The (Ha) Sun with filaments
Sunspots AR 4117 to AR 4120 & active prominence on western limb
26th June 2025
There are some nice active features on the solar surface today in (Ha) with quite a few long dark filaments, those smaller sunspots at this stage are not very active but that little prominence on the western limb is firing away :-)
(Ha) image taken with a Lunt 60mm solar telescope and attached Canon 700D camera, two sets of images were obtained with different exposures.
The exposure times I used were 1/320th second with ISO 200 for the disc and 1/15th second exposure time with ISO200 for the faint filaments. 25 images were captured and stacked in RegiStax6 and processed in PS.
The white light images were captured with the little Seestar S50 telescope and the attached solar filter, 20 images were captured and stacked in RegiStax6 and processed in PS.
