    Mars N.L. Lunar by DSLR 35mm lens
    From: Greg Rudzinski
    Date: 2020 Nov 26, 18:32 -0800

    See attached Mars Lunar captured by a Canon 2000D DSLR with a 35mm wide angle vintage Pentax Super Takumar. ISO 1600, 1/40 sec, f 5.6, 24MP and using a double polarizer to filter the Moon. A lucky -0.2' error has been reduced using Frank Reed's latest edition of lunar calculator.  Measured pixels were 2171 x .36 moa/px + 15.0' lens correction = distance 13° 16.6'.  The 35mm lens has a max practical field of view of 36°
