August 11, 2024: More disks, plus a close-up on an important anniversary

[michael.h.f.wilkinson]

Exactly a quarter of a century ago I stood on a parking place along the road near the town of Sarreguemines in the Alsace region, and through a four-minute break in the clouds could observe  and image my first total eclipse, using my C8 on its Great Polaris mount.

The same mount is still going strong, and with the more modest aperture of the APM 80mm F/6 triplet got me yet another batch of solar disks, and a detail shot with the 2.5x PowerMate inserted.

Ca-K, part inverted + pseudo colour:

Detail shot in white light, this time with dust bunnies removed using flats:

 

25 years ago I was using the C8 with Contax RTS-II camera and Fujichrome slide film. The image below is a scan of a print of the slide, so not that good, but the original slide got water damage when moving house.

Not the best of images, but I was chuffed to bits with it

Wow, that mount has done well still going after 25 years,  I too was in france for that total eclipse, just NNE of Paris in a village called Creil.   Magic.  

Great pictures by the way.
