A zoomed-in view of this area:
This was a first for me. First time I successfully managed a Hydrogen alpha image with a zoom lens (TeleVue PowerMate x 2.5). Previous attempts were usually curtailed by cloud or suffered from a lot of dust motes and an artefact called Newton’s Rings.
In this case, I had both dust and artefacts but used a flat frame to subtract them from my image which worked very well.
I also used Thierry Legault’s tip to tap the scope when taking the flat frame as this causes vibration which blurs out any residual image from the Sun.
Finally, I tried to find some prominences on the Sun’s limbs but nothing very remarkable:
Celestron 1000/102mm scope with 70mm Ha filter.
Skyris 273m CCD camera
Ioptron ZEQ25GT mount with Hinode guider.
