Thor's Helmet at ISO 6400.
Hi,
Thor's Helmet with an hour and twelve minutes of data.
This really shows the value of using ISO 6400 with a cooler box under dark skies.
8” F/4 astrograph , baader type 3 coma corrector,. HEQ Pro 5 mount, orion mini guider.
Camera.
Unmodded Cannon 1100D plus cooler box. 36 subs at ISO 6400. Stacked in Deep Sky Stacker .Processed in Photoshop Cs2..
Cheers,
Justin.
