Deep Sky West: Takahashi TOA-150B and FLI ML16200 A collection by Scott Stirling

The TOA-150B astrograph is 150mm (5.91”) aperture x 1,100mm focal length at f/7. It weighs around 30 lbs (15kg) and costs around $15,000 USD new as of 2024.

The FLI ML16200 CCD camera pixel array is 4500 x 3600 at a pixel size of 6.0μm.

The arcseconds per pixel formula gives 206 * 6μm / 1,100mm = 1.12 arcseconds/pixel
