Testing a 12" astrograph

This is a central crop of a test object that I like to use when testing scopes at the AP observatory. Image taken with a 12" astrograph at F8 using a 16803 FLI camera. 10 minute exposure on a slightly hazy night. I processed it in MaximDL to bring out the faint stars without blowing out the detail in the core.

Here is the full frame, reduced size to fit the AM limits.

Rolando,

Incredibly tight stars. Any indication of the FWHM?

Anthony.

Mighty fine!
