Description

Surprisingly good transparency and decent seeing despite a prolonged period of high pressure and no rain to clear the atmosphere.  
WL taken with the TEC250MC.  Ha with the 94mm f/7 refractor in DS mode and using a 3x barlow for the prominence animation.   Unfortunately by the time I started taken frames for the prominence animation, the camera had heated up considerably and was producing plenty of (horizontal) banding in the videos.   AS!3 did a good job ignoring those bad frames when stacking but the recording is a bit jumpy because of missing shots.

WL -  27ms / gain 210 / gamma 1 / 36fps - TEC250MC
Ha - 0.34ms / gain 210 / gamma 59 / 125fps - Full disc with 94mm f/7 at EFL 1,030mm
Ha - 5.3ms / gain 210 / gamma 70 / 107fps - Close up with 94mm f/7 at EFL 3,100mm
