Inner corona and SOHO EIT 30.4nm

This image is the result of processing of two sets of eclipse images and SOHO EIT 30.4nm (He II) image. The innermost part of corona was reconstructed using digital images taken by Friedhelm Dorst, the more distant part was created according to images taken by Vojtech Rušin and the part obscured by the Moon was replaced by SOHO 30.4nm image. All images were aligned with subpixel precision. The position of the Moon corresponds the time of the 2nd contact therefore the solar and lunar limbs are nearly identical on one top-left side. The difference between the the solar and lunar limb is clearly visible on the opposite side.

Processing21 different images (16 R, 4 D, 1 SOHO) were used for image creation. Images were aligned by means of ACC 6.0 Match II module (D, SOHO) or by means of phase correlation technique (R), then processed using Corona 3.0 software. Final processing was done by ACC 6.0 software.
