For any one interested , here are a few photos of my home built , from parts got from here at IIS and others , Istar 127mm f8 achromat .
This lense is a stunner ! the views belie the fact that its only a 'Low'ly" achromat in some peoples eyes , but don't believe that for a minuite it performs very , very well .
Almost as good as my now sold NT triplet .
The American company Istar hand figure all their lenses to a high degree before sale and it shows in the final images , awesome stuff .
.
Hope you all enjoy and to any one contemplating building a refractor these Istar lenses are great value .
My OTA cost only $630 total , including focuser , finder , OTA , rings and Istar lense .
I did all the machine work my self so saved a bit there .
Total cost was only $1200 mounted , great for a world class 5 inch f8 refractor .
A big thanks to all who contributed to this build here at IIS and others .
Brian.
Cant seem to up load any more photos at the moment , will try again later .
