be putting back into my small observatory so I can get a wider field of view than my current 8" f4 Newt. The reducer/flattner that came with the scope was a home made job by Bert (Aardvark), and it did a great job but it has a EOS camera adapter on it, which I cannot remove. Would the following field flattners/reducers from Bintel work on an ED80 telescope do you think? I would like to get as close to the 457mm focal length I have with the current reducer. Is there another option I am unaware of?
