Details:
My first solar mosaic, captured last week on February 14. A lot of sunspots are visible: 3213, 3214, 3216, 3217, 3218, 3219, 3220, 3221, 3224, 3225, 3226, 3227, 3228.
There were some difficulties in making the mosaic because I had to join 20 panels with slightly different seeing conditions and with different field rotation due to the use of an alt-az mount. Some of the panels were spotless so I had to align them manually using solar granulation, but I also had to be quick during capture because solar granulation changes its pattern about every 5 minutes. I rotated each frame by a different angle to compensate field rotation.
Equipment:
- Celestron Nexstar 127slt maksutov telescope on its alt-az mount
- Astrosolar filter
- Zwo ADC
- Zwo Asi 120mc-s color camera
Processing:
- PIPP (debayer and conversion to monochrome using G and B channels, with a better quality than R)
- Avistack (stacking)
- Registax (sharpening)
- Adobe Photoshop (to join panels, add color and finishing touches)
