Thursday 32F, overnight frost, cloud clearing to sunny periods by 12:00. 40F/44F Out/In dome.ASCOM AWR driver misbehaving again. CduC showing positive latitude again. Synced to parking place +1° altitude in the east.
6" objective steamed up inside! Have three dew bands on warming. Soft focus with dark blob from dewing on monitor. Cloud streaming across sun's image.
Clear minute or two. 94F at focus without filters but with D-ERF. 59F with KG3 + CCD. Using outdoor thermometer sensor.
It clouded over after lunch so I only started again at about 15:00. Capturing 1000 frame solar videos. 800x600 or 640x480. The image below is my first with the new telescope. Processed in AS!3, Registax6 and PhotoFiltre7.There seems to be some inconsistency across the image. Perhaps the "sweet spot" for which the PST etalon is well known. I have not settled on a particular etalon tuning point yet. Nor am I sure whether the internal dewing of the objective had completely cleared. I have to remove the D-ERF to see the objective behind it. With three dew bands wrapped around the immediate area it is quite a nuisance.It is probably easier to check for dewing from the tail end. That just requires removing the PST etalon & filter stack.
15:20 Retried the temperature readings despite the sun having sunk. considerably: The outside temp sensor was held against black foam for a minute or more with a sharp solar disk focused. The bright red spot on the black foam persists in my vision for a long time afterwards! 6" f/10 + D-ERF only: 120F!
D-ERF plus KG3 + CCD only 55F.
Dome air temp 43F. Outside 39F in shade.
Checked Kendrick dew band: 88F!
Astrozap: 60F at 12 o'clock on HitechAstro controller knob.
15:25 Clouded over again. Getting cold and breezy as dome turns further towards the SW wind.
Friday: 36-40F. A promising start with almost clear skies and bright sunshine has turned almost overcast by 10:15. Though there are some blue patches coming from the west. Then more cloud, then rain and now sunshine again.
