The Sun, our star, this morning in the light of excited calcium ions. Highlighting the active regions and large scale plasma convection cells, the magnetic fields on the Sun are spectacular #science #astronomy #solarastronomy

The Sun is up on a beautiful Saturday morning and I am nearly ready to start observations 🌞🔭

My favorite solar image of the day

A spectacular image from today - it has it all (OK not really spectacular sunspots) AR 3152 in the upper RH (north eastern quadrant of the solar disk), great filaments in the southern hemisphere, gigantic prominence visible off the south western limb, flares off the south eastern limb - zoom in this image has amazing detail! More images from today to follow but this was just a beautiful example of why we observe the Sun.

Images taken from a cloud free Albert Park in inner Melbourne. Lunt130MT scope on an iOptron CEM70G mount and ZWO ASI174MM camera. H alpha images (656.5nm) Lunt double-stacked 130mm etalons. Images captured using Firecapture, and processed in AutoStakkert!3, RegiStax6 and Photoshop. #astronomy #solarphysics #solar #solarastronomy #sunspots

Rather pleased with my image of the Sun taken in Ca II K light (393.4nm). It gives a fascinating view of the active regions (AR3147 clearly visible near the Sun's eastern limb) and plasma convection cells #astronomy #solarphysics #sun

Taken with a #Lunt 130MT scope and #zwo ASI174MM camera, at 20221118 _001621 UT. Images processed using #AutoStakkert!3 #RegiStax6 and coloured in #photoshop

Getting a nearly 100 year old telescope at the Melbourne Observatory ready for viewing the Sun. The reflector has it's aperture stopped down and a Baader film cap attached #astronomy
