    Any experiences with Takahashi 60/76mm refractor telescope for terrestrial use?

    Just try tonight. With erecting prism, at infinity focus it still has about 10mm left. It works with a 2.25x barlow too but the barlow introduces very strong CA to my eyes. Note that now it is an fc-76duc form factor.

    In the photo it is an FS-60CB. I add the CQ1.7x onto it.

    Any experiences with Takahashi 60/76mm refractor telescope for terrestrial use?

    I am not sure where should I ask this question. I just get the Takahashi fs60cb and a cq1.7x extender and also the fc76dc tube that I can convert this setup to be fs60 (355mm FL), fs60Q (600mm), fc76dcu(570mm) and fc76Q (950mm). Now I am using it with william optics durabrite diagonal and...
