The Sun's Chromosphere in H-alpha, 20 September 2024 (In Explore)
Active Region 3825 is present in the upper left corner.
H-alpha image of the Sun's southern region using a ZWO ASI 174MM Astronomy Camera and a Daystar Quark Combo Chromosphere H-alpha filter with a Questar 3.5 50.5-inch focal length Maksutov-Cassegrain telescope with a Baader Energy Rejection Filter and a TeleVue 2.5x PowerMate. Best 50 of 500 frames each of both the surface and the prominences were captured with SharpCap 4.0 and aligned, stacked using Autostakkert! 3 with wavelets applied in Registax 6. Combining of the surface and prominences and final adjustments were made in Adobe CS5 and Luminar Neo.
