Tuesday 10th 32F, overnight frost. Early clear sky so it's back to the observatory to capture some solar H-alpha.10:50: Objectives still steamed up on all surfaces. Sun still behind neighbour's tree. Used gentle warmth from the hair drier on the 6". The Lacerta prism is well dewed up too.
Grr! The tree doesn't respond to the hair drier! Variable cloud moving across from the NW but still hope.
Gong Ha shows proms at 2, 4 and 8 o'clock. The 8 o'clock looks big enough to be well worth capturing. I'm missing the correct nomenclature for solar disk positioning. 8 o-clock is presumably SE provided the camera and image are correctly oriented to match the naked eye view.
Got no proms, Dad! Has the etalon gone off band? It is quite possible after all the adjustments to O-rings and moving the inner etalon arc. I might as well remove the rubber band and outer shell and turn the etalon directly with a screwdriver.
11:20 34F Found the 2 o'clock proms. Then the 4 o'clock. Poor contrast against H-a background sky. The objective is still steamed up inside! Now I really have to think about fitting heating bands! Still trying to find the 8 o'clock proms as a thick plate of cloud moves over the sun from the west. Blue behind, so I'm persevering. A breeze is picking up now. The forecast was for later cloud. Presumably the swing to the south west is bringing the cloud. I've suddenly lost the wireless internet again after earlier success. And now back again after opening Settings > Networks. Curious. Still less than 4 Mbps.
11:40 37F Solid cloud low down now. Only partially blue overhead.
12:30 Back indoors and the sun comes out! Grr?
