SIGMA SD Quattro & Astro Image

Sigma SD Quattro is now available in Japan.

A right image was taken by BORG 36ED with SD Quattro. Unlike conventional bayer sensor camera, the details looks naturally resolved. As expected, I feel like Fuji’s outcome. I can’t wait for mine. I wish to test lunar and solar image with this camera ASAP.

 BORG 55FL F3.6 +SONY A7H + IDAS HEUIBII-52, 20 x 3 minutes unguided with Takahashi PM-1 mount

These targets must be the best fit for 200mm f.l. + full frame sensor. Takahashi PM-1 mount was well capable of tracking 200mm focal length in each 3 minutes. I guess 300mm looks still OK too. Let me see later.
