SOLAR IMAGES 2025 H-ALPHA IMAGES I started doing solar Hydrogen Alpha (Ha) observing and imaging after I got to acquire a low cost Coronado PST-Ha scope. After experimenting with compact digital camera as well as Philips Toucam 740K webcam, I have decided to use monochrome webcam in which the low cost Atik 1HS II monochrome webcam was used by me afterwards. All Ha images were taken by James Kevin Ty using ATK-1 HS II webcam on Coronado Personal Solar Telescope (PST) and 2x barlow lens. Lately in November 2013, ZWO ASI120MM webcam officially replaced my trusty ATIK-1HS2 webcam. Last December 27, 2016, I upgraded my Ha Imaging system from Coronado PST-Ha to Daystar Quark Chromosphere Ha Eyepiece Filter and officially retired my trusty PST. I also added the Borg 76ED refractor into my Ha imaging configurations aside from my TV-101 refractor and Canon EF 100-400mm f/4.5-5.6 IS L lens for flexibility. Starting 2023, I will be using ZWO ASI290MM webcam to image the Sun in place of my old trusty ZWO ASI120MM.
