  1. A closer look at the sunspot AR2833, reveals the dark feature of the Umbra and some details around the lighter Penumbra. The image was captured on 06/18/2021 at 1:15 PM ET, using a Daystar Quark H-Alpha filter with an internal 4x telecentric barlow, at 0.5 Angstrom bandwidth and a UV/IR filter to reduce scattered UV light & heating. The telescope used was a Lunt 80mm MT APO refractor and an Altair 174M Hypercam - monochrome, fan cooled camera, using 504 recorded SER images. The software used was AutoStakkert 3.1.4 & Registax 6 for stacking the image and wavelet enhancement.
