Hi all
While testing my setup for possibly viewing Comet Mcnaut round perihelion in the daytime, I was testing the Argo Navis by locating planets.
Heres a shot of Mars, taken at around 2pm a few days ago! I was also using an infra red filter (passes 800nm and longer) This is a crop of the image, prime focus with 10 inch f5.6 newtonian, stack of 2 ISO 100 shots, shutter sp. around 125th sec.
To set up I aligned the Argo navis off the Sun (with full aperature solar filter on), moved scope away from Sun, removed filter, put on camera and dialled up Mars.
I used the remove gradient feature of Iris to flatten field, as there was some uneven glare present.
