Equipment card


Same as last post, but adjusted to increase blue hue in DOP. The yellow cast is from the full moon sky glow, which I left unadjusted in the prior post. ZWO ASI294MC-pro at prime focus to 14.5” f4.3 Zambuto mirror Starmaster dob. 15-minutes total exposure in SharpCap livestack, 10C temperature setpoint. Sky commander goto and tracking. SharpCap stacked about 300 frames following field rotation and any tracking errors via 15 star alignment for each frame in live mode. Minor final adjustments with digital photo professional. The viewing site is a midwestern US city with Bortle 7-8 light polluted sky. Imaged July 4 2020 with full moon background.This combination of camera and software can be used in some very challenging conditions.
