H-Alpha Images on a quiet Sun (Singapore)

Post by yltansg » Sun Apr 29, 2018 7:45 am

28Apr18 was another poor day for solar imaging.

I started with the Celestron 150 refractor with a full aperture D-ERF + Lunt LS50 THa + ASI174 MM camera.

After this image, the seeing was so bad that I can't continue imaging with the 150mm Celestron OMNI XLT refractor. I switched over to my faithful work horse - Borg 76mm refractor + SolarScope SF50mm DS + Basler ace acA1920-155um

Image

Got the following:

Hi Derek, Rainer, Franco, Eric and Mark,

Thanks for your kind comments. There were no chances for imaging since then. The following are some HA close-up taken on the same day:
