June 25, 2023: Sun in WL and Ca-K

[michael.h.f.wilkinson]

Too bleedin' hot, but still captured the sun in two wavelengths, using my iOptron HEM15 mount for the first time. It worked smoothly. All taken with the APM 80 mm F/6 triplet, with Beloptik Tri-Band ERF, and ASI178MM camera, with Lunt Herschel wedge and Baader Solar Continuum filter for WL, and the Lunt B1800s Ca-K module

Good set Michael, love the Ca-K images.

A fine collection of images, always good to see Ca-K images.
