Sun H-Alpha with active prominences September 29, 2025
On the North Eastern limb a free prominence and on the Mid Western limb a long prominence moving away to space... so very active prominences.
The image was processed using new JSolex 4.1.1
This CaIIH is a very sharp image taken with Solex by James R. and 2nd Gen Slit.
Getting this sharp image is done with both:
- sharp edges
- camera sharpness
- collimator adjustment with focus on the dustlines; this seems working.

Comet C/2025 A6 (Lemmon)
This morning I took some images of Comet C/2025 A6 (Lemmon). The comet is currently 1,1AU away from Earth and will be at closest on October 21, 2025 on a distance of 0,59AU. Perihelion transit will take place on November 8th. Max brightness is predicted between these two days with the Comet low above the horizon after sunset.
