Narrowband

May 28, 2023: AR 3315 in H-alpha


Recommended Posts

Took a longer, 2000-frame SER file of the sun this morning, stacked 25% in AS!3, sharpened in ImPPG, and added pseudo colour in Gimp. Lots of detail both within the AR and its surroundings.

Images taken with the APM 80 mm F/6 triplet, with Beloptik tri-band ERF on Vixen Great Polaris mount, using an ASI174MM camera, Baader TZ-4 4x tele-centric, and Solar Spectrum 0.3 Å H-alpha filter.

Grey-scale:
