Monday 2nd evening 38/41F. After a cloudy afternoon the sky cleared for a high, half moon. A dark bank of cloud was rising from the SW so I dashed over to capture some lunar videos. I removed the D-ERF and PST etalon/filter stack. Then fitted the camera without removing the UV/IR filters from the ClickLock fitting in the tailpiece.
The monitor was filled with beautifully sharp detail with deep shadows on the terminator. This is just a quickly processed image to see what the stills looked like without sharpening, iMPPG or wavelets.I captured a lot of videos with slight overlaps to ensure I covered the lunar surface. More images later. Dinner beckons as the moon grows dim behind the cloud. It started at 250fps and dropped to only 54fps as the cloud thickened.
It is always a battle between short enough exposures and getting enough light. The 6" f/10 my be corrected for solar H-alpha but it looks nicely sharp on the moon. The ASI174 is capable of high frame rates on 640x480 and even 800x600. In clearer skies I expect it could manage full frame. While still maintaining its high speed on lunar videos.On the sun there is never a problem with enough light. I usually have gain set to 0 and still have very short exposures. All the lunar videos are on the laptop's internal SSD. So I need to transfer them to the external SSD hard drive. To be able to work on them indoors, in comfort on the PC.The danger is always of over-sharpening. Making the image look completely unnatural. The three images show different treatments while erring [hopefully] on the side of natural.
