E-Corona woth Sol'Ex

Last year I tried a couple of times to capture the E-Corona of the Sun. This time, the Sun was higher in the sky and a UT noon time about 62°. Most of the time a blue sky with sometimes very dim high clouds. 

Setting:

TS/TLAPO 80/360 with ND filter and ASI290MM camerea

AZ/EQ6 mount

Solex Pro version with tilted continuum filter 

Camera temperature : 46°C

Seeing: moderate to poor

ROI Capture Area 1936x68

Tilt:-0,17°

Sx/Sy: 5,82

Binning 2x2

Exposure time: 1,79ms Gain 116

Frames per second : 550

Total scans : 105

Software: Sharpcap

Editing: Inti, JSOLEX, CS4, DeNoise AI

ImageMath by JSolex; setting by Cedric aswell as by Olivier. Below images are made using setting by Olivier.

Conclusion:

- use of tilted continuum filter makes it easy to find the area of interest (Fe XIV)

- impact of seeing conditions

- almost One hour of scanning, resulting in 105 images

- sky not all the time blue and transparent

- Sx/Sy to high; rate should be x32 in stead of x16

- some signal in the image but still to weak to really make the link with the E-corona
