Re: [tmboptical] Barlows for ccd
- I reqorked a bit the images by sharpening and now they are much better than the once i posted.
Sorry have no such Zeiss Barlowlens left, but the Baader Planetraium sold 1.25 x and 1,70 are very good. The best is the new Baader Planetraium 3x CaF2 corrector barlow but starting only at 3 power. Also consider the highly corrected Takahashi Variextender starting at 1,6 power, a superb barlowlens too
