Sunspot AR4197

Sunspot AR4197 consists of about 50 spots and is 740MH big. Late afternoon clouds started to disappear and I installed my TAL200K. My parents were at home and I let them watch the big sunspot. Next I connected my ASI290MM camera and took some images. Seeing wasn't good which resulted in more then 500Gb of data. Stacking was done using AstroSurface but editing was done with IMPPG and CS4.

Setting: TAL200 f/8.5, barlow x2 and ASI290MM

Filters : ND5.0, IR/UV cut and OIII

Software: SharpCap, AstroSurface, IMPPG and CS4
