Active region 12599 imaged with my 150mm achromat, Baader Continuum filter and 5x Powermate. Granulation and penumbra filamentary structure are clearly visibile. The refractor I used is a short one being only a f/5 objective. Nevertheless provided with a strong green filter it is able to deliver very detailed images of the photosphere.
