31.08.2020 Fuzzy prom and W/L disk.

*

Monday 31st 70/64. Wasted some time trying to fathom out the drives. A lost cause. 

11.50 Lots of cloud. Captured some proms with the PST BF.

The area of surface disturbance wasn't cooperating with contrast nor the seeing conditions.

No images worth sharing. Even the prom was more like a chalk drawing after I had messed about with it.

The white light solar disk was an experiment with my 88mm, fluorite, APO, spotting scope and Lumix G9 camera. 25x on the Kowa '884 equates to 2000mm f/l equivalent with Micro 4/3. Image downsized from 5184 pixels original to 1000 for the blog.

I used a home made, full aperture Baader, solar foil filter. Quite pleased with the uniformity of brightness across the disk, limb darkening and decent limb sharpness. Shame there were no surface features to confirm best focus. Or even just for interest.
