Thanks, Not sure how it will go for imaging but it looks promising.

Yes i have been following the CN thread on this 50ED but so far setting it up for imaging involves adapting it.

Thanks, but I am trying to steer clear of camera lenses, feeling that scopes provide better optical quality.

Thanks but as i said above.

I have the Tamron and it has a little CA at the edges of APSC when wide open but you'll be be well inside that with the ASI1600.

Thanks Steve, and all other camera lense respondents, i will investigate scope solutions, including upgrading my setup for mosaic automation through SGP, which i already have. This will preserve resolution.
