20070127 H-alpha and White Light

H-alpha obtained with Coronado SM40/BF10, Borg 45ED II with JMI NGF-S, DMK 31AF03, with and without Tele Vue 2x barlows.

White light obtained with Takahashi Sky90, Tele Vue 2x barlows (ND3 + Polarizer) and 5x Powermate (ND3 only), APM 1.25" Herschel Wedge.

A new active region AR930 is found on the solar limb.

Seeing 2/10, transparency 3/10, the poor seeing kills any small detail and the low transparency really hurts the contrast as well. Sorry for the poor image quality.
