Hi guys,

 

 

Just wondering what everyone's thoughts are about this scope?

I currently use a 12.5" f/5 scope and need something it that will be more portable for me and will be only used for Deep Sky astrophotography.

 

The only issue I have with the spec I see is that there is only 51mm of back focus. My current set up uses 105mm of back focus which means I may be looking at having to get a new low profile filter wheel and OAG. As well, I currently use the Baader MPCC coma corrector and feel that I will also need a new Televue coma corrector to cope with the f/4 optics.

 

Also looks like the focuser will be inadequate and will need to be upgraded.

 

Thoughts?

 

John K.

Looks sexy!

The 51mm may be enough if the trusses are measured for it to be what its advertised to be
